1 Answer

Ac problems posted by couuntrygirl on Aug 20, 2008 Report abuse The unit will not cut off when it reaches it temp. in camper. I have replaced the Thermostat, control board, and the compaster on the top. I still have the same problem. It will not cut off with the switch heat off cool you have to use the hi low switch and its all wired right. Very confusing. When you move the temp control handle on the top to a different degree it makes the fan go from high to low it will not cut off. when it reaches like 70 and its set on 70 the fan will go from high to low speed. Please help me.

AC WORKS FINE HEAT COMES ON BUT WHEN TEMP IS REACHED FAN NEVER GOES OFF AND TROUBLE WITH HEAT COMING BACK ON


When temp reached to thermostat level heatewr only will cut off not the blower. And secondly all thermostat at heat stage will cut off at the end of +2 degree and cut in starting of -2 degree.

E.g; If you keep 30 degree heat it will cut off at 32 and cut in 28 degree.

Fan runs but no cool air. I don't think compressor is kicking in. Thermostat is working because when I adjust temp to be below or equal to air temp, AC unit turns on. When air temp drops as trailer cools...


Have you cleaned the unit? The condenser coil? The filter? The evapartor coil? Sounds like an airflow problem. You need to clean these areas. You can clean the condensor coil with water hose and a coil brush you can get at the hardware store. Clean the evaparator with the same brush. YOU can use a hairbrush if you don't have anything else. But make sure you go up and down on the fins on the coils not sideways. You might check your blower fan for dirt also. Good luck I hope I helped you. Could also be low on charge but first try cleaning.

No pre-existing hole to install a/c unit in rv


A roof top a/c will add about 90 to 100 pounds of weight on the roof. First check w/ the manufacturer to see if it will support the weight. If it will, you will need to cut and frame out a 14" X 14" square hole for most r/v air conditioners check the specs on the air conditioner that you will install. This can be done with a jigsaw (sabre saw). Be sure that you are not cutting into any existing wiring. Once the hole is rough cut, follow the installation instructions for the unit. You will have to have 120 volt ac run to the opening and on some models will also need 12 volt dc
