 Welcome back viewers. Got a couple things here to disassemble and of course their sealed objects. Got a filter dryer which came out of a ice machine. If you talk to Manitowoc they'll tell you that their dryer is better than a standard dryer because they have a screen in there to protect any backwash if you want to call it that when it goes into a harvest. We're going to cut it apart and see if there's any truth to that and then I have a TXV here that went bad, had real high super heat and high subcooling. It would not work in the heat mode. It was a heat pump slash geothermal. I've replaced quite a few of these. We're going to see how it looks on the inside. You can see the screen doesn't look very good. I actually cut it out of the system. I didn't sweat it out. I don't think that happened on trip home. I turned it back to the truck. A good grief that looks like it's all the way around. And then we got a reversing valve. This is a little bitty one. I think enough you can stick your whole freaking thumb in there. It's an inch and an eighth I think or inch and three eighths one or the other. But we're going to split that puppy down the side and take a look inside of it. I've got to be honest I've never really split a TXV open like this before. Usually I like to take them apart and take a look inside when you can unbolt them. This one was not able to be done that way. You can see the plates right there on the left hand side where that's the diaphragm and that pushes in there against the piston there. That right there is a spring. There's the plunger coming down to there and you can see the nasty crap in there. I'm going to say that screen was pretty nasty. So the question is why was there so much crap in a clean system that has never been opened before? Well if you know or heard at one point Copeland had some issues with some oil that they put in the compressors. Now they claim that a lot of these aren't affected by it. But it was an oil that was made to keep the compressor from rusting while it was setting around to be used for manufacturing. Well it ended up having some ill effects once they got the POE oil in there. And it seems like I've got a lot of these TXVs that get gummed up. And don't know for certain if this was one of them that was affected by it. But I've seen this happen over and over again. Now obviously some of this garbage in here is going to be from cutting it with the grinder. Yeah you can see that crud is in that screen. Problem is it was not serviceable. Can't take it apart to clean it. So you're going to replace the whole thing when you're doing it. These are the springs. Push back up on the diaphragm. Right there. And that's your port. Its job is to equalize it out and the unit shuts off. Gotta admit this is the first one I've had like this. The little bulb there is definitely a little odd. Normally it's like a pin. There's the whole number on the valve. Just cut apart the Dan Foss. There's the felt. It goes up against the screen. You can see it comes in. Okay I'm just tearing the living snot out of this thing. You can see what the desk it looks like which I'm sure quite a few have seen. I'm going to keep on busting this thing out of there. And lucky they're felt on the other side. So they weren't kidding. They actually have felt on both sides. Yep. Got a fine mesh screen there. That is the outgoing side. Get the felt there. Then you had the desk in after behind it. And had the felt on the other side which was that piece right there. I do know that the Sporlin basic Sporlins do not have that felt on both sides. Okay. And now we have the reversing valve. That one's going to be a little more interesting. You can see the U-bend in there. That's a big ol' burger. This is on that. I know it was 30 ton unit so it was 15 ton a piece. Yeah I'm going to see if I can't split it down down the side here and then down the other side. Tell you what guys it makes a heck of a mess. Not real. I haven't done this too many times so it ain't very good cut. But got her apart. Check that out. I think that fancy orange hog snot. Hell yeah. So you've already seen these I'm sure cut apart on a picture diagram. But here is the tubes that shift back and forth. It blows the refrigerant one side or the other. It slides back and forth. Which this one was stuck. It's kind of like a metal. That's a rubber. It's got a rubber feel to it. And here's the little diverter just loops it in over. So that's what you got. Now this don't look too good. Check that out. I would say that this right here was supposed to have probably white plastic all the way around it. That don't look good. I would say that's probably some of the reason why it might have failed. I could be crazy but I don't look good. And this piece here stays stationary as you can probably imagine. You see right there is a little port. And the other port should be right there. There it is. There's that port. So basically depending on how this little burger here shifts, it's basically a miniature version of what the big part is. It shifts this way or that way. And it directs the flow from here to there. That's what your solenoid does when it's on there. That piece there should come out. Here's the other half of that piece. Okay I pulled that piece out and you can see right there it went down in that area there. That right there basically shifting back and forth just like the big part. Real scientific I know. You can see where she's been rubbing back and forth. I love shack of NEM. Yes. Well what did we find out? Well we found out our screen was plugged up for whatever reason for material of some sort. Did it in. It's not serviceable. Luckily the new one is able to be taken apart. Just here I'm going to say that plastic crap is somewhere in the system. How was I to know? I highly doubt that's formed by a machine that way because that looks like hell. And um yes there is a difference in the dryer the way it's built. I mean Mexico. So there is a difference in the dryers. They're not crazy just wanting to sell you their dryer. Go figure. And then there was a thermostat here. There was word that it might have been sticking. We can pop it apart. Ain't a whole heck of a lot to that. You can check contact points on it. What the heck. Let's tear it apart. Okay now we got this part coming apart. If you noticed it's basically got spring mechanisms in there. That kind of makes click on and off of your switch mechanism there. Now you can see right there looks like it's got a little burnt. And the contact points don't look really good. There it might make a little better. You can see where it's been arcing on that piece right there. Contact points are inside there. Let's pull them out of there. And there's contact points. Now I didn't condemn the switch so I was kind of curious whether it was really a problem or not because it was running when I got there. And there's a couple other things I found too but that definitely it's not good. You can see how that could stick on or possibly not make contact. But you got all the amperage of the compressor going through these little dinky contact points which is why a lot of them are now using isolation relays. So you're not putting all the amperage on the little dinky switch. And the only thing we haven't cut apart is that TXV bulb. So let's go ahead and take a peek at that and then we'll wrap this up. All right, that's kind of interesting. Got the bulb open. It looks to me like there's some sort of felt in there. Let's see if we can pull that out of there. Let me tore it apart. That is a piece of felt. It does smell a little funny. But it really ain't nothing in there but a big old chamber with that felt thing in there probably because it's liquid refrigerant I'm sure of some sort. They never have told us exactly what it is as far as I know. But that's what's inside there. A lot of times what I'll do is I'll cut the sensing bulb just to see if it was dead when I'm done. Just to kind of see, you know, was it the bulb that went bad? Was it the piston stock? Was it something else? Who knows. But there's our little miss. And yes, we did wear not only safety glasses but we wore a shield. I wear mine like that. Anyway, I got the hard hat and the safety glasses and I can take that off if I don't need it. Can't show you the other side because I don't want you to see any names. We're in the witness relocation program right now. And yes, that's my cheap junk grinder for at the house. My DeWalt and Bosch are on the truck. I didn't feel like using battery operated when I had outlet set in there.
