 This here usually is heat build up from the defrost. I got the direct injection. Yeah, it's hitting on something. Man, I'm going to just kill the power to this thing while it's pumped down. This video is brought to you in part by TrueTech Tools. Quality tools, essential support. All right, so let's take a look, see what we got here. I was told that this one has a bad fan blade, so we brought it with us. At least these are beacons. That's a lot better than that last one I just worked on. And it looks like it's a beautiful negative five degrees in there. What they had is one of the fan blades was broke and now we have one that's stuck because I don't think it's properly defrosted. See if we can get this thing into a defrost and kind of go from there. Normally I'd recommend they block off the opening. If you're going to take out a fan blade, you want to block that off. That way it pulls from all the coil, not just from this section. And obviously we got a problem there with that. So see if we can put this thing in a defrost. I don't have beacons memorized, but they're not bad. I kind of like them. We got the front off here. It shows we're right at a negative four. We can go into the monitor section to see what we've got going on. Hit monitor. There's super heat. Hit enter. We're at two degrees. It's a little on the lower side. So here's defrost temperature negative 16. That should be the sensor. So we'll go through some of this stuff here in a second. Let's go ahead and get this thing into a defrost. I want to run it into that. So set defrost in temperature, DFT. That is going to be under program review. I kind of want to know are we having a problem with its setup that maybe that's causing some more issues. Defrost, save time, then it's 30. That's pretty safe. DFT in temperature 60. Probably not a problem with that either. I think what we've got here is we're just barely even sloped it off and strained. We can go 65. Force defrost. Pump down. There we go. So much simpler than that other board I had yesterday. This here usually is heat build up from the defrost. I mean it's defrost terminations at 60, 65 and 30 minutes. That's pretty common. There we go. This will give us a chance to see whether or not our defrost heater is working. Also let us know if our drain heater is working and stuff. So we're going to go ahead and yank that out. I don't think that's even hitting on anything. Let's find out. Yeah, it's hitting on something. That's why it wasn't spinning. Luckily these motors are pretty good about being resilient to those sort of things. There's no ice in here other than that one little spot. I see why they didn't block it off because we have chambers right there and there to keep it isolated and we have no ice build up in here at all. So we're looking pretty pretty good. Just got to change that blade honestly to make sure some of these wires aren't rubbing into anything. Probably going to be fine. I don't see any ice in any of these other ones either. Must have been something left over from maybe a bad defrost before or something like that that maybe was fixed and somebody just didn't clean up the mess afterwards. Kind of hard to say honestly. All right, so we've got our door jam here, doorjam.com. I bought one and they gave me a couple extra. You got to be careful though when they're that tight. It can cut it. I mean it's not indestructible but it's usually pretty tough but you got to watch it. But doorjam.com guys these things are pretty awesome. Plus it tells them you know not to close take it away and remove it. That's the big thing. Let's go ahead and get this other one in there real quick because obviously defrost's not going to last for so long. We're at 45 already so it's going to be kicking out of defrost here real quick. Somebody lost the nut on that one. That's not good. Got a little bit of crackage there. And what I'm seeing it looks like the defrost is set correctly. We don't really have anything going on here. It feels like that defrost heater right there is working. I'm not going to put my hand dead on it but I think you know what here's that ice on the side again. It may have been running a little too long so maybe we need to lower the defrost. That way it shuts off a little sooner because like right now that coil is completely empty and what happens is you build up too much heat in there and that's going to cause the build up and so we may change that defrost termination a little lower. They got a cooler in front of it so that's going to condition the space before they get in here. It might be able to get away with less defrost. Once it goes in defrost the more money is saved because you're not using enough energy to do it because you know you've got to use electricity to bring the temperature up. You got to use energy to get the temperature back down. I think I'm going to go ahead and pop all these out and make sure they're all clean because actually otherwise I have a bad feeling we're going to get a repeat call on it and that's the last thing we want. The only thing you could do is go out there and hit that with hot water then you get to wipe it off really good. I'm judging from where the marks are where they had them before. They didn't have it very far into the shroud so I think that's starting to get a little rounded. See 60-63 it's almost up to 65 that I moved it to pretty quick. These things kick on here. See we got a little bit of ice right there on that one and a little bit there so we've really got to make this thing stop. Look here it's doing that. You can see there's way too much heat in there so we need to terminate faster. I'm going to lower that down a little bit that way it doesn't get so warm. I'm going to say that's probably a good majority of what's going on here. Watching it obviously is a huge deal and if we wouldn't have seen that we wouldn't have known what was really wrong with it and I would have changed it and I would have created more problems than I was fixing. Yeah and then that thing's going to wait. I need to see what the drip time is on it afterwards too. Man I'm going to just kill the power to this thing while it's pumped down. Okay we're going to be really careful in this nice white roof. Here is that freezer unit. Once again they love this design obviously. I was looking all over for the breaker downstairs and I wasn't going to find it in time before it just kicked back out so let's get down there and see if we can get that before we fall and kill ourselves on this beautiful roof. We got the power off. Let's see where that defrost temperature sensor's at but you can see where we have got way too much moisture buildup back here. This is ridiculously way too much heat. I think it's the reason why they set that other one in the coil. This one don't have one in the coil. I mean my goodness you can see all that freaking. That's way too hot. There it is. See it right there that green one? It's on the wall. That'd be a lot more useful if it wasn't there. Now here is that other sensor I was talking about. Let's see where it's at right there. So it's taken it quite a while to sense that heat. I mean they're trying to pick it up off of that aluminum wall but I'm just going to lower the temp a little bit. It was 60. I don't think it needs to be probably no more than 45 maybe. 