 you guys asked about the bone beacon systems got one here it's reading 34 degrees it's a pump down it's already pumped down got our list of things that the abbreviations mean and EDN is pumped out but I noticed when I got here because I'm here to do the PM is outside the suction line it's crossed it over into a big old monster block vise but yet on the inside here my coil doesn't look all that bad actually looks fairly decent same thing they've got it teed together this one here is another one this is a master sleeve we're gonna check it and see if there's something we were going on I noticed it kicked on a pump down a little bit more so may have something leaking by just gonna check in my contactor and it's fine and loose nothing's sticking on that and I just replaced that last year sure looks like floodback or something like that all right without it running which it just kicked on it was at the positive I think 10 pounds or something like that I heard a click watch it for a minute here I don't know if that's falling or not you're a little bit of squealing in the compressor but before I do that I'm go ahead just check my wires here we have common a compressor right there so let's see whether it's calling for it well obviously the control is calling for it to run on compressor common got 24 volts what's interesting on the Copeland units they said they are using a solenoid valve in front of the electronic expansion valves they were having some issues this one doesn't do that shut off it's like about five pounds pressure to me so at least it's not pumping into a vacuum this has a headmaster I didn't check the side glass I forgot to look a peek inside here does have a headmaster bearings are obviously not getting lubricated and that's outside of the motor so you're good to usually notate that the the bearings are starting to go dry you can see daylight through the coil it's already coming back on gauge on to the high side there to see what our high side is see whether or not the headmaster working for refrigerants 404 super heat box temperature these are electric defrost beer cooler so they're running colder it looks like we're going to refrigerate so hopefully we'll find an easy leak in here let's go back over to this thing and we'll double check the same thing here this does have its own temperature sensor right there and this one here has its own one there's your electronic expansion valve your suction pressure transducer then you're gonna have a temperature sensor on the and that would probably be a little better if it was actually attached now wonder if that came out of there that's where it belongs that if it wasn't in there I sure said didn't pull very hard on it yeah look at that it won't fit in so basically right there's our issue the sensor for the suction line is not attached so how's it gonna set the super heat this one over here right there you can see that white going in that's where it should be at so it's not going to set the super heat very well if it's not sensing the suction temperature so I'm gonna get that warmed up so I can get that probe inside there I don't know if water drifted into it and pushed it out or what we're gonna fix that and see how things work all right there's the sensor now I've warmed it up a little bit my torch was able to get it inside there you can see that it's gotten water in it in the past and it's cracked that little holder there so water's probably dripped into it and just shoved water stripped into there and there's just shoved that sensor on out that probably should have had some sort of a thumb gum or something like that in there to help adjust it first let's go back into our super heat oxygen 732 but you know what let's go for 33 just a little extra you never know the sensors are gonna be a little out of whack okay so there's that super heat set for eight all right I hit the monitor button right there and you can select what you want to see so cooling super neat currently right now the super heat was like zero so that's not real impressive I remember correct I had a few issues with this cooler before let's go over here and program review well at least that one's doing halfway decent we may have an issue with that sensor and they never got in place I see defrost temperature sensors that white one there it goes up and that fall ice that probably ain't good blue one here comes back to suction temp we'll look through and see what the suction temperature is actually reading all right suction temperature says it's 17 which I think is what my gauge is reading outside let's go over this other one and see what its suction temperature is SCT all right we put it into a forced defrost which is kind of convenient how they've got that right there on the board and then I took my monitor switch and I went to defrost temperature so I can see what the temperature is that it's sensing we got the ice melted off up here all right what I ended up doing here is I've raised my super heat up 10 defrost temperature termination is going to be 55 because it hits it really fast then it's in drain so there ain't a whole lot on this one here to set because it's the slave unit but when you come over to the master and I went ahead and do the same thing to it I'm going to grab my clamp we'll see what we've got okay what we're using here is a adjustable probe here where I can take surface temperature 40 degrees is what it's reading dead nuts on top of it and I have 40 degrees close enough for government work we're at 40 so the sensor is working it is reading correctly and this would be a good time to go over to our temperature sensor up top there which is a defrost termination temperature it's reading 45 degrees and we're 55 it's 43 I had over 50 something so we definitely need to get the correct sensor it's not going to cause our issues that's going to be uh because they had it set at 40 originally and it was obviously hitting that so it was terminating temperature or terminating on temperature as it should but the everything else seems to be fine room temperature let's check that yet but other than that I think our biggest issue was is our set points are a little bit out of whack look at that it pulled out on its own see that I did not do that all right it's a little stronger than I thought I was able to put a little bit of a pinch on that right there but I'm going to put a wire tie on it too to less chance of it doing that so I gotta go and grab one of those and then it's time to get busy on the rest of the p.m but basically that's the beacon beacon two it's pretty simple really I just haven't had a chance to work with it a whole lot otherwise it's really kind of cool you set your super heat what you want no more jacking around with springs and all that crap and you tell it when you want to defrost and all that and then it just does it so you know that's really cool thing about it it's just simplistic as that and if you go to to bone sight you're going to be able to download the manual like that one out in the truck that they gave me and every now and again I have to reference it so that one kicked on this one here and DFT it's dropping so yeah all right well I'm going to lower this one back down to 43 also if it matches that one neither one of them like I said originally had any filled up with ice so they've been defrosting fine but once again it's one of the things where you're just kind of talking out loud and you're trying to figure out what's going on and and then you just go from there basically we just weren't sensing temperature correctly was a lot of it that wraps this one up here I don't think anything important is going to happen the rest of it but as you have learned from the last few videos I think it's going to be easy in and out and it ends up not being it this right here is another Cooper Atkins probe I really like it it's part number 50418-K American made they're not cheap but it does a heck of a good job I'm really happy with them one last thing I don't want to forget right there is five what that is my suction pressure obviously since this thing is calculating super heat you've got to make sure your suction pressure SCP that it's accurate because if that's not accurate it's not going to be able to calculate super heat both of them are showing 5 psi it just pumped down so temperatures and pressures are correct I got that wire tied into place there on the side so that sensor should not move and that does finish this one up all right looking out here we have a 21 22 degree super heat that's at the compressor before the accumulator we had none before if not a negative but super heat is what I'm focusing on here we've got our 25 I think it's what they usually call for for the minimum for the compressor so it's it's doing much better than what it was we know that it's not going in down into a negative and this thing looks like it might been here for a couple years the compressors were placed in 2010 so it's uh seems to be operating fairly good and look at the side glass we got full side glass the reason why it was dumping all the refrigerant through the coil now that it's metering it correctly it's holding it back and it's keeping a full side glass amazing how that works I'm going to scan it over for leaks for giggles just to be safe and then just order those defrost termination temperature sensors
