Rv Roof Ac Freezing Up

If i m correct the a c pulled humid air in from outs.

Rv roof ac freezing up.

When the coil is iced over air delivery to the vents is blocked and if enough of the coil freezes up the freeze protector that serves to protect the compressor from operating with an iced coil closes or opens a circuit depending on which manufacturer s air conditioner is on the roof and the compressor quits running. The design should be able to work and drop the temp inside to at least 20 degrees below the outside air with in two hours. The way to solve this issue is to simply turn the air conditioner off when you go to bed and open the windows. This can also result from running an ac at a sufficiently low temperature for long enough.

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. 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. If it fails to open and the temperature is above 69 degrees it needs to be replaced.

It s entirely possible the switch has come loose from its mounting or is faulty. In many cases freezing up ac is simply the result of a poorly configured thermostat. In all instances every effort is made to ensure the correctness of all content on the rv doctor website. The majority of rv a c freeze ups are caused by low airflow usually due to dirty evaporator or condenser coils.

It is possible that your new rv ac is built with a cold switch. Once closed it will reopen when the temperature rises to between 61 and 69 degrees f. A simple continuity test and temperature measurement should quickly reveal the status of your freeze control device. I should not have to have a mh with so many problems and the support should be able to fix the problems quickly.

If you set your thermostat too low the ac is going to blast chilled air which will inevitably lead to over cooling and condensation. So there you are on a blazing hot day with no air coming out of the vents and no compressor operation. I believe this is a self inflicted problem caused by leaving the roof vents open while running the a c. This is true with the newer duo therm ac.
