 This video is brought to you in part by TrueTech Tools. Quality tools, essential support. See that right there? That's good old grease. My favorite. Let's go work on an oven. At least it's got some pizza in it. Nope, not that one. This Ramajama. 35-12 is the set point. Actual 10-4-70. What it does, it hits 5-12-ish and then shuts down. All these R's, freaking furnaces, that cook pizza. The building's being pulled into a negative, but I don't think that's what's causing it. It's good, we until she gets up to temp here. We just hit set point. Just shut off. This is where we'll usually act up, as you can see. But paint comes right back on immediately. There we go. I lost that heat really fast probably because they're sucking everything out of the building like they are. A lot of 3-degree variants. Dropping. Not gonna act stupid right away. Now, I did have this panel off because I was in here checking my wires. Looks like I said, this is nothing special. Got a draft motor, gas valve, ignition module, other solenoid, got a pilot, and then you've got the burner. This has been replaced once. I built this shield the last time because it was getting too much heat in there. This right here, there's a electric heater element like you'd see on an old electric furnace. The coil is 24 volts. Didn't see anything loose in there. Amperage was 0.6. Really not seeing nothing right at this given moment. I had changed the pilot assembly on this once before. We could have a flame sensor issue, it's hard to say. Okay, let's see what we get here. We're gonna go to ground, I'm not a big fan of that. Thermostat, it's getting 25 volts. Watch it go out here in a second. Actually, it's staying at 25. Okay. Thermostat's not cutting out. They must be cutting the solenoid and killing the main valve. You see it? Where's the non-solenoid on there? So what I think we're doing is we're energizing this right here, which is the solenoid. You know, it's not like I work on these every day, but there's certain circumstances that cause us to have to work on them. Solenoid. Technically, it's running right now. That's kind of weird. So we'll watch this here. Like that right there, we'll see. The old trickaroo. That's how I check solenoids on everything and it will watch us right here. Just went out and the amperage went away. So it's cycling that valve right there. Yep, there it went again. So yeah, of course now it's working perfectly fine and cycling it every time. I'll move this 65 inch screw. The temperature control is right here. This is what's cycling our temperature on and off or cycling our solenoid on and off. Yeah, schematic being kind of nice. If we can read it. It's just tiny. Nothing's cutting now. That's what sucks. Nothing's cutting. Cycling just fine. So even though I can't see it, the pilot's probably staying lit the whole time, so we're not flame-sensitive. This is completely solid here. So I could drill a hole in there so they can see the blank. That way we know when it doesn't work correctly, we'll know if we're having a failure on that or if we're having a problem with it getting to here. Because they're claiming that we're getting power. It's saying on the display. Now who knows if they're really noticing that or not. They could just be saying yep, yep, yep, agree with you, agree with you. With heat being on. See how the heat there on? It may not really be on. They may not notice the difference. But yep, there it is. It's that one right there. That's your one that's kicking it on and off. All right, we're just going to go ahead and print one up here. That way we know what we got. 120 volt solenoid that makes it simple. Might just label this thing over here so we know where it goes. All right, so we're going to make one assist from temp control. Previate it as best as we can. This thing ain't acting up. Let's try to clean the pile and assembly. I don't know what else to do to it. And that would be the only thing but shut it down. And as much as this thing runs, it would not surprise me if that's what's going on. All right, we're down to a chilly 320 degrees. It's been nice if it would have acted up. See if we can't get this thing out of here. Loosen this turt up. Good, they didn't put one in there. We have to turn the gas off though. Which they conveniently put that back here where you can't really get into it very well either. And instead of putting multiples, they just put one. Probably fall off later, at least I tried. So there you go. We'll go ahead and get in there and clean that up. I mean it's the most logical thing that's caused a problem but you can't be sure when it don't act up. The easiest thing to do is get a little brush in there. Clean it up with a brandy brush. Don't have any grease on it or anything at all. As you can see, there's not a lot to this thing. You just got that solenoid to cycle in. And here you've got, just shoots it in there. And that blows it on in. And it has two distributor type plates that the heat comes out. Not a lot to it. But when it don't act up, what do you do? So we're going to go with the most common thing, pilot being dirty. The flame sensor anyhow. And put her back together and move on. And if we have to come back, we have to come back. At least we did something. There's nothing I can do about it if it's not going to act up while I'm here. Now this thing here is not going to stay shut. It's kind of critical that it does. And they go out and grab me a screw and put it right in there. That way it holds in place. Alright, let's turn this thing back on. You should be able to see that fan motor kick on. It should run. It