 it's pretty low great liquid line is kind of warm suction lines come back frozen and just shut off i don't think it's happy this video is brought to you in part by true tech tools quality tools essential support good morning guys so today we got three projects to do here we've got an old walk-in freezer over there that the glass got cracked and now is frosting up got a suction line there that has broken insulation so it's turned into a block of ice and then there's water dripping off the back of the evaporator it is hovering around 15 degrees these are Chrysler coping units i have switched this over to temperature control from pressure controls they are old but i guarantee you you will not see a true or any of the brands trostlin mantouac whatever last as long as these have i mean these things are built like with real metal stainless steel and aluminum got a sensing bulb right there comes down because the bottom got clocked down there so we got to check that now we have a walk in here i think they shut this one off this one's doing something i'm not sure what this doesn't work got some real nice packs there for drain line i guess it works looks like you can see through there so that's good not sure what the story is and this is things laying backwards though it's got a heck of a lean back okay here's the walk-in cooler all right so it just came on i have a feeling it was probably defrost let's go in here and see what exactly uh our clock is at temperature control has changed in 19 switched it to peole oil sometime in 22 it's kind of a contraption side glass looks full unless it's empty liquid line is kind of warm suction lines come back frozen and just shut off i don't think it's happy now what i did on this one here and there's not a whole lot of options with this thing really in a box something like that is we got a contactor there that's high voltage but it's inside of this container here fan's going the correct direction i replaced that back in 18 so fan motors 18 controller there's 19 conversion in 22 um obviously it's not the defrost clock which i made that so it was actually serviceable the last yin yang's made it very difficult this one here is very easy to get into i really don't want to replace that stupid thing but i have a feeling it's what we're going to do and i even made it so that you know it was isolated with that um contactor there so take the brunt of the uh amperage i mean it's lasted and the clock here is 19 so yeah the um so 20 21 22 23 four years so yeah there's the clock we're not in defrost we're doing about 35 minute off cycle well from what i'm seeing then depend on what that thermostat is which it looks like it's at 40 it's what's it's been screwed with let's turn it down a little bit see what it does appears to me her issues the thermostat fans have been running non-stop right at the 40 degree area let's take it down to 35 see how that does we'll let it run for a bit we'll go grab a thermometer and see what we're at well it just shut off so we're going to clamp our thermometer there right beside the sensing bulb which is laying right above the evaporator fan see how it does now may just let this roll for a bit and go on to one of the other ones but i kind of like doing one at a time unless i know what's exactly going on let's go over here so i can hear it running the refrigerant but no evaporator fans generally the evaporator fans are on with the lights which are off so if we can find out where the lights are at that might be why the fans ain't running because i can hear it like i said running and i don't seem to do anything i mean you've got thermostat right there solenoid on the other side of it don't see anything going in there to give me the power for my fans there it is goes up on the ceiling of this thing jump back over to this because it just shut off we're at 42 we're set for 35 coming down a little bit yet got 45 up there 41 here we need to turn down to 30 see how that comes in at it could be just a little out of calibration which wouldn't surprise me these thermostats have been junk lately had multiples go bad like you have digital ones but we don't usually use those see how that does for us if it'll hold normally they go off of that thermometer even though it's super super old they use it quite often so looks like we've got us a wonderful little device going on there like i said it goes up to there it's going to check the voltage but conveniently didn't use the terminals that weren't there let's go ahead and check and see if we can use light pin if you get light pin that we know that we probably are missing a neutral we always dig in deeper nope no light pin somebody's got a breaker off somewhere it's summertime and they just turned all this back on so some body's probably flipping breakers and not telling people where things are at so that's probably all that's wrong with this one here just turned us down a little bit lower we're currently at 25 which is all arbitrary numbers it's all springs so the breaker for this thing was over by the lunch line i noticed when i started feeling the liquid the liquid's hot but the evaporator was not cold so it tells me that it may be an issue there so now we've labeled it because i'm telling you people just don't realize how affordable markers are fans and panel h number 13 just it's just ignorant people are so lazy so our panel is way over here that's all this stuff's pretty old works all these new schools are bought garbage they're already like needing replacement stuff already in 10 years all these geothermals all this junk they put in because it's more efficient had nothing to problems with them yeah i'm going to get on the uh roof all right so we got that they're made labeled off so bounce back over to this thing so now we're at 32 which is fine as long as it shuts off here and then we can cycle up and on and off up and on and off you can tap 32 but you know as it cycles up to 38 or whatever it won't ever freeze the product got a dead ban there that's how the pressure control systems worked as they basically went down as low as they could but then they cycled all the way up and cut in at 38 39 degrees which was the pressure temperature relationship there the saturated temperature like it's already dropped down below 40 don't know if we can calibrate this yep it's got a little calibration knob there just shut off at 29.9 actually 30 so let this set for a bit we'll see what it comes in at all right so just turned on about 34 that's going to freeze so let's turn this up just a little bit yeah i could replace it but it just go out again it's about 25 let's see how that does good old white slippery rough so this is the cooler that over there is the freezer wow somebody actually rode in there with a marker they have five pounds of 404a on it look at that it looks like it's got bubbles it's pretty low great let's pull the top