Fan Not Working On Dometic AC. Time To Replace The AC?

[@paulshannon4576]

Now we both know. 😁 HERM, connects to the Hermetically Sealed Compressor FAN, connects to the Condenser Fan Motor COM, connects to the Contactor and provides power to the Capacitor. If the unit has two capacitors then one is the Run Capacitor and the other is the Start Capacitor.

[@hillbillyrv]

Thanks for the info Paul.

[@khonesavanhchandara7044]

I very don’t know what happened to mine right now. It run for a while and breaker trip. When I turn breaker back on. It makes hummm noise. It keeps happening like this. Should I replace a new top unit or not. Please help. If so. Do you have a video for it. Domestic thanks 🙏🏻

[@hillbillyrv]

I have several Dometic videos.

[@Imagashole]

To discharge a capacitor without a discharge tool you can just use insulated needle nose or screwdriver and cross the contacts, do it a few times to make sure. Great video!

[@hillbillyrv]

Thanks for the info.

[@daviscrt]

Great job. Thanks. Always learning something on your channel. Don

[@hillbillyrv]

I am glad Don.

[@khonesavanhchandara7044]

My camper domestic ac just give up today. I have one question Does all domestic ac unit use the same capacitor?

[@hillbillyrv]

No

[@Mike-ig2zq]

Great video! Are capacitor failures fairly common on RVs like on residentials? H for Hermetic refers to compressor being hermetically sealed. Just means airtight. Thanks again.

[@hillbillyrv]

Cool thanks.

[@larryphillips4164]

Herm. Hermetically sealed air conditioner compressor.

[@hillbillyrv]

Yes

[@robhill8894]

I have the same problem but haven't looked at mine yet. I'm betting I have the same dual capacitor for fan and compressor. It didn't make sense that both the fan and compressor stopped working. I could hear the relay clicking but nothing happening. Thanks for the tip. I'll have to open it up to see what to get now. I may just get two and go ahead and replace the one on my other ac unit.

[@hillbillyrv]

Good luck

[@redcauthen771]

Write the invoice and collect the $$$; 😊😅😊 That’s what I like about😮😮 you, practical fixes and not a lot of definitions.

[@hillbillyrv]

It helps because I don't know the definitions. LOL....go watch "My RV Works" for all of the definitions.

[@eddytouchton7850]

My AC will run then slowly stops Blowing ! I turn it off & it runs & repeats bubba ! My control box is ok and works ! I’m think it’s the Capacitor? Any ways I’m replace it & thanks for your video

[@hillbillyrv]

Good luck.

[@eddytouchton7850]

That was the FIX my BROTHER! Thank you very much!

[@hillbillyrv]

@@eddytouchton7850 You are welcome very much.

[@billhillegass946]

So where did Mrs Hillbilly have lunch ? After all someone needs to supervise .😂

[@hillbillyrv]

I need constant supervision

[@fatimael2722]

Anything I need to know ? Before I go sticking my fingers in there ?

[@hillbillyrv]

Turn the power off and be careful with the capacitors. They store energy.

[@briancole6289]

unrelated question: Is there a travel trailer cover to use during the winter while staying in the camper? Need it to cover , or have cut out for slide out too? Can't find such a thing. Maybe you can make a video of how to insulate and use a camper in the winter?

[@hillbillyrv]

Not that I am aware of. If I get a call on that, I will try to make a video.

[@jameslezak7882]

Nice video! Thanks for your time and sharing! 👍😎✌️

[@hillbillyrv]

Thanks for watching!

[@robbieeades1956]

Great video as usual. Learn alot from you, appreciate it.

[@hillbillyrv]

Awesome Robbie

[@fatimael2722]

Thanks hillbilly. A single mother with two young girls.. shut fan off cause it got cold. And it froze. Even if it's not that. I learned what it could be with ur vid. I'm getting on the roof as soon as I'm not dizzy anymore. ( health problems) . Hug Mrs hillbilly for me.

