 Alright guys we're getting ready to look at an ice machine that's not working correctly. One side was harvesting quicker than the other almost to the point where basically the machine would lock out and serve several times when the machine did lock out. Anyhow the audio was recorded on the wrong side of the microphone so it's going to sound a little bit different but I think you guys will enjoy the video. We do replace the harvest valve for the right side and the filter dryer and we do the proper evacuation techniques and things like that which some of those things people may not agree with but it is what it is. Let's go ahead and get started and as always thanks for watching, consider subscribing, make sure you hit the like button. It really helps grow the channel which influences me to continue making videos for you. This video is brought to you in part by TrueTech Tools, Quality Tools Essential Support. Good morning guys, I'm here to work on an ice machine and this ice machine has been having issues not harvesting on the right side, the right side is slower, the left side is faster. See what we've got going on here? It doesn't work to every time. What's that? Yeah, so what we've got is it's not one to draw and the problem we found the last time I was here is we get about 60 degrees warmer on the right side than we do on the left side. We checked our temperatures here on our hot gas valves here. This is where it brings in the cool venti-brew as they call it. This side here works as it should. This side over here does not and we're going to be tight in this space here so it's going to be very tight. This dryer, it needs to be changed which I didn't get the dam fall so we're going to have to mix four or more. They claim it's special. The hot gas valve here is the one we're going to replace which is fairly easy to get to. All the pumps work on it. The pressure charge was a little low a while back. Little leak surge couldn't find anything. It took the line set up through the wall so you can't tell if they've made any connections in the wall so it's very possible that they did. So we're going to get this thing recovered. We've got to do a three-point evacuation on this because they do have solenoids and check valves in here so we've got to make sure we get those get around those so that we can get all the refrigerant out. So we're going to go ahead and get started with our recovery and we'll get our refrigerant tank prepped, get it back on it and get it pulled out. We're going to do here's we're going to go ahead and use this T. I've got the valve core pulled out of the one. I'm going to pull it out of the other one and we'll just jump it with the hose down to it. Don't need it. So we'll go ahead and yank it out and speed it up quite a bit. And you'll see I've got that one yanked out too. It's liquid. So we're going to go through the suction side because it doesn't have a dip tube so we can actually expel it a little quicker. Okay up there on top you can see the ice machine is right here on the right hand side. So let's go ahead and start pulling liquid first. As you can see on the back side here there somebody just got way too happy with the 90s and in the fascinates I have a bad feeling they may have ended up to change. Okay I have one here this was for another ice machine and it's three eighths. This might it's not often we have Emerson dryers it's not very big. I mean there's no desiccant value to it at all. That really really really scares me that it's not big enough and then I restrict my flow and cause this callback. Right here is actually the Manitouac one. The problem is it's quarter inch. So let's go with the three eighths 083. Here are a couple dryers in there a little bit of everything. I'm not going to run all over town to get a different brand dryer. So a pound or two, good deal. Now we can release and let the pressure bleed off. So what we're doing this we're just going to bleed some nitrogen through this right now that way we can now breeze it and then we'll pretty much re-braise it back in after bleeding nitrogen through it. Okay here's our valve came with multiple different copper fittings. You can see right there there is a screen in front of that at least that's what it looks like to me and I think that there's just to help catch debris that's coming through so it doesn't get stuck in the in the valve mechanism. I have a funny feeling somebody didn't use nitrogen and it's probably gummed up full of charcoal crap. Compare it looks to me like it's the right one, look over some getting it apart and not be the right one. That works pretty good there. We don't want to burn nothing up. So my good friends at refrigeration technologies made me my biker blanket here which looks really good even with direct you know hits from the brazing torch no problems. You don't have to wet it but I like to wet it just as extra because I want this thing to last. I mean you can't out the full in the water. It's a lot cheaper than the other one that's very similar to it. It's not as big but generally I'm not swinging my torch all over the place roasting everything. I just check them while they're running wide open and I've got as much as we need. Now so you guys know even though this is stainless on the outside it's copper on the inside. This is not going to take much heat at all to get this thing to warm up. You do not want to burn that copper coating off and you can use regular brazing alloy for this thing. Keep that in mind and we're going to try to right try to have to keep this thing wet. Definitely wouldn't be a bad idea or get on and get off as fast as possible. As easy as you do it. So if you ever hold it away from it so that it's cooling down then let's go ahead and see if you can pull this thing straight up. It should come right off. There we go. Right on to the copper. So after the copper, it's going to come right up. It's something black. I always like to confirm it makes it feel much better as I'm making a pair that I don't get it all back together and all of a sudden oh my goodness it still works. Here the clip goes through this direction. It does not go through very quickly at all. It's very restrictive. Let's do it on this one. There's that one versus you can hear the difference. There's a restriction here. Why is it restricted? I don't know. Maybe they got it too hot. Maybe some