RE: AC problem from hell: Now compressor is turning off.

Craig, I believe that's the first theory that covers everything. First, why did the rear bearing go out on the motor in less than two years when the first motor lasted 12? Could have been a manufacturing defect for sure. But it could have also been slightly uneven drag on the fan. On the original motor, it was the front bearing that went out and I believe it's almost always the front bearing from what I've heard. And not like this. There was no wobbling of the shaft on the first motor. It was the bearing freezing and I was able to get by with lubricating it until I got the new motor. The capacitor going out so fast is also unusual. That, I've been told, is probably related to the motor and now possibly related to the motor working extra hard. Still, it's somewhat unusual to have two problems at once. When those two were fixed, and everything seemed to be working great for over a week, what are the chances of something entirely new going wrong? And of all things, it's the compressor acting like it's going bad. That's seemingly unrelated to everything else I believe. But then I'm clearly having bad luck for some reason. I must have offended the universe or something because when my wife was bringing home a new AC for the RV, the AC suddenly went out on the truck. So there's that. Back to your theory. It's very possible that those coils are partly clogged. I've only cleaned them two or three times in 14 years and I'm thinking the last time was at least five years ago when illness got me really behind on repairs and maintenance of the RV. And I never cleaned them as you described which makes a lot of sense. So. I'll clean then as you described and we'll see what happens. I have access to a pressure washer, but it's one of those awkward borrows because they have to break a rule to loan it to me. Do you think one of those hose nossles that's supposed to mimic a pressure washer would do the job? Also, there are some bent fins. Not a lot but more than I would like. They came with the RV and I missed them (not on my extensive checklist). Should I get the tool and fix them? Note on the truck: Mechanic found a fried clutch that was not capable of engaging the compressor. He said the compressor wheel was turning freely, but not coming on. He did have a reason to suspect the compressor might need to be replaced too. So I'm now referred to the AC garage of my choice. He's new to the valley and knows the options but does not know which is best. So we're doing a work around with our other vehicle until we get back to our home base in December. The motor may be involved too. But I think I have to clean the coils to know. It's capable of running strong. It's still unclear to me why it seems to blow air into the RV at two speeds. Fast when I'm getting cold air and a bit slower when I'm not. On the electrical, I know my meter will detect continuity. Not sure on the other. I know it does a couple of things I didn't understand. So maybe. I've gotta find the sucker. That means my wife needs to remember where she put it when I left it out "too long" or I have to think like her and guess where she put it. Lord help me! I'll find it and there's a good YouTube video on checking all the electrical using a simple check list (assuming the meter does it all). Sounds like I'll be having fun in a few days once the foam arrives. Thanks so much for helping out. Bill

RE: AC problem from hell: Now compressor is turning off.

I didn't get a chance to check it tonight, but there are frequent times when it sounds like the motor is turning slower and this coincides with less air flowing out of the vents. One time this happens is right around the time when the compressor turns off prematurely. When I test the air coming out of the vent, it's still cold, but a little warmer, and there's less air moving. Maybe that's normal. I don't know. But it's possible what's happening coincides with motor speed. Got the window AC in when it was 104°. It might be the hottest day this year according to the extended forecast. I can't believe how big of wimps we've become. Sunday was 40th wedding anniversary and we talked a lot the heat and feeling old. The 2020 AC saga continues. It's a 42 mile drive to town. My wife went and picked up the window unit. She was 16 miles from home and the AC stopped working on the truck. Strange. Fortunately, we do have a mechanic nearby. Hoping it's simple. There was no indication of a problem until it just happened.

RE: AC problem from hell: Now compressor is turning off.

So here's where I'm at at and some of this info my be helpful to others. I almost missed the biggest con of them all on the very popular portable air conditioners that people love so much. The hot air going outside is inside air. Lots of negative things about that, but for an RV it's a deal breaker because they aren't close to air tight. I'd be making cold air while sucking in hot air rapidly. Another negative is they have to be 20" from anything around them. Try finding a place like that in an RV bedroom. We don't have it. The unit was small, 14" wide, but the footprint is potentially 54" by 34". So... My wife is picking up a window AC that should be easy to install and get us to the cooler months in Oregon when I can leisurely get the top AC fixed. This is funny. The only one that makes any sense to buy has all the bells and whistles I would never want. You can talk to it and tell it what to do. Some people like that. Best thing though is it has an app. You can control it from anyplace. I think that feature might help resale. Being able to turn it on before you get home sounds pretty cool. So, once I have cool air, I'll keep trying to figure out if it is the compressor for sure before buying another unit. Tonight I'll update you guys with specifics on what it's doing now that it stopped doing anything to cool the RV. Someone mention that maybe it's an issue with the new fan motor. There's reason to think there might be.

