air conditioner

My wife and I just purchased our first RV; it's a brand new 2026 Keystone Springdale classic. I have a 50 amp plug on my home so I got a 50amp diagnostic surge protector, a 50 to 30 amp step down adapter, to a 30 amp extension cord, down to the 30 amp power cord that came with my 30 amp camper...

Please vet the attached wiring diagram. I am planning to replace my dead 110 volt AC air conditioner with a 12 volt DC Air Conditioner which can draw up to 52A's on turbo mod. The Power Supply is AC to DC 12V 125A 1500W. The Changeover Switch is 20A. The Continuous Duty Solenoid is max 300A. I...

Hi. We are in the process of changing the air conditioner motor on our motorhome, Winnebago Era. It is a Coleman Mack 10. Would anyone have experience with this? The shaft is extremely tight, too long, as compared to the videos we have reviewed of other Coleman Mack rv air conditioners. thanks...

Earlier this year my membrane on the roof was replaced and after I got my 5th Wheel back this error started popping up on the Firefly. If I do a battery disconnect the error will go away but eventually return. The Dometic Penguin II w/heat pump I had originally had to be replaced and the...

I had an Advent a/c put on my fifth wheel to replace a worn out Coleman. Price being the deciding factor. Needless to say, I haven't been happy with it. It doesn't cool the rig down during the heat of the day to a livable temperature, unless I open the slide vents on the side of the ceiling...

Roof mounted air conditioner unit just loud hum and air blowing after in storage for a year. Help?

After 13 months or so of not running the air, when I tried to run it today (RV being in storage) it just hums real loud & no air coming out of vents. What's going on? Thanks

Hi, My four year old TT has a cracked Dolmetic air conditioner cover. I suppose I can replace it but one but has anyone repaired the plastic cover? Also, the cap on the one rood tank vent broken. Is there any difference to them? Galvanized steel should not break, but it will rust. PVC does...

I have a 2005 Fleetwood Discovery it has two air conditioners and two furnaces. The problem is the thermostat displays only zone one and will not allow me to change to zone two. I tried a new thermostat but same problem. It appears for some reason the thermostat is not recognizing that there is...

Just bought a 2021 allegro bus with the 3 air units on top but if you set the thermostat s each to 72 the front will eventually get the but the rear air will go to 65 while the center unit will be at 75 or higher. You can feel more air coming thru the vents at the bedroom area. How can I adjust...

Hi everybody, One of my two AC Dometic Duo-Therm 620215.301 (bedroom) doesn’t work. There is no DC voltage arriving to the thermostat (there is DC voltage arriving to the thermostat of the living room AC). Where could be the problem ? Is a fuse dead ? Where can I find it in my 1994 Newmar...

Our Coleman Mach 8 15kbtu air/heat pump has a locked up compressor. I want to either replace the compressor or the whole unit. Any idea on who would have one in stock and can do the work? Thanks

Good morning! I have a 2018 Winnebago Sunstar 27PE. As of a couple weeks ago, the air conditioner does nothing except make a little click when turned on. I eliminated the capacitors as they both test within limits. I eventually traced it to the incoming Romex to the controller box having no...

Has anyone attempted an upgrade install of the Furrion Chill Cube RV Air Conditioner - Ducted - 18,000 Btu - White - R32 AC on a circa 2005 National Tropi-Cal? It is my game plan to replace both of the Dometic DuoTherm 13.5k units on our RV.

Hi, My i-5 526rbs has one AC unit already. The website says it could come with 2. It also says is it has "Heat prewiring". Attached are screenshots. I tried googling, but can't understand how the heat is pre-wired. Can anyone help me please? I'd like to make sure it's ready for the winter...

Due to an electrical issue we spent 60 hours over a weekend running our generator non stop while waiting for a repair and ran 2 of our 3 air conditioners. High 90's. Yesterday we traveled about 200 miles with 2 air conditioners running. The entire time they short cycled and never really ran...

We are having problems with our Air Conditioner Unit on our 2024 Entegra Ethos 20T. We live in southwest, Las Vegas and we camp in hot weather if temperature reaches 95 outside, the air conditioner shuts off, the fan continues to run. Has anyone else had this problem??? James

Hey everyone, we acquired this MH after it sat for near 6 years. The owner was a Wiley codger who mumbled something about how 1 ac didn’t work or some such. The 4 button control on the wall was inop initially. I took it off and reflow’d the solders on the on/off switch think that might do it...

Hello, I have a 2012 Grey Wolf TT with a Dometic roof air conditioner. It is the style that just dumps the air directly into the camper. (There are no ducts) . Where the air comes out of the AC there is an airflow diverter that you can change by turning a wheel to change the direction of the...

I have a 2006 Tiffin 40 foot QDH. The bedroom air conditioner fan is working, but when I turn on the compressor, it kills the generator. I’ve looked for obstructions and cannot seem to find any. Does this sound fixable? If not, suggestions on replacement HVAC units? During the pandemic when...

I have the above a/c and it makes a loud noise when on. I was wondering if adding reflectix helps at all? My main concern is the noise since I am hoping to work out of my RV in the next month. For reference: this class C doesn't have additional a/c vents. Would love to see any youtube links...

New Member check in, thanks

Cat engine compressor not blowing cold. Where are the connections of adding freon on my 2006 Tiffin Phaeton Cat powered 350 or 330 HP

Hello: The great forum folks helped me out before so I thought I would ask for your advice. I have a rooftop air conditioner made by Airxel. The air condition seems to be running properly but it does not put out cold air. I am pretty sure it requires a top up of gas and if there is a tiny...
