Are Dometic RV A/C Motors Intentionally Bad?

- Опубліковано 20 сер 2024
- In the field, I have noticed that the blower motors on Dometic roof A/C's seem to have a much higher failure rate than Colemans or the Older Dometic units. I am not an engineer and have not torn the old motors apart to compare to the new motors, but I have noticed the manufacturer tags on the new motors to be coming from a different manufacturer. Here are a few musings and how to replace a Brisk Air RV A/C blower motor. Thanks for watching!!!
part number for inside blower wheel: 3313107.033
part number for outside blower blade: 3313107.015
part number for blower motor: 3315332.005
*Works so well **Fastly.Cool** for rv that it only requires daytime operation until high temp and humidity are overnight. It is difficult to get to side filters, but back is easily accessible.*
Thanks for watching! :)
This is one of the better videos in dometic motor changing.
Thank you very much!

Actually, I'm going to expound on that. Because of this video. I was able to change out my blower motor and capacitor on my domestic AC unit. I never worked on one before. This one lasted 5 years but the one before this lasted maybe 20 years. Thanxs
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!👏🍻
My blower motor went out after a years use and without this gem of a video I would never been able to install my new one. Thanks for helping me through it
Awesome!!
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.
Thank you very much for the support and encouragement. I do try to keep it interesting.
What do you recommend for lube?
@@girlnextdoorgrooming they are sealed motor bearings so they really cannot be lubed. Sorry!
@@girlnextdoorgrooming You can try spaying some white lithium grease where the shaft goes into the housing....
@@ckm-mkc If that lube penetrates, that means the seal is already gone. Trying to lube a sealed motor is pointless.
Swapped my fan motor today, using your video and another, and it is pretty straightforward. Fwiw, you don't need to mark those plug halves, it only goes together one way. Took me a little over an hour, not bad! Thanks for the video.
Excellent
Incredible video. I have swapped the cap and control module. Was about to give up. Hope this works. Thx brother
BTW, great video again. Your method of adapting the wiring into the OEM plug is a great way to simplify the installation. I’ll be emulating your process in the future. Thanks! 👍
Thank you for the praise.
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!
Thanks for watching
I will hum when I can't remember the words...another awesome video!!
Thanks again!
Thanks for the video. Was just able to replace my fan motor. We used the old fan blades. The squirrel cage was a pain to get off but with enough muscling it we got it
Good Job
Other than the mounting points looks exactly like the fan motor on my Coleman that I just replaced. I think it’s a combination of cheap bearings and the motor on the roof cooking in the sun
Great video.
Right on
This video helped me to install a new motor in my Dometic AC unit.
That's great. Im glad it was useful!
I’m in Sierra vista AZ n wow hot!! My fan blower motor went out!! Good lord trying to get someone was difficult!! Thanks for this video!!!
Yep it's a little toasty
@@AZExpert omg I just had mine changed yesterday!! Me n my fur babies r loving it!! We are hermits for today!!! Thanks for this video
I have a dometic duo therm n I just paid $700 to have a new blower motor installed n it was doing awesome then it bogged down n now it’s running but barely pissing out the vents at all n this guy is telling me I dnt know what I’m talking about n it’s running too bad what’s your thoughts!! Everything else is fine
Thanks so much, my motor started sounding like cats fighting, I did lube it and it has helped but I ordered a new motor and fans, thanks for the part numbers. Getting to be the hot season and I need both running in the 90's
Thank you for all your videos you have saved us literary thousands of dollars. If. I make it to Arizona im coming to see you and thank you personally I have construction experience but when I watch the videos you make it makes it a whole lot easier. I live in Alabama but I have a aunt that lives in Flagstaff when I go to visit her you will be my second stop. Thank you Jerry S.
thank you! I love Flagstaff!
I enjoy all of your videos, and wished you were here in Florida!
I have an older 2007 Dometic AC actually 2 of them both still going after full time use for the last 6 years, I did replace one start capacitor.
yes it's amazing how the older dometic stuff seems to be better
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. BTW cleaning the condenser and evaporator while you have access to it helps make air cooler.
Ok
So two things.
1) I hate planned obsolescence
It’s ridiculous to me that these air conditioners need maintenance after 3 years and shows me what rv manufacturers really think about their customers.
2) I work in west Texas and today it was well over 100.
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. However I probably should’ve just wire nutted my leads because that lil pin connector kicked my butt.
Keep up the good work.
it's crazy, I have never fixed an Atwood, Furrion, or Carrier A/C yet
@@AZExpert you don’t say?
Hmmm @dometic you guys suck
@@AZExpert any advice for my domestic blizzard next?
I call this video good. Well done James. Happy trails!
