Rv Roof Ac Freezing Up

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

Rv roof ac freezing up.

So there you are on a blazing hot day with no air coming out of the vents and no compressor operation. This can also result from running an ac at a sufficiently low temperature for long enough. The majority of rv a c freeze ups are caused by low airflow usually due to dirty evaporator or condenser coils. In many cases freezing up ac is simply the result of a poorly configured thermostat.

It s entirely possible the switch has come loose from its mounting or is faulty. 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. It is possible that your new rv ac is built with a cold switch.

I should not have to have a mh with so many problems and the support should be able to fix the problems quickly. 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. If your rv ac is freezing up at night it means that the night air is a lot lower than that benchmark. Brand new rv ac freezing up.

This is true with the newer duo therm ac. If you set your thermostat too low the ac is going to blast chilled air which will inevitably lead to over cooling and condensation. If it fails to open and the temperature is above 69 degrees it needs to be replaced. The coils in your air conditioner unit evaporator coils and condenser coils need to be cleaned regularly.

The way to solve this issue is to simply turn the air conditioner off when you go to bed and open the windows. I believe this is a self inflicted problem caused by leaving the roof vents open while running the a c. Once closed it will reopen when the temperature rises to between 61 and 69 degrees f. 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.
