Brand new rv ac freezing up. This freeze control is a thermally activated switch of sorts that closes once the temperature of the evaporator falls below 49 degrees f. This is true with the newer duo therm ac. Your air conditioner is low on freon.

It is possible that your new rv ac is built with a cold switch. The way to solve this issue is to simply turn the air conditioner off when you go to bed and open the windows. So there you are on a blazing hot day with no air coming out of the vents and no compressor operation. Once closed it will reopen when the temperature rises to between 61 and 69 degrees f.

The majority of rv a c freeze ups are caused by low airflow usually due to dirty evaporator or condenser coils. I believe this is a self inflicted problem caused by leaving the roof vents open while running the a c. Even in high ambient temperatures. This can also result from running an ac at a sufficiently low temperature for long enough.

If it fails to open and the temperature is above 69 degrees it needs to be replaced. If either set of coils is dirty the air conditioner needs to work harder to cool the air and transfer heat out of the rv. A crow bet that the dealer finds nothing wrong with the ac. A simple continuity test and temperature measurement should quickly reveal the status of your freeze control device.

The coils in your air conditioner unit evaporator coils and condenser coils need to be cleaned regularly. If you set your thermostat too low the ac is going to blast chilled air which will inevitably lead to over cooling and condensation.

In all instances every effort is made to ensure the correctness of all content on the rv doctor website. Freeze ups can and do happen in high humidity.
