Question about Dometic Rooftop RV Air Conditioner

1 Answer

I have a comfort control 2200 thermostat. I changed the batteries and the thermostat is set to 80 degrees. The air conditioner stays on and the temperature on the thermostat is stuck at 80 degrees but the house temperature is down to 75 degrees and the air conditioner will not shut off unless I turn the thermostat setting to 81 degrees.

May be the location of the thermostat. Try another thermometer right beside wall thermostat & see what it reads.

Sounds like you have fan in the "on" mode instead of "auto" mode. Here's a link to download an operators manual for that system. Should help.

I have the Haier HWR08XC7 (8000 BTU) and my problem is that I have the thermostat set at 70 degrees, but it stays at 77 or 78 degrees... What could be the problem as the unit is 2 yrs old??


Hi!!

Check your owners manual, probably have unit set at automatic comfort level or some energy saver mode. It should say something on the remote about it.

Good Day!! Don't forget to rate this post!!

Thermostat location on York Diamond 90 gas furnace


Augold, sometimes its best to set the thermostat where you "feel comfortable" . I.E. set it and leave it til you feel the need to be cooler or warmer.

A thermometer on a thermostat will not always be accurate and setting it will only get it within 2 to 5 degrees which is enough to "feel".

Now from the stand point of is it working properly????

Assume you feel comfortable and the heat stays on to keep you comfortable is their anything wrong with this? I assume this is the goal. Even if it says 90 (and you know its not 90) and your comfortable you could leave it alone and be OK. If this kind of thing is whats bothering you a new thermostat may not be much better, unless your ready to invest in one and accept it however it should be closer to the place youd set it. Id recommend an electronic type they are more accurate and level doesn't matter so much to these types.

If you want to set the temperature and are determined to go by a thermometer to "feel Comfortable" I recommend you buy an electronic thermometer and set it close by the thermostat. Make sure you have no lamps or other heat sources close to the thermostat area.
Remember the far end of a room or a chair by a window Especially with little or no curtains and on the prevailing out door wind will always feel colder and be colder than the area by the thermostat even if both are in the same room. If your too cold try running the thermostat up a few degrees. If too warm set it lower. The equipment doesn't care how cold or warm it is.You will not increase your utility bills to the national debt by being comfortable

If this helps please grade me accordingly and Good Luck.