crap got in there. I don't know. That's definitely an issue. Some nitrogen. Get all of it out of there. It would be great if we can get this thing completely together and then raise it. I don't know if we're able to do that very easily. And it's not like this stainless steel is going to flex. Okay I'm going to heat up one at a time. I don't think I can get it on there quick enough and off of there quick enough to do it. Also once again my good friends at Wet Rag gave me some good stuff here. I like this better than the other stuff even though they claim the others a little bit better. What I like about this is it doesn't leave residue all over the place. That's not a pain in the butt to get it off. But we're going to pack this around the body of it. If you get too much in here it's going to be really hard to get this thing hot. And the last thing we can do is sit there and have to fight heat on this thing forever trying to get it warm enough that we can braise on it. And I'm saying because if you've got too much blocker on there it can make it very difficult to get it hot enough to braise it between your putty and the metal. You want complete surface contact. You want conduction through the putty right to your item. What we're going to do is heat that up. I'll shut it straight down and then we'll add a touch of braise to it. We'll cool it back down and then we'll put it together for the other one. This is really hard working condition here and you get crap everywhere. I can't get my stuff in other locations because everybody's walking right through here. They always put the ice machine right in the middle of the way because it's they need everyone needs to get to it. I'm holding onto that with my hand. There we go. Put it right in. And it takes as much alloy that's on there. Pretty sure we've got it in here. Let's go ahead and cool it down. This works really nice. Have a little bit of water right here. Yes you don't want to cool down the joint right away but we don't want to let it accumulate either. So I'm more worried about potentially getting damage from deep than I am about this outer joint not being perfectly strong as possible. You got to kind of balance it. I will sometimes bend these towards each other so the tension is towards them like that and then when I put them together and they line up they should feed together fairly decent. There's some tension on the one side. I'm going to try to heat up this copper pipe here so that it goes towards it. Oh yeah. Honestly I'm going to heat it up a little bit and see if it sucked in. Oh we can do it. I'm going to hold it there for a second. Way more heat than I wanted but we got it. I'm not putting it directly on the joint. I'm actually putting it towards the back side of it where it's still just solid pipe. That way I'm not putting cooling effect directly to it and kind of letting it conduct over to it. Some would disagree with that but if I melt that mylar inside there even though I've got all this other heat sink compound on there I don't I'm not thinking of changes. Looks to me that we are all up inside that so we're going to go ahead and take off our putty. We'll re-wet that and we'll throw it back in the back in the pail there. See how usually I clean up the other stuff seems like it just leaves a real nasty residue on there just I don't know. I like helping those who help me you know. They believe in my channel and what I'm trying to do and they have a product that's good. Hey I'm all about helping them out. They don't even know who you are. I'll see if their competitor knows who I am. And it's cheaper than the other stuff. Got 43 pounds on there. I can hear it going through. I think we're good. All right let's go ahead and take that back off and let's get that filter dryer yank out of there. We're going to try to get a good straight section here. I just straightened it out. So we're gonna go ahead and cut that and then I'm going to show you a couple new expanding tools that I got from a hill mower here that not many people probably need unless you're doing the big stuff but really is going to come in handy if I don't have a copper fitting and I need it. Onto my hill mower here. I've been wanting to get this for a while and my good friends over at TrueTechTools got it for me. So here's an inch and an eighth and here's an inch and three eighths. So I've got now and they make some of you know we have to two inch but here's a seven eighths. You can see the difference between seven eighths and inch and an eighth and compared to inch and three eighths. Usually that's the most I'll see for most any repairs anything bigger than that we're going to get into you know having what we need to do the repair off fittings and miscellaneous things it's not going to be a spot repair. I just thought hey it's going to come in handy if I wanted to show you guys that that they do have that for your hill mower and as always guys you can go on TrueTechTools save yourself eight percent on pretty much about everything there's maybe some items that aren't covered but use promo survival. I pretty much get a finder's fee for you guys buying it that it lets them know that you guys are actually watching the channel and so they continue to provide me stuff like this so I can show whether it works or not and because I really don't make money off of it it's just mainly in trade for the tools and so you can always trust my opinion on it if it's something I don't like I usually I'm not going to talk about it so when I like something I like to talk about it a lot on anything up to anything bigger than three eighths but I do it just in case I'll do a slight swedge I'll put my hand on it so I can feel it getting bigger and there we go we got ourselves a nice coupling and I've got it all the way down to quarter inch I don't think there's anybody else any of them that's got one of those down to a quarter inch which you do have to heat up the metal a little bit if you don't want to split it but it pretty much goes like that for any of them any of them that are using that same type of expanding device I purchased this one with my own money I don't know year two year and a half ago tech back emcee I love the looks of it man it's just it's kind of big and bulky I'm hoping that mb5b is going to be a little more along the sizes of what I need I need something just a little bit bigger