55 is in the arm. We're going to change that once we get the power back on. Let's finish going ahead and yanking these fan blades and getting them de-iced completely because that is what's going on. Unless that temperature probe is off that one's pretty free and clear. That one got a little bit right there. We can knock that off. Oh yeah we're going to need to yank the fan blade out on that one. I like these Inglend 20812. I've got a lot of this stuff down in my description area where you go to the Amazon link. If it's not something you can get at two tech tools I have links for it and Amazon. Yep that's just from yeah because the pan is completely clean. No ice at all in there. Some of that wiped up. I always love people that make 16 trips. If there's one thing I can tell you new guys, get what you need on the first trip. Don't come back before 60 times. So much time wasted. You can see the employees down there making 50 trips and grabbing one box instead of two or three boxes. All right let's take a look at this setup again. Let's change that programming. Let's go into program review. A&E is your type which is electric defrost refrigerant type which is 404. BOT is box temperature negative five sounds about right. Superheat eight SLA which is whether it's master or slave. DDF demand on defrost enabled no. DFN number defrost four. DFF which is defrost sale safe time 30. DFT temperature which I tinkered it wasn't 60. Let's take it down to maybe 53 and hit enter. That's probably not going to make a huge difference but we could we could actually try let's try 50 and enter. There we go alarm high temperature five low temperature negative 15 ALT alarm 10 60 minutes for alarms FC whether Fahrenheit or Celsius. Now we can go into the monitor make sure our sensors are accurate so we'll hit clear hit monitor superheat expansion valve set point zero which means it's closed FCT suction temperature 29 so it's muster released our nuts were to bat now anyhow and defrost temperature 18 that's that sensor on the side DFE defrost elapsed time 20 minutes so 20 minutes is how long it took for the last time defrost temperature that's the temperature sensor self outdoor temperature tells it whether you know it's probably gonna have some low ambient issues AC voltage we are at 26 looking good there this one here doesn't monitor the temperature of the coil which I honestly I believe it would help if they did let's try this first if that don't work we can always come back like I said this is a newer set of stores that we haven't done a lot for so before I go in they're changing a bunch of things and they since they have their own main list guys I don't want to go change in a bunch of stuff see how that goes I don't think I like the pink for everything it don't work real great but it's something clear we're back out of it let's go up on the roof one more time and make sure that our side glass is full oh great that's nice didn't even feel that I can't that's kind of frozen into place you just don't even feel stuff and it's practically numb sure frost bites just make believe right there obviously is our freezer we got the direct injection to keep it cool big monster receiver okay there's your top there's some of your relays for the fans and stuff outdoor thermostat which probably shuts down one of the fans I bet there's your outdoor sensor which I'm always surprised they've got sort of time delay which they've already got cranked down almost to non-existent everything looks pretty normal I mean we can check all these different things but man I don't want to tear in a bunch of stuff I mean you got a little bit of marking there but I mainly wanted to see my side glass which even with these here the side glasses are right there you can barely see them okay they are solid sometimes you got to give it the old licking stick there we go full side glass green at that the other one is also green and full at that so we are we are at least full on the the go-go juice now I feel a little more confident that we can leave without having an obvious callback as always guys make sure you check out these other channels that I post up here in a second make sure you check out Ryan and Steve they both got great channels as far as what we did today we've got basically just an easy fan blade change but we decided to check a little bit deeper into it and make sure why was we having that ice on there to begin with which we found out that determination is a little higher than what you typically need that's going to change based on the environment that it's in the communities that it's in and with this one here they have a cooler in front of it you know it's not got as much humidity but it's still going to have some leave it to potential employees leaving doors open even in the cooler because it's so cold that they may leave it open and cause it to still get a lot of humidity in there but determination we lowered at 10 degrees from a 60 to 50 I was actually going to go the other direction it's actually going to make it worse if next thing I'm going to put on the paperwork that we should probably move it into the evaporator if this doesn't work and then we can go from there I'm going to fill in their facility manager to what's going on that way he knows what's going on communications is key to prevent potential callbacks as long as everyone knows what's going on and they're aware of it in advance before the problem happens that's the best way to deal with it in my opinion if you guys haven't subscribed please consider doing so until next time we'll catch you on the next one later