off this thing start looking for a leak hyper core technology micro channel did somebody clean it with a crazy cleaner of some sort caused it to leak let's find out clock's typical hard to turn but it turns they don't have it equally spaced out because you know the power is going to get turned off like it's just done now all right clock's never going to be right because they're going to constantly turn them off and stuff look at that looks like a little bit of oil there no reason for any oil to be there let's go grab the detector and see what we got let's double check this one cap here a little yep every freaking time they're never tight and that's either oil in the bottom there this has a tendency to leak and for constratus let's see what you can do today let's go down here this cap that i didn't really tighten up look at that and junk valves i'm not really sure why they do it if the compressor goes bad are you really going to reuse the refrigerant i mean come on really i know you can isolate it but it's like what's the point it's one more valve you got to pay for it's one more valve that you got to worry about leaking that's under super let's go to ppm ppm says we're getting up there the three four hundreds five hundreds and that's without it running that's with it static static static whatever all right so there's that one that one's probably your majority let's check our capillary goodies here we'll pull that cover off and get into the bellows i like always going to the back side that way it's a little cleaner usually it usually seems to always leak somewhere along the edge corners of the coil here so it's getting that corner there it could at least leak anywhere but that's the most prominent usually if it's a bad leak you're gonna pick it up and even in the cover here a little bit of a breeze out here but we're down in those bellows not getting anything on super i think we're fine on that sometimes you get guys blow their hoses off in there i had a little bit of a hit when it came in the door the hand's not on there that's not good is it maybe better off to go to the ppm mode see what we're getting you gotta watch that little button that vents out the air on the back your block it'll go off it's not good fans are running we have something over here by the freezer i do got a little bit of insulation i can cut and put on that let's go over here see if we can pick up anything they had a pretty full sight glass on this thing not a lot going on okay detect three just as sensitive if not more sometimes hasn't gone off yet got the fan turned off so we can try to scan the solenoid i did turn it off while it was running that way it would leave refrigerant on both sides of the coil i think we're good on that let's go ahead and recharge it get it going back over to this thing since we're jumping around holding somewhere in a 37 mark there 34 here has been shutting off about 33 coming on about 37 i tweaked it up maybe a degree of that i think we've got this one tweaked out i put right on the cover set it at like 27 degrees i know the guy here pretty good and he's pretty pretty knowledgeable he used to be our sales guy at my last place i worked at so i mean it's one of them things where if it's you know just out of calibration but is equally staying within a certain set range of on and off just adjust it mark it move on instead of buying another thermostat little bugs are everywhere little these things getting contactors all time on air condition here this up on top of a rough how'd you get all the way up here gotta put the electrical right through the freaking area there yeah we were pretty low but it hasn't ran all summer first time i've worked on this one i usually do all the work here got talking to me and this guy added a little too much refrigerant which my other one over there was low anyhow so i just used my hose and ejected the rest of the extra into this unit over here which as we're checking it out side glass is full now but the condenser coil is completely dirty gonna wash it out real quick it's a micro channel so usually these clean up pretty simple you can tell it's gotten washed by the rain water but it's not been getting it through the center of the coil so we'll go ahead and get that thing all sprayed off that way it can actually breathe that'll also allow us to check that charge make sure and see if it flashes off these usually don't take a lot to get them clean it really ain't much reason to get it with a chemical cleaner on these anyway you can about shove it right on through pretty thin they've got coil cleaners out there that are supposedly rated for it i don't trust it i don't want to be the one that finds out that didn't work very good and then they want to blame you for their coil leaking not my thought of having a good time mainly it was just dust i think but it was still enough to block the air otherwise i'd be really working these coils in the center plus this allow us to see if the headmaster controls working properly if we're not fully charged yet it'll start flashing off so let's go over here and take a look here yep flashing a little bit so you can see we're starting to get some light through there so we can use a little more in there not able to easily tell how much i added to it but all i know is that it was flashing just a little bit not bad and we'll see if we're still flashing or not i mean this ain't gonna be the perfect winter charge but it's gonna be a lot better than what it would be here on a warm day like we've got today so i got a ball valve right there able to start and stop it right there that one over there was pretty low i put six pounds in it holds five so my guesstimation will end up being about maybe a pound or two into this one they own supposed pieces of equipment so there's nothing wrong with switching it around legally epa wise this one here is nice and clean now and funny enough it actually shut off for the first time so it was low on charge and probably had high head pressure so just ran ran ran side glass was full until i cleaned it and now it's staying clean so we're gonna make a search for a little leak on that one um just got to finish washing out that coil over there and then insulate the suction line i think we might be all right by then the cooler downstairs is doing fine all right got that one cleaned out wasn't near as bad as the other one still did all under five gallons of water and uh rinsed her all out so let's see where we're out on this thing we're gonna do a pump down see where our receiver's at since we uh didn't do it the way i wanted to do it which is take her full and add 10 15 percent to it yeah it took a little too much out but what i did is i bled the hose all the way to the end there got liquid all out of it pulled off the high side which is liquid so we charge it in liquid form and wait before somebody flips out haven't had to do it