[@hillbillyrv]

Good luck and be safe.

[@mikesmith5792]

Been have trouble with dometic ac also. It will cool for a while then the fan will stop. it trips the breaker after it sits and gets to hot i guess. I got on the roof and gave the fan a kick start by manually spinning it and it would run a few hours. Then minutes. Now seconds.

[@hillbillyrv]

Fan motors go bad. Maybe yours is bad.

[@mikesmith5792]

@hillbillyrv I might just replace the whole thing with a vent. And use the portable ac you can roll around. It's in a food truck. all this heat here in Nc has everything breakin down on me

[@victorday3410]

Herm is compressor

[@hillbillyrv]

Thanks

[@5.0_foxx]

One day I went to turn the ac on and all I’m hearing is a humming sound. I replaced both capacitors and the fan still isn’t coming on. I can go up there and the fan free spins. Anything you can think of? Thanks!

[@hillbillyrv]

Hard to say without putting my hands on it.

[@5.0_foxx]

@@hillbillyrv thank you! I’m lost at what to try next and unfortunately you aren’t in my area..

[@jakewood4075]

Im currently having the same issues. What did you figure out

[@curtisd6112]

I'm sorry this is off topic but I have a question about my norcold n8xf refrigerator the freezer is working fine but the refrigerator doesn't get very cold would that possibly be the thermistor?

[@hillbillyrv]

Yes, or something else, but that is the cheapest thing to change.

lol...you too.

[@johnnelson2980]

Thanks. You are very informative.

[@madjack7979]

LOL it was in the fine print. thats where all that info is at.. Nice Video as always

[@hillbillyrv]

The fine print gets me every time.

[@KevinCoop1]

So, you have three terminals. Common is self explaining. Fan is for the blower fan of course. Herm is for hermetically sealed compressor. You really need to discharge capacitors before you start working on them. Take your needle nose pliers and touch herm to common and fan to common and herm to fan. It’s a good thing you didn’t have to replace the unit! Mrs. Hillbilly might of had a little bit of a hard time sliding it up the ladder!

[@hillbillyrv]

Shorting them like that is acceptable? It won't damage them? She does not do heights, so that would have been a problem.

[@KevinCoop1]

@@hillbillyrv It will not hurt them or you. Capacitors have a discharge count before failure. Or if they sit unused for many years. If you would like a clamp on AC/DC amp meter that will also test capacitors, let me know and I will send you a link. Around $20-$30. Kevin

[@marcuscarmouche9023]

@@hillbillyrv I discharge mine the same way with needle nose Kenny you are safe to do that just make sure the handles are insulated not bare metal. You can discharge them with your tongue like a 9volt battery too but only once! I wouldn’t recommend that method I’m sure the survival rate isn’t the greatest 😂

[@hillbillyrv]

@@marcuscarmouche9023 ha ha....it sounds fun, but I guess I won't use the tongue method.

[@laundrymanadams6105]

HERM should be the compressor feed

[@laundrymanadams6105]

Last one I did the wasps sprang at me I almost came off the roof I just saw that nest by the coil

[@MrDoug34ele]

so....love watching your vids....another way to discharge your cap is by placing your meter in voltage and touch across the contacts. Would love to come down and help you for a couple of weeks..I bet I'd Learn alot and we could show Camron how a couple of old guys can get it done....be well and stay healthy Warthog's Mobile Rv Service.

[@hillbillyrv]

Thanks for the info. When things slow down a little more I will start doing livestreams again. I would love to have you on as a special guest. Email your contact info to [e-mail] if you are interested.

[@daredeardeal7901]

So do you do this when it is still connected??

[@MrDoug34ele]

@daredeardeal7901 no!!!...take a pic of the cap so you know how things go back and remove all wires....disconnect power first...then touch the contacts with an insulated tool....

[@daredeardeal7901]

Thank you 💖 I didn't think so but wanted to make sure 😂