RE: AC problem from hell: Now compressor is turning off.

Phil, There may be a chance. Do you remember where the leak was? Was it associated with the lower (inside) part of the unit? Thanks.

RE: AC problem from hell: Now compressor is turning off.

Thanks Doug. I appreciate your input. There's a way to try a portable unit just for the bedroom for under $300. If we don't like it, we can sell it and go with the rooftop unit for next season. Pros: * Cools the room very fast even when scorching hot. Rooftop takes forever if you don't start it early in the day. * Better dehumidifier that can be used year round. When AC is running, almost no water collects. They cool the coils with the water and most of it is expelled with exhaust. * Super easy installation. * Extended warranty is cheap. If it breaks after 4 years, you just buy another. * With another small one in the living area, there's always a backup if one needs service. * Pretty soon they will be $199. That will be the living room unit. * I don't have to climb up on the roof to do maintenance/repair. Cons: * This one is big: the exhaust hose is 6" diameter and made to run out a window with the unit sitting away from the wall. The installation I want has it next to the wall and that may be tricky since the exhaust comes straight out of the back. It will be awkward until I know it works like we think and get it installed properly for our situation. * We lose a little floor space in both rooms. * It will probably reduce resale value if it's not a spectacular upgrade to standard rooftop. * Doing one in each room does not provide much cost savings.

RE: AC problem from hell: Now compressor is turning off.

Okay Doug, I'll try again. When leaving it on all night worked, I was thinking the same thing. It's probably the compressor. I was of course hoping it wasn't. But I have nearly 60 years experience with compressors in fridges and freezers. They go out in all sorts of unusual ways in my experience. While some last 50 years sitting in the same place and constantly running, try moving them and see what happens. Maybe for an AC unit used one season and jostled around with each move, 14 years is about all you get. I'm thinking out of the box because I've noticed that my age is becoming a factor. The less time I can spend on the roof, or climbing under something, the better. So I'm thinking of going with a portable AC for the home permanently mounted in the bedroom in a place we have where you could put a washer/dryer. The hamper is there now, lol. When we're inside, we're usually in the bedroom anyway. In tbe winter we only heat the bedroom. It would fit out lifestyle and I'm thinking with cold air traveling down, it might partly cool the living area. Do you happen to have any thoughts on the technology compared to the traditional roof mounted AC? Pros and cons? Thanks! Cavie and everyone else, please feel free to chime in too.

RE: AC problem from hell: Now compressor is turning off.

Fwiw, I did fix the errors cavie pointed out along with other errors I found. This is important. Autocorrect is in the early stages of incorporating AI. Expect lots of stuff like that as it learns to do a better job (will probably take a year or more). I've embraced autocorrect and it would be hard to turn it off because I depend on it. Often I can type two letters and it knows the word I'm typing. Amazing. But when it's wrong, it can be glaring. I duplicated this one by typing a misspelling of capacitor and it put in compressor. I believe that's what happened. I reread what I wrote after I wrote it. But the human brain remembers intent and can miss the errors. It missed about 10. The world keeps changing. Unfortunately, human nature is the slowest thing to change. DNA is stubborn but it does make adjustments faster than most think. Btw, this is my are of expertise: clinical psychology, especially as it relates to genetics. There's one thing that really helps during these times and it's human nature too: the benefit of the doubt. Remember to use it and life will be a lot less stressful. I promise.

RE: AC problem from hell: Now compressor is turning off.

Hey Montana, that's good info. Our irrigation pump would not turn on today. Really weird because it's relatively new and rebuilt by the best shop in the state. PUD is working nearby. Ranger comes out tomorrow to look at the pump. If it suddenly works, maybe you're onto something.

RE: AC problem from hell: Now compressor is turning off.