Thanks for watching!
Another Dometic owner here - yep, the quality has gone to crap. I had a Brisk Air that died after 20 years; replaced it with a brand new Dometic Penguin in the fall of 2018. Here we are, not even four years later... and the motor just seized up. What a piece of trash!
Yikes!
I have this same issue with mine. I just ordered a new motor and will be replacing it soon.
I'm sorry to hear that.
Very very very informative. Thank you 🙏
Glad it was helpful!
Dude really helped out thanks a bunch
Awesome!
Hello from Canada. Great job as always. I have a question about the AC motor. Is there any way to test the motor before removing it ?
Leaning the old fan and motor on the fins nice job
Did i?
I think I just found motors for two of my newer dometic A/C units, if they were really in stock. I had an idea and found company that repairs the motor online as a second choice. Just in case anyone else is interested. Dometic is out of so many repair parts right now.
Many companies are
Great video 👍
Nice job! I didn't read all the comments but I assume the fan CAP was okay? My neighbor's Dometic (Black newer unit?) fan hums and a CAP would be much easier (and cheaper) to replace than the fan motor. I'll help him either way. thank you
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! I'm sick to death of American companies that just screw their customers. I'm also sick to death of the idiots running this country into the ground using stuff made by our sworn communist enemies.
Never buy an RV if you expect to save any money unfortunately. Sorry you are having such a bad time of it
Great Video, question? What’s your thoughts on a DOMETIC AC that blows cold and runs great for 20 minutes, then a buzzing sound occurs and it won’t cycle again?
Yep just bought a new one an fan motor is ought used ac 1 weekend trip
Just attach a string to the wire and then pull wire out of black wire cover, attach new wire to tied end of string and pull string to install new wire through old wire cover.
LOL thanks for the tip
Great video again as usual! My rear Duo-therm 620525 ac fan motor is a gonner on my 2005 Newmar. I did spray with wd and got it to work for now. I hope it is as easy as yours to replace the motor? My motor is a 1/4 HP, can I use a 1/5th HP? I noticed my motor was made in Mexico. Yours was China. I will call Demetic tomorrow. Did you get yours from Dometic? Anyway thanks again for the insructional videos. Gotta probably do the front ac as well. Jeez its always something.
Thanks, I wouldn't have bee able to replace my motor without this video.
One question though.
Now my AC runs for about 5-10 minutes, stops for about 30 seconds then starts back up for another 5-10 minutes. Its not a big deal but im worried that it might be a sign of a more serious problem.
Do you have any advice?
Just to be fair you should do the same for a Coleman a/c. I think you will show Coleman uses the same type of highly engineered shroud. I’ve had to replace Coleman motors too. My Dometic units get colder and so far have lasted longer.
RVP/Coleman has their own set of issues for sure. I think Dometic had a sweet spot of longevity pre-2004. I'm kind of excited to see how long Furrion will be staying in the market. Thanks!
Thank you so much that's what happened with mine too and that makes me so mad at the corrupt manufacturers that sell us poor quality shit for a lot of money as if people living in their 5th wheels have a lot of money to begin with... (Commy Bastards)
Thanks for watching! :)
Did you do a video on how to bypass the circuit board and just make the fan and the compressor run continuously so when somebody's out and screwed and doesn't have AC on a weekend that they can have at least a temporary fix
My ac is still blowing but it's not cold it a dometic from 1986 I think it might need Freon added but I don't think they make it anymore what do you suggest
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?
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!
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.
Good Job!
I can’t seem to find the whole kit
Has anyone tried to replace the bearings yet? I haven’t looked through all the comments yet.
I have the same unit but mine runs for about one minute and then slows down and stops.
Piece of cake. Enjoyed this.
I'm happy you enjoyed watching!!
Think you could help? I did this and used the original fan blades. Realized one was off and replaced it. After I replaced it my unit no longer blows on high, only low. I just replaced the blower motor again and still only blowing on low, no high. Any suggestion? Thank you
make sure you have power on the black wire
@@AZExpert would that be maybe the connection to it went bad? Or it’s not seated far enough in?
Yes
I just replaced my ac fan motor, fan blade and fan wheel however it seems like the new fan blades are going in the opposite direction from the old one… I am not getting the air flow that I should and the new motor seems to be getting very hot when just testing. Any words of wisdom?
2 questions: can just cut and wire nut the wires and what brand motor should I buy?
Great video. I also have a BriskII. The Dometic thermostat just this past week shows an E5 error code. The code appears for all settings (fan, ac, heat pump and furnace). I can't find any documentation other than an open circuit. Tried what I could find on the internet. Still have the E5. Nick - any ideas. Charlie USAF Ret.
