Rv Roof Ac Freezing Up

A simple continuity test and temperature measurement should quickly reveal the status of your freeze control device.

Rv roof ac freezing up.

If it fails to open and the temperature is above 69 degrees it needs to be replaced. In many cases freezing up ac is simply the result of a poorly configured thermostat. If your rv ac is freezing up at night it means that the night air is a lot lower than that benchmark. I believe this is a self inflicted problem caused by leaving the roof vents open while running the a c.

If you set your thermostat too low the ac is going to blast chilled air which will inevitably lead to over cooling and condensation. Once closed it will reopen when the temperature rises to between 61 and 69 degrees f. This can also result from running an ac at a sufficiently low temperature for long enough. If not then why in low humidity will a ac freeze when the air flow is on high.

This freeze control is a thermally activated switch of sorts that closes once the temperature of the evaporator falls below 49 degrees f. So there you are on a blazing hot day with no air coming out of the vents and no compressor operation. If i m correct the a c pulled humid air in from outs. It s entirely possible the switch has come loose from its mounting or is faulty.

In all instances every effort is made to ensure the correctness of all content on the rv doctor website. I should not have to have a mh with so many problems and the support should be able to fix the problems quickly. 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.

This is true with the newer duo therm ac. 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 majority of rv a c freeze ups are caused by low airflow usually due to dirty evaporator or condenser coils. 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.