Cavie, If you don't want to be of help, please feel free to not barge in and tell off someone you don't know. Here's the link for the motor: https://www.amazon.com/2-Speed-Air-Conditioner-Motor-Replaces/dp/B07PPT5Y7P Says it replaces the Fasco. It's not an exact replacement though. They didn't say that. The bolts that attach to the bracket weren't exactly right for one thing. I hope it's okay with you that I drilled four holes. I'm a long time member of this community. But my old email address no longer works. I signed up for a new account to save time. That's one hell of a way to treat what looks like a new member. I'm glad you have so much knowledge and experience in one area. It may surprise you that most people have areas of expertise. It would be nice if you could share some of what you've got. My guess is you already know what the problem is. If you don't, all you need is a little more info. Oh well, someone else will help. Anyone want to jump in and help me solve this mystery? The AC is still working perfectly since my last report. I'm going to leave it on and see if it maintains a comfortable room temperature overnight. If I made any typos, or autocorrect put in the wrong word, please forgive me and/or Google. I swear I'm not the idiot Cavie would make me out to be. I can probably fix this with a little help. If not, I'll use what I learn to hire someone who can. While there isn't nearby RV repair in this rural area. There's easily 20 people in this valley that can fix it. I just need to find one.

RE: AC problem from hell: Now compressor is turning off.

Doug, btw, I closed up over half an hour ago and the compressor is still running. Interior is cool. Back of the unit is super hot. Pipe going to the front is ice cold. I'm tempted to let it run 24/7 until I have a better grasp on what the problem might be. That assumes it keeps working which it may not. Thanks, Bill

RE: AC problem from hell: Now compressor is turning off.

Mexicowanderer, I'm trying to avoid a serviceman on this mainly because it's 200 miles round trip to one. If it's a capacitor or relay, I'd be happy to by those parts and swap them out at this point. Both are cheap and taking a small risk of buying something I may not need is not a big concern. I just want cold air. Forecast is 102 on Wed.

RE: AC problem from hell: Now compressor is turning off.

It has minimal roof controls and a remote. Supposedly you can set the remote as a stat, but that has never been used. I'll see if I can find the manual online for how it works. We use the roof stat. It has always worked fine, but it probably is a possible culprit at this point. Thanks Doug.

RE: AC problem from hell: Now compressor is turning off.

I looked. I don't think I accidently said I replaced the compressor. What I replaced was a faulty capacitor. Good to know it's not Freon or whatever they use. And no, it's not icing up. It never has. I just realized that the compressor has been running now over 20 minutes. I'm afraid to close up though because every time I did it earlier today after getting the compressor going again, it turned off within a minute. That said, it's not been on that long once today. Stupid phobia. I'll try closing up. See what happens. It's a Coleman on a 2006 5th wheel. We're original owners and I've done all repairs on it except on big one that the factory caused and fixed.

RE: AC problem from hell: Now compressor is turning off.

It is definitely cycling a lot. It's almost like when you set the thermostat higher in the evening to maintain temperature until it gets cool enough outside to turn it off and open the windows.

RE: AC problem from hell: Now compressor is turning off.

I'll test the heat theory tonight. Right now it's just a hunch. My other hunch: when closing things up, I was moving around the other two capacitors quite a bit because the new one was a different shape and size. Maybe I damaged one of those (both originals and the big one doesn't look good). But I'm not even sure what they do. There are also a couple of relays. Electrical stuff really isn't my thing. I can fix almost anything if it's just a part replacement. But diagnosing this could be tricky for me. We're set up in a state park host site where there isn't a mobile RV repair business. If there was one, I would have probably called already.

AC problem from hell: Now compressor is turning off.

It started with a funny noise that was the rear bearing on the motor going out. There was just enough play in the shaft for the fan to nick the shroud on occasion. Bought replacement motor. Wasn't exact replacement but I got it in. It wasn't running fast enough. That was the run capacitor. Easy fix (but try to find one on a weekend). Back in business for nearly a week now. Cool. Literally. Closed everything up on top. Job well done. Drank another beer. This morning. It's over 90 early. I turn it on. Compressor kicks in. I'm all proud of myself. Then the compressor kicks off 3 minutes after it turned on. I tried various things. Same story over and over. Right now it's running but every window is open and every fan is going. It must have turned back on briefly because I just heard it turn off and there was cool air for a few minutes. I was up top earlier and none of the pipes were hot or cold like they're supposed to be. When the compressor is on, they are. Any ideas? I'm nearing the limit of my knowledge. I had replaced motor, blower fan, and capacitor before. So this time wasn't too hard. But I was kind of hoping that was all that could go wrong. Apparently not. Could it have something to do with it being so hot? Right now is the hottest so far this year at 99.
