 So we've got us a sub-cooler like a submarine sandwich cooler That is not keeping very good temperature for what I'm told so let's go in here and see what we got going on This is the little sub thing really it's more condiments than it is anything But you can see we've got the cold rails what really it is and it's currently working the complaint is It doesn't work very often and then she comes up and she kicks Hit about in that area. She said they've got a pressure switch back here So when she's hitting it the pressure switch is making You know having to do is climb back in there and then so what I'm saying is is that she's hitting it It's coming on so what we're gonna do we're gonna turn it off That's gonna let the pressures come off then we're gonna go ahead and gauge up on it the Pressures most likely that's low is probably into it negatives So instead of sucking in some extra air and non-condensibles We'll go ahead and get that thing up And then we'll see if it's low. We'll turn it on see if it's low and if it is Probably just pull the refrigerant out weigh it back in it's a leaker. They haven't fixed it yet They're not going to fix it obviously. So what's the point of wasting a whole lot of time on it? At this point we're just gonna get it going and then we can go work on an oven Which we got an oven over there. We can go work on. This is the static pressure right here And we're dropping down fairly Quickly grant the products close to temp. I believe She said it was working when we got here. So it's only thing kind of stinks. So here's the temperature deal here Which that's kind of hidden on the other side Not anywhere easy to get to Really a horrible design Now it could be that junk switch down there too. You can see it's just one of them lightweight little Piece of junk look like switch you'd use on a fog lamp or whatever Can't quite make out what the rating is on it, but usually they're barely Enough amperage to handle it I'd rather see a full-size man switch on there Instead of those little pansy looking pieces of junk They're just shut off for four psi That's uh kind of down there in the lower end See if it comes right back up and immediately kicks on. That's the case. We know we've got some issues All right, it just immediately came back on if it's going to short cycle like that That's going to take that compressor out and run it into overload So we've definitely got an issue here with an in-no on charge Like I said, this is known for leaking, but they don't want to fix it So we're just going to go ahead and get it to pull the charge out weigh it in It only holds 12 ounces you could probably add three or four ounces would be okay But I don't want to overcharge it and I really don't want to have to calculate it figure out exactly what What my operating pressures are I just want to weigh it into the factory spec charge and call it a day It's not of course my time to sit there and spend all day trying to figure out something like that We're pulling it down right now Ended up changing the Trader core tool The straighter port right there That other thing freaking lint and Even pulled a vacuum on it. It was taken forever. So got that chopped out Just used my hand torch since it's quarter inch Just barely it's hot enough I was able to burn it in there without the starter but Regular I get this thing pulled down Recharge it. Obviously, I'm not going for a perfect vacuum. I'm not changing filter dryers any of that stuff They've been told this needs to be replaced. It's just a waste of time waste of money They know it leaks and it just really is no point in doing any of the above As long as the filter dryers, you know filtering basics that's about all we can do You know if we're going for gold fine, but for something like this where we know it has a leak It's a consistent continual problem. That's just what the way it is It just doesn't make no sense to waste any time or money more than on something that you know has got issues like this Eventually it's going to finally fry itself and then they're going to have to get a new system But until then you can see that the Metal is rotting out. They have to put a pan down there to catch the water that drips. It's just No sense of putting a lot of time or effort into it. Honestly, I hate sounding like that, but that's just the way it is Because they're a good customer On a lot of the other things that we work on We're going to work on the stove. I don't easily have to work on stoves, but it's not that big of a deal So let's go look at that here in just a minute. See if we get this done Let me recharge it back to the 12 ounces maybe went one extra one over Kind of just watch and see where it ends up stopping at kind of where it hovers at See if acts a little bit better The rails up here looks like they have started to fall So we got a little bit of time there to where it's going to take a while To run so we'll be able to watch it and kind of get a better sense of what it's doing It's been running a good five minutes or so. So we're holding pretty good in here at 12 pounds So as before just dropping down to like four. I think it was This is going to allow to longer run time And uh It should be good on that one We're going to go and get working on that stove and then we'll come back and check it after we're done Here's something you should realize if you can see it. It's pretty kind of bright out here This is a power lines. That's how much flux lines are given off there. You can see it