Having problems with your Air Conditioners ?
RV Roof Airs, not so cool
Low side is 65 at high speed.\015\012Have not done the temp check.\015\012It does have a clamp on port only on the low side.\015\012I hear they are prone to leaking.
After you check the pressure, get back with me. Age is always a factor with proformance. But really, unless it is leaking freon or has a defective part, the unit should work fine. Measure the temp drop across the coil. Meaning from the intake to the output. Get back with me.

Not cooling Have a Dometic 13500 roof top air cond. We are full timers in our 2004 Open Road 5th wheel. Lately the air will not cool below 81 degrees and it keeps kicking off because the compressor overheats. wait 4 minutes and it comes on again. Air is col but not cold. Have cleaned the coils, etc. Good airflow just not cold air. HELP!!!!
Check the and see if the condenser fan is running. you will find it if you take the top off also check and see if the condenser coil is clean. if it is dirty or the fan under the top is not running it will cause the compressor to short cycle on lim ... Dometic Rooftop RV Air Conditioner

My roof dometic roof top air conditioner runs but will not cool when the motor kicks on it goes right back off and will not cool

Just bought a used 1987 Real-Lite truck camper. The roof air unit is Dometic as well as the LP/AC refrigerator. When turned to "cool" the air conditioner really draws down, dims the lights, and eventually blows the home AC breakers. It works fine on blower fan only but as soon as I engage the "cool" settings, big brown out. The fridge doesn't work at all. I'm in the Nashville area. Suggestions
To start with, if it's plugged in to a 15 amp breaker, and extension cord, the compressor starting up may just be enough to trip the breaker. It will draw close to 15 amps on start-up of compressor, and if there is a light extension cord used to plug ... Dometic Rooftop RV Air Conditioner
I have a suburban lp furnace and duotherm air/heat pump roof unit. duothern thermostat. 20 amp breaker kicked ( reset breaker) & furnace quit. NOW furnace fan comes on but does not light, and the front AC will not work either, when in the COOL position on STAT the unit blows warm air instead of cold. I replaced the Thermostat and a Tech guy checked the board in the furnace and it was OK. He also switched the board from the rear air with the front and nothing changed. Rear air and heat pump works

I have a 1992 Class C Gulfstream Ultra motorhome with a Dometic, Duo-Therm roof top AC system (ducted) model # 58915 and the old analog thermostat on the wall. The unit comes on and the compressor seems to be kicking in a few seconds later (just from the sound of it) but it's just blowing cool air. Not hot but DEF not cold! Do I need a new roof top unit or could there be a cheaper fix such as a known part that fails on these units? Hate to buy a whole new unit for 700 bucks plus labor if it's po

I have a Coleman roof mounted AC unit on a travel trailer. The unit model is 83338715. The unit just blows cool air not cold air like it should. I was told to replace the "Hard Start Capacitor" and "PTCR Start Device" which I did. This did not remedy the problem. Any thoughts would be appreciated. Could the problem be the "Compressor Run Capacitor"? Reason being that I hear no change in the blower sound when the unit kicks on???
Blowing 'cool air' could mean - room temperature air or it could be 'cool' because the system is low on refrigerant, and just barely doing any 'cooling' at all.\012\012To determine which is which - you need to know "for sure" if the compressor ... Air Conditioners

Coleman RV Rooftop Air Conditioner - cage fan making a noise like it is hitting on something as it goes around. The motor works as it should, low and high fan and cool, the air is cold. The only thing that is a problem is the sound. We have already removed the top from the roof and the bottom cover from inside so we can see the cage fan, but cannot see what it could be hitting. Any ideas?
Hi,\012Those squirrel cage fans have a habit of coming apart, or getting dirt in them and going out of balance...then they wobble and hit the sides of the fan housing...\012Make sure the fan is clean and also move it around a bit to make ... Dometic Rooftop RV Air Conditioner
I have a Coleman 6770 A Series roof air on my trailer. It won't blow cool air. Is this a compressor problem? And if so, would it just be cheaper to replace the whole unit than to try and repair this one?
Before the compressor is condemned, is it running at all? Is it getting the proper voltage? If the compressor will run and still does not cool the system could be low on refrigerant.A replacement compressor is normally more economical tha ... Coleman Air Conditioners

Heater not working. have power going to heating element. I,m guessing there's a heater inside of the roof air conditioner because it has a heat or cool on control panel. I belive the number of unit is QC 135 029193 0000 made by Dometic care. My RV was made in 85 made by EZ Rider. Thanks Paul