very often but it uh at that point i didn't want to have to just blow it back into a recovery tank and just uh you know have to ride it off so i was able to make do with it all right so i went down there and used my test vial from emphicon it it's working so let's see if we can pick anything up with it running at 242 pounds ahead even though the fan's blown on it usually it'll catch it there's anything there i tightened it up pretty good and that's brass cap should be fine all right so we're gonna go ahead and check that other one over there go ahead and put this one back together 25 degree suction 101 condensing temp looking uh decent there there is a crap load of oil in here i don't think that's just dirt look at that same thing it's definitely going off there real surprise and that's about where all the oil's at i just checked the heat tape downstairs and replaced some of the insulation as you can see this insulation it's pretty old it's saturated down there and when it gets saturated with water uh it's not going to insulate at all and it's just going to transfer the cold right out to the outside and it's going to cause you issues so i went ahead and chopped off that glued it together and rolled it around the u-bend trap down there i think when this thing's running high head pressure and stuff like that from dirty coil that's when it leaks out the worst and obviously it wasn't like dead bone dry or anything like that it's not a huge leak but definitely ain't good to have any leak not a lot of pressure on it right now always like check the solenoid here the screw together types tend to leak a little bit check these caps out here too this one here i'm going to have to get some more insulation for on up into between the ceiling like i said heat tape's working and stuff like that i think it's low on charge it's causing a lot of my issues running a lot non-stop but the biggest thing was the ice balls what he was complaining about and a little bit of the ice downstairs i'm going to blow out the trap and then we should be good you can see it right here on the cap they got a junk basic cap there and i bet you the either the seals out of it and then somebody cranked it down tight and it's got a rubber seal in there we're going to put a brass cap on that thing and you figure it's about 90 degrees 85 degrees somewhere in the bull park out here right now that's all the more pressure it would have had so when it's running obviously that discharge gas is going to be coming through there a lot hotter higher pressure and i don't think they've had problems too much with this it wasn't like i said completely empty that insulation gets saturated is the other issue walking cooler is dropping a temp it's just about there the box over here with the thermostat issue it's good to go no problems there it's been holding temperature right in the mid 30s 35 to 38 area i think that's going to wrap this one up now the way i checked that was with this top done thermal imaging camera here this is something i've been trying out here recently you can get it on amazon it's pretty moderately priced it's a little bigger than some of the other ones out there it's like one of the big thick phones about twice the thickness of a regular phone but it's uh it has a pretty good size display on it it's android based boots up fairly decent speed wise yeah the resolution is still higher than what my FLIR was that i had prior to and resolution far speed is pretty quick so you go into this app here which is other apps and things like that but the focus point here is the thermal imager thermal imaging come into here all right so we're able to come in here we're able to see like i said whether or not that heat tape is working so you can see it right there working plain as day just like it's just as fast as my other one i've got it's i think better than my FLIR um you can pick these up on amazon so you can see plain as day right there that heat tape is working looks like it's uh running 42 degrees there on that you can see it coming across through there and down the wall so the thing i like about this one here is the frame rate so most of them are not that fast i mean that frame rate is 25 frames per second my FLIR was not even close to that now coming up here you can see everything seems to be pretty nice far as infiltration you can see the liquid line going across i'm not seeing any crazy infiltration in the building i can see a spot right there but that's in a corner not a real surprise and that's reflectiveness so you're going to have that no matter what you'll be able to see my reflection right there see it that's normally going to watch out for shiny surfaces uh i'm going to have them call a window place for that it's this door should add heat tape of some sort but i don't think they had it back then i don't know this door is probably older than me like i said um it seems to be working pretty good and uh but that's a look there at the top dawn it's got a few different things on there it's pretty cool hit it up swipe up you've got your temperature monitoring always a glare no matter what you do personal information gallery so you can go into calorie so there's the heat tape and stuff you can zoom in on it it's real simple easy boom boom boom this does have a wi-fi and pretty much all the same features my other ones i've got and like i said it's a little cheaper so i'll put a link for this down in the description down below if you guys want to check it out it does regular pictures and stuff it is a little thick it's about the about the size of my uh ultra 21 about twice the thickness though it's uh it's kind of thick it's got usb-c on the side of it it's got two cameras here it can do multiple different colors it's got speaker video player so you could actually play videos just like you put on your phone it's got internet on it calculator music sound recorder uh regular camera so here's regular camera that's actually a pretty decent camera uh compared to some of them that i've seen they're using that to do the double image up there you're able to take regular pictures plus your thermal imaging camera pictures but check it out guys if you're interested in it like i said though i'm going to replace that piece going up right about where you can see that folded uh arm reflexes uh i got this like i said just ran it through there and it held together pretty good and we'll come back and get that later well i'm just going to wrap this one up guys hope you enjoyed the video it's kind of all scattered brain and all over the place but that's sometimes how it goes they actually wanted me to check two or three other coolers and freezers but we just don't have time to do it today if you enjoyed it and you didn't want to see more like it make sure you give a thumbs up consider subscribing until next time thanks for watching catch you guys in the next one later