the big thing is something that can actually set up straight enough fall all over the place like the bag does all right so you can see this goober gober here they don't belong up here that looks like it's three eighths and somebody squeezed a half inch thing down and that could have been causing issues too I don't know not going full with it yeah fortunately it looks like there's a lot of work been done on this line so I got a little sandpaper here we'll sand it up move it down and put some nitrogen through it again and get this thing breezed in we get a better look at it there I don't know why they didn't put it downstairs where it belonged at all right let's go get some nitrogen on it and you gotta watch this rubber roof too last thing you want is to drop some molten grease stuff on there which looks like so very easily to happen we're going to get that inside pipe form first because that's the one that's going to travel the heat into the unit into the socket socket pocket you know like I call it both things and I'm mainly talking like this for the new guys you know that they don't you can't teach somebody how to braze real great in school you know when I came out of school I sucked they didn't really other than read a book off to you you've got to learn and develop it but you know it's sometimes you just see people put the heat on the outside here and just basic common sense things if you think about it but honestly I just like to throw out some of the things that I've learned over the way over the years to hopefully make it a little easier for other people nice and indulged looks like a solder joint this one here has a metal piece on one side and the mesh on the other so the mesh on this one is on the ongoing side so in theory yeah if it back washes it's still going to get caught coming back through it's solid core on top of that it's not that hot I mean it's it's hot but you know we can cool it down I'd rather cool it down after the fact than I would beforehand when it comes to some of these I've just had so many problems getting the dryer warm enough to absorb the heat that I said you stay on it forever that looks a little bit better in the old one did for sure we're gonna get that down here in the bottom that thing a little bit warm and then it should fall right up into our nice and fast heat's gonna rise okay a little warmer than I wanted but the heat can get away from you pretty darn quick I'm not perfect once again viper big blue and this one right here all the backside we're looking pretty good so let's go ahead and get this thing evacuating get this thing up and run and see how it goes low side valve pull the straighter the receiver valve I hooked my little pressure gauge on the high side just to show that it's pulling through in there too which is probably helping it leap around we're at 677 okay we just zeroed everything out we bled everything over there we're pulling off the liquid side of the tank we're going to recover it right into the machine here's the instructions I didn't see 15% several solders recommended although so we're bearing solder in the 5% 55% range can be used seconds and direct heat to the solenoid socket they call it sockets all right it looks like we got 190 ounces in there so we lost 10 ounces 16 ounces lost a pound uh that's good then from bleeding and things like that and we didn't turn it on I still got to add a pound of refrigerant already been up on the roof and uh turned on the disconnect to it all right let's go ahead and zero that out and let's put it here it's six extra ounces as we can see we are in dancing temperature running 235 which her head pressure control is theoretically set to 225 she'll be going in for a quick quick we've got one valve we have one per there on the out one side or the right side panel and we have a mode out one that'll allow us to measure what our temperatures are if we're more in lines artificial on the actual output plate you can see that we are pretty much neck and neck 95 25 25 generally it's not that close but we're looking pretty good so far feeling the ice here very close this thing has been making ice every 10 minutes 11 minutes something like that we are starting to get some clicks which usually means we are done to use the means we are starting to break the ice it's expanding too far and usually this would go into harvest about any second now we're 13 minutes 52 seconds we were at 18 minutes on outgoing evaporated temperatures there it goes so unfortunately I don't have exact seconds on here but we're going to watch this thing and like I said it had been dropping on the one side versus there we go 65.4 versus 63.2 and about four degrees there I'm waiting to see which one drops first the problem is running into with the right side just would not drop at all uh-oh look at this the right one with the problem in it looks like it might be they're going to do the same time sweet baby jesus there we go that is beautiful we have over two minutes three minutes five minutes longer on that side and it just would not drop so right there's perfect we're watching for more times and that's okay so you were right and we are good to go getting ready to release we are 45 seconds into harvest left sides loosening up right sides loosening up temperature seven degrees right side even dropped faster can't really count on how much warmer or not warmer it is it seems but definitely temperature is getting cooler on the right side so it could shut it off that's good I'm telling her to have reverse problems now that would be a bunch of crap but I wanted to replace all this crap at one time there we go all right I apologize the video obviously had the audio on the wrong side of the microphone the front versus the back so it's not going to sound that great if you made it this long I really appreciate you guys watching it it was already diagnosed so sorry we didn't get around to getting that recorded at that time we needed to get the job done and didn't really want to screw around recording because there was a lot of diagnostics involved and a lot of different miscellaneous tests just to make certain what exactly was causing the problem so it is what it is I appreciate you guys watching it I really do and if you guys would please hit a like and consider subscribing if you haven't till next time guys we'll catch you on the next one later