It's picking those lines up off that so I'm sure there's somewhere I know the big ones around here going 600,000. That's probably 300. I bet something like that you can tell based off of How long the insulators are But i'm not for certain what that one is however Living near one of these things is a good way to get cancer Okay, so this is a tri-star oven Not one of the more expensive ones But there's really no such thing as a cheap one now what you'll notice on some of these cheaper ones Is this kind of The doors Switch is not accurate when you close it it gets caught So they have to literally Yeah, this is a really cheap one compared to a Trying to think of the different brands But yeah, i'm not too impressed What you're gonna find is Either the flame sensor is an issue or whatever they're saying that they turn it on sometimes it doesn't get warm So let's get this thing apart take a look inside here and see what we got going on Only nice thing about these is the parts are so loose But they come off nice and easy Chances are that's high voltage. I wouldn't be surprised That's why I Look at that. You got a fake burner there. I actually got oh, that's kind of a weird setup Get two orifices there for corny How's that work? Oh, look at that. Okay, so they're using a u-shape burner all the way to the end That feeds all the down there and then comes back this direction Haven't quite seen one like that before There's your pilot assembly We'll go grab the thermometer Temperature probe put in there. See where we're holding in and see how far it's off now before we jump into that temperature deal Here's how you adjust your doors Little aluminum deals there generally they Are all out of whack like these are See how out of whack they are So we'll end up loosening up That nut there and there we'll get it adjusted so it closes correctly and we'll throw some oil on there See how we can get this maybe fixed up. We're gonna do it. I'll just do it. All right. All right. Tell me if this is a little bit better Don't have to time it don't have to push the other door with the other hand. You just shut it That's the way you do it All I ended up doing is loosening that one even though I loosened that one too But this is the one I tightened up that made the door pull in quicker It can be very confusing. I recommend doing just one at a time and A lot of times. I mean one turn is all that took And see how aluminum's likely stretching along with the chain So that should do a lot better than what it was One of the few nice things about this being hot Is all the fittings come apart easy This one's actually easier than some of the more expensive ones granted two five sixteenth screws of all that holds up And that eventually will strip out Make good and sure that all that gets back together Sealed up no leaks The reason why I removed that was to make it a little easier. You could have Bent this around but you can see it's been bent before and I really don't want to take a chance of it Possibly kinking and breaking this one here. It's a combination of flame and spark combined You can see that it's kind of dirty there It's not going to sense as well. So we'll go ahead and clean that up with the wire brush We'll double check the pilot too Oh look at that There's a lot of what's probably going on just barely got a thread holding that in there So that's gotten really hot quite a few times Sometimes these can be pulled out but I am real leery of finding out if this is one of them That flame sends a rod there. Sometimes they'll have it grinded down to a point You can slide the wire on but I don't think this is one of those You got that pulled apart. You can see the orifice is right there One of the little tricks sometimes you can use is a straight head screwdriver Go in there and you can usually break that loose It did allow it to pull out You can see right through it. No problem The old wiper roux everything's good to go there So Keep that back in there and get it back in This here you got to watch out for that exposed wire because it can arc to Anything that's closer to ground than what the end of that is and that can cause the spark to not reach the end of the Pilot which you could also cause it to not obviously establish a fan flame This is nothing but in all reality if you really think about it the convection of it here Is nothing more than a gas furnace an 80% gas furnace with exposed burners ribbon burners intermittent ignition pilot And everything else stays the same thermostat just like a freaking furnace does It's really nothing special You have a door interlock which is just like a door on the blower And uh high and low fan heat cool And then fan uh light on fancy fancy. That's about all there is so far. Let's see what else we got here See if this gets it or not I got the Flame rod cleaned up looks a lot nicer. It's just a stainless steel rod What I ended up doing was just twisting the wire So that kind of chokes up the Wire so they ain't as much exposed. It's not the way I'll prefer it But I must slide this thing up to see much of an insulator. It's not made for Spark insulating but more heat And obviously it must have moved because it didn't protect the wire much Sometimes this is one of the things you get some of the cheaper brands out there You can just tell it's It's a total clone of a blog it a blog. It's what I was trying to think of earlier They only got one glass instead of two glasses Um, they look nice at first or they're new But you start seeing