says heat is on. Okay, so that little heater must warm up. See that heater warms up, it should come on. Come on, hot dog. Maybe that's what's going on with it. I think I got everything back the way it was. Thermostat and that. See how the heat shows it's being on. It's more dirty. Lower. Alright, let's get her probes down and start checking for voltages. See where we're missing the voltage at. Bottom of it. Yeah. The heat from the bottom. But it only heats from the top. It all heats from the top. But that heat get it brownier than that. That ain't even brown at all. I don't know, I didn't build it. I'm just saying that the heat comes from the top from what I see. I might be wrong. I don't know about Evans. We have everything turned on so it sounds to me we might have finally got it to packed up. So, let's get this sucker back together. That was an S with a sucker like a lollipop. And see if we, our problem is right here. Because that might be our issue. See, it says heat is on. Now that we went through and actually figured out what one's what. Let's go ahead and see if that power there. Like that. Into here. I have no power coming out of this. Check these things. That's closed or at least appears to be closed. Closed. Do you have 120 volts on it? 120 volts on that. 120 volts on that. Checking between it and no voltage. So, checking across it. They do show to be closed. Or you can check it from around on both sides. And if it's on both sides and it's 120 volts circuit, not a 230 volts circuit. You know, it's getting through. It's 230 volts circuit. You always have 120 volts on there because they're only breaking one leg. There's all I unhooked. Those are these two wires here. Those I didn't unhook at all. And that's it. Now I can't see this very good. The nearsightedness is already screwed up. And you with readers, I can't see that. It's all screwed up. But that contact is pulled in. I'm not seeing that fan motor spin near as fast as what I think it should be spinning. I think the centripetal switch on that is not making because the motors act about. And that could be our issue. That that motor's not doing its thing. Won't allow power to get on through to the next couple things. 208. They're cooking now, it looks like. Yeah, at the bottom I had to check gas off to work on this one. Alright, so I'm going through here checking my stuff. And I had a wire fall out. See that? So I'm going to turn the power off and get that crammed back up underneath there. I swear I had voltage. Well, I would have had voltage because it's coming from the top. I think we single-phased our motor. I'm pretty sure it's three-phased. I'm going to go kill power and get that butt up and there's the outruns. That was tight, so I don't know how it fell out. I probably just didn't stick it in far enough. I hate when it happens. Everybody trims these little puppies so short. Now I'm going to see if I can kind of tuck them all these. Kick them back on, see what happens. Hopefully it ruins. Oh, look at that. That motor didn't sound very good. That definitely would be why that motor had to get up to full speed. Once that was up to speed, and boom. Now as you noticed, we didn't do anything really much in there, but one of those wires must have been loose, and I bet you anything, that's what happened. That thing came out of there. Now that motor doesn't sound real healthy. I don't know if it's three-phased. If it's three-phased, then the motor screwed. Let's see what kind of juice we're pulling on the amperage here. I bet you it's single-phase with a freaking capacitor, and even though it's a three-phase contact, you're probably just feeding other things. Either way, that would have caused some issues in that motor. I mean, if it's working, I know how this is. If it's working, I'll leave it go. I do see no capacitors. So there's no capacitor on that thing unless it's on the other side. Everything's back together. I'll put those off, and I think we're going to wrap it up. Time will tell if that was the only thing. But cleaning the pilot surely didn't hurt it none. Got that screw in there to help keep that door shut. I mean, there's a little bit of gap there, but I don't feel any air pushing out, so it's mainly shoving that burner gas out the front. The big motor back here is actually driving it down. Everything's back on. I originally had a spacer behind it to keep it from getting too hot, and I have a feeling somebody may have removed that because it definitely has a lot of heat back here. It's just not a good spot for electronics. You would have figured they would have put it down low. We're going to use... Nope. However, those are the K2s. Here we go. Got to admit, these things are pretty wicked. They can cut more than water ties. They can cut some really good stuff. So we got a little hole here, and you can actually see the little LED light that's not lit, which is good, directly head-on. It's not the prettiest thing in the world, but this oven's not the prettiest thing in the world either, and I told them the owner before I did it, so it's not like I just drilled a hole right through his stuff without letting him know. And if it helps him diagnose what's going on, that's all he cares about. All right, so that was one of those tricky ones. I believe we got it. If not, we'll have to go back. They know what to do. That's the whole thing. We did communications with the manager, so if it does act up, they know where to start looking at. If you guys enjoyed the video and you want to see more like it, you know what to do. Until next time, we'll catch you on the next one. Later.