I believe that is a freeze switch code
Great info and I love the videos. Did you ever consider a head mount for your camera?
Thank you, I'm glad you love them. I have not had very good luck with any camera other than my phone unfortunately. The GoPro seems to drop audio all the time or worse turn itself off, and it's difficult to review that camera footage without downloading it first. I will try to improve my skills and setup going forward. Thanks!
Groovy shades, man!!!!
thanks, Geico didn't even pay me. lol
hey do you know the torque for those nuts?
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!
My fan failed this past week. None available. Had to replace entire unit. Dometic penguin II. $1700 including service call.
Nothing is ever inexpensive on an RV
My 21 coleman tq251 is already doing this.
Ouch! Thanks for watching!
I Have. 2019 toy hauler I purchased from private seller jus recently have the dometic digital gauge it turns on but seems like no power going to the a/c unit, all fuses are good and breakers it was working fine when I purchased it know it doesn’t due anything,
Any tips or suggestions sr
Great Video ....one question how can you tell when the motor is the problem ....because one of my AC on my Rv is completely dead ...and don't know if is the motor l already change the circular start capacitor but nothing ...
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.
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.
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.
@@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. Fan spins ok, not totally free and fast though... Thoughts? 🙂Yes, fan motor is the Genreq manufacturer. Dometic DuoTherm Brisk II 15K (ac only, not heat). Unit is 3years and change old. Thank you for the fantastic video!
My 2018 camper has a dometic brisk air 2 im assuming, lowest fan setting it squeaks! Should i just go ahead and replace the motor? Im in Las Vegas, so better sooner than later LOL
does it squeak at start up and shut down or constantly?
@@AZExpert No it does not, only sometimes. After seeing you tear apart this, i have a feeling the squirrel cage maybe rubbing on the foam occasionally. Gonna tear it down today.
As an auto tech I would probably just replace the bearings for $10 total instead of buying a new motor, since it’s age and not use that caused mine to fail.
I save money where I can but sometimes the labor rate isn't worth it to a customer
I have trouble deciding which is worse, Dometic’s AC units or their customer service.
Yeah...
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. And if you need warranty assist just buy a replacement because Dometic is like health insurance companies; their corporate goal is to deny, deny, deny.
I think most warranty plans are like that
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😁☹️
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.
Just changed the control box, still no high. Any suggestions?
Where located the fan motor?
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.
the original is genteq yes just like the replacement. I don't know of another direct replacement brand. Thanks!
My son did what u told him to do, but it did work but it stop blow cold air now blow hot air he need some help man.
I think my motor in my dometic
a/c is out....I have a 1978 dogde sportsman brougham c class ..come fix mine in Payson someday..I bought a 500.00 Whynter internal dual hose AC/heater unit....it works well..
But want to fix the rooftop ac before I sell it someday..any suggestions on who can look at it ..troubleshoot it??
I would recommend a completely new A/C and control setup if your a/c is 40 years old. I don't think anyone would try fixing a unit older than 5 years. Thanks!
Having trouble finding the 9 inch condensor fan. The kits all come with 10.5 inch fan. Any suggestions?
Finding parts has been very difficult for the last year. I had the same issue with a penguin dometic recently
@@AZExpert Thank You!
I just trimmed the metal fan shroud with some tin snips and it fits ok now.
And again fwiw, the cover is sooo feckin brittle along the rear opening, beware!
AGREED
Did you have to discharge the capacitor? If so, can you show and tell how? Thanks for the videos. Geeze you think a guy could make a living doing all these repairs down there. 🤝🔨🛠
I've never found a need to discharge a capacitor, they self-discharge fairly quickly, but do remove 120vac power before removing the capacitor wiring
@@AZExpert I was on the fence and thought that the charge dissipated quickly, thanks for the reply.
I live in SW FL. I have a white fishing hat with a flap that covers my neck.
I never wore hats for years and really wished I did in hindsight, especially in the Arizona heat.
AZ, what brand is the better AC unit to use for replacement if needed? Thanks.......
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!!
AZ Expert Thanks, good point on the wiring harness, in fact, that does make sense. But, of course, the competition between the companies are never in the customer interest 😳.
Carrier. AirV is the best ive ever used
Want to like twice
thank you
where do i buy one
The AC? Online
Dometic has gone to crap last couple years, replaced tons of the newer potted boards in the atwood wtr htrs , all china made junk lately
I've been surprised by the number of new water heater boards too. Glad it's not just me
Are you in Arizona and do you have a phone number I need some repairs immediately
I'm not taking any new work right now
Without a working AC an RV is a huge money pit, worthless piece of junk that’s no good to anyone in warm weather.
that is true
Yes