real paint first hand real quick where things are different Just lighter weight hinges. You can just tell how thin a metal that is it's not near as heavy as some of the Logits are going ahead and blew through the orifices there made sure they were wide open. We're good there So we can get this back into place like I was saying that kind of Went underneath there That raises up Connects together Just like that. All right. So like I said, we've got everything back together the burners look like they're adjusted properly You've got your air shutter right there If it was on propane something like that and you did just that You know, they seem like they're open wide like they're supposed to be Thing there The burners appear to be burning pretty good. You can see that front burner there and you can see how it kind of loops Over and back again sort of That looks pretty clean and clear. I don't see nothing dropping out the pilot That looks pretty healthy there What we've got we've got a special thermistor here built for ovens The part number on it. I always I really really like Cooper Atkins products That's the part number of it Um I've got all these things usually listed in my tool links down below We're using the fluk 52 2 This is an 8 meter, but you don't have to have something this fancy But you definitely should have something like that if you're gonna be checking ovens out It's built to withstand the heat We're set at 350 which is usually a common point 350 425 whatever We're gonna see if where we are at on it. We're gonna see if it's accurate Sometimes on the back of these they've got an adjustment that you can adjust to calibrate it I did put the sensor On the inside at the very top real close to the probe the bulb And we're still cooking along We did grab some spray we're gonna spray that Make sure we don't have any leaks On that union and I want is a leak inside the oven Check that there too because I don't want you never know the last union that came through and got stupid with it Yeah, see we actually got a little bit of the leak right there So we'll go ahead and see if we can tighten that up a little bit more Probably would have never noticed it, but we'll go ahead and tighten that up a little more I'm gonna have to take it apart and clean the mating surfaces on there because that's not Getting any tighter. It's as tight as I can get it We are just about ready to shut off here Now what I'll do is I'll hit my min max and it's going to fluctuate usually once I've worked on before usually about five degrees Some more some more or less you gotta remember. I don't have any books on this stuff It's just using your common knowledge of what you know for my gas furnace and just go from there Yeah, that's reason why that freaking igniter there got burned up so bad that like right on that that thing Not a very good design there. It just turned off And we're at 358 Now look at starting to leave temperature already Now this is a cheap one. This is a regular bald mercury ball bold style Some of the nicer ones have actual thermistors Let's see See what our min max is here Watches for a couple cycles and we'll get that taken apart We're kind of cleaning that up. You can see the gunk in there So you get that all cleaned up in there Get the wire brush on it clean that up And then I may put a little something on just the threads never ever on the mating surface the mating surface That's the reason why they got brass there Brass is supposed to kind of squish up against the metal here, which I've already cleaned that metal up But we may put a little bit of proto there on just the threads To help lubricate the threads only never on the mating surface That's a good way to have a leak. I got it back together cleaned off any residue there Let's go ahead and see if we get this thing turned up a little bit. Let's go to 375 here See if it'll call Yeah, you all go to let's go on up to 400 there And it's not the most accurate controller in the world, but it was holding the 350th area Now that it's running We can check it It's been a good couple of minutes. We have no No bubbles at all there. So we're good to go there. Of course, we're holding pretty good on our temperature We got about 395 or set for around 400 It's kind of 386 so As good as I can expect for a Old-fashioned mechanical thermostat. I'm going to recommend we probably replace that pilot assembly I really don't like the way that is but who knows they may not want to mess with it We'll get the information here. We came back out here and everything looks good on it and everything looks fine So it seems like it's working pretty good Kind of go from there. We came back over here and we're looking at it. We are at 370 area Still hasn't came on yet Can't help but wonder maybe this is what they were having problems with maybe come up to temperature Didn't ever come back up. Let's turn this thermostat up Came on as soon as I moved it That's quite a difference, but look how fast I think can bring the temperature back up Hey, it kind of sound sounds like you might have a Thermostat a little out of whack. I'm going to recommend we do the thermostat and the pilot assembly That that seems like it should be a lot more accurate than that Yep flying held up pretty decent I kind of didn't realize that kind of happened but Look at that. No stick That's great I left it in there when I was working on it All guys, if you enjoyed the video and you want to see more like it Don't forget to hit the thumbs up button.
