Are Dometic RV A/C Motors Intentionally Bad?

[@highdesertrunnerrunner418]

I thought my motor was bad (brand new Penguin II). After watching your video I realized there are two fans on the motor, I inspected the inside fan and found the two screws from the manufacturer were never tightened down so the fan was rubbing on the plastic housing (very wabbly too). I tightened the screws, move the fan a 1/4 out, straightened it and bam we have AC in the front now. I also avoided having to go into the shop for warranty repair! Thanks for the great videos!👏🍻

[@sambuvca22]

These low quality motors have to be oiled regularly. I’m a plumber buy trade but spent 10 years in south Florida doing ac service as well. I’m getting into all these repairs on my camper and you definitely have the best vids on the tube. You know what your doing for sure.

[@CajunWolffe]

Great, I just bought a new Dometic 15K BTU for my little Mallard Class C. Brisk Air II mfg. Date Nov. 2020. I got it from a dealer in Fort Worth for $750 shipped to my door. I haven't installed it yet, fixing the roof, and am now waiting on new vents; I want to first paint it with "Henrys." They are light; I'll give them that. The one up there now still works fine, and I don't know what BTU it is; these Mallards were built in Ohio, but it doesn't cut it in Houston during summer; it was a 100 in the shade today, I think. But, for an A/C that's 33 years old, it tries. Love your videos; I've learned a lot in the past 6 months!

The motor stars 4:16 horrendous noises without failing Its the sealed for life bearings is what fails. I repaced the motor in my 2014 Coleman branded unit and went from barely able to hear the TV at full volume ,to near silence 67db . I followed the directions many have posted on how to make sure the air is traveling along the ducts. I keep the air dump in the unit closed.

I can home and boom oven. I knew this was coming so I had steady had the motor. Found your video and followed it verbatim. I’m now sitting in the ac. I really appreciate the knowledge.

mostly look for AC power at the contacts to the motor on the board, if you have power and no spinning, likely the motor is bad.

[@johnnyebony9038]

2 questions: can just cut and wire nut the wires and what brand motor should I buy?

[@cashmiller2999]

I have a 13.5 domestic unit on a year old trailer and the compressor only runs for about 4-8mins. Compressor just shuts down and I can only make it go on by continually trying to turn in on/off on the thermostat. The fan works every time and every speed. When the compressor is running, I do feel cold air. At least a 20 degree difference I have checked capacitor it reads 48.5/4.7 and it’s a 50/5. And says it’s plus or minus 5 percent. So I think it’s ok Do you think it could be a faulty thermostat? It’s the soft touch kind. I can only test ac with harbor freight 3500watt generator, and when compressor is running the generator shows about 17.5 Amps Thanks for doing these videos. You have no idea how much they help!

Hello, great video. I replaced my fan motor and only low speed would work. I figured I got a faulty motor with a bad high speed winding, so I returned it and got a new motor...same issue. What would cause no high speed? Could it possibly be two bad motors from the factory? Would a bad capacitor cause that? Please help before I try a 3rd motor😁☹️

[@timdoom4432]

Well, fan motor number 3, still no high speed. New thermostat, still no high speed. Can it possibly be the capacitor? It worked fine before motor swaps.

I changed both capacitors last summer with oem.. The other day my system just gives one click and no start when I trip the Thermostat. Is there a way to test the motor with direct power? I spun the fan manually and it spins but did notice shaft moves up and down and Residue on shaft.

[@AZExpert]

If it clicks and the fan doesn't run, I'd check the 120vac breaker first, if the fan motor is getting hot and humming, then there is an issue for sure.

[@CarlLoop]

@@AZExpert Turning on fan only, just clicks at the unit. Turning on the AC with fan on Auto, just hums at the unit. New 60 + 5 capacitor, old one was good too I found out.

[@scotthicks8338]

Was the original motor a genteq? I didn’t catch that. The reason I’m asking is because we sell them for AC blower motors as replacements for OEM motors that burn out. I’ll have to keep an eye out on them if this is a problem, maybe steer my customers towards another brand.

I've got a roof top ac , it had a for sure start cap that had blown....I replaced , and the motor would run kind of slow and stop... I tested run cap and it value was just in the verge of variance , so it seemed to work slightly but not all time , so I ordered a new one it test good. But the motor still spun slowly....but run consistently ...I went ahead and ordered a new motor thinking it might be windings....the new motor does the same ...it came with new run cap , so I've tried switching it ..no change, it tested good as well. I retested the capacitance of the start cap again just to see if it changed and it is right on the money at 7.5mfd , I started trying to isolate ...and it will run at normal speed perfectly if I disconnect the start capacitor after its started ... if I try turning on without start capacitor, it won't start up on its own but with a light spin will run just fine...I've tested this out in the previous motor as well. So this makes me believe there maybe something wrong with the start capacitor in some way that it's not discharging prooerly...I've not sure, what do you think? Am I over looking something?

[@AZExpert]

I have had a a number of these dometic motors(even new ones) have this problem, I can't figure out what's going on with them either. Thanks!

[@ckm-mkc]

Check your AC supply - specifically check for a voltage drop (should 110vac min) and the amount of amps the motor is drawing (the casing will have a label with the specs) - note: make SURE you understand how to do this safely. If your breaker has been tripping because the motor or cap drew to much current, the breaker points can become pitted, ledding to weird intermittent problems. The only fix would be to replace the AC breaker. The other thing it could be is a break in your wiring.

[@mrmudstud5980]

AZ, what brand is the better AC unit to use for replacement if needed? Thanks.......

[@AZExpert]

Although I prefer Coleman type A/C's it is usually best and most cost effective to stick to the brand you have as the t-stats and control boxes only work with the A/C manufacturer. Also, quite often the wiring harnesses are proprietary and will not work easily with another brand. They're quite sneaky!!

I had a brand-new dometic AC unit fail the same way the squirrel cage came loose and just grenaded. Rcd superstore here in Columbus Ohio installed it's and I used it less than a dozen times. They want to make me tow it all the way across town so I just hired a on-site mechanic who installed the warrantied wheel and guess what happened? It exploded again and actually threw shrapnel into the foam shroud. Dometic refused to warranty or replace the unit so rcd wants me again to tow it clear across town. I've been going back and forth with these criminals for the past year because they lied about repairing a bunch of other things. Then of course the manager gets all pissy. I was just going to take them to court but that's a real pain in the butt for this stupid thing. But dragging it all the way down there so they can bulshit me again is an equal inconvenience. The second guy I paid just to remove the squirrel-cage the first time refused to get back up there and check what he's done the second time!

By the word 'crap' in the dictionary are pictures of Dometic products. I don't know about intentional but it certainly looks like self sabotage. If Dometic has a QA department it has no staff.
