Question about Dometic Rooftop RV Air Conditioner
We have had our RV AC unit into 2 different dealers in the last couple of months, due to the unit running for awhile working fine then icing up and not working. No one can seem to diagnose the problem with the unit. I am not sure why but the last dealer we had it to put a piece of metal wrap inside the unit?? Charged us $85.00 and didn't fix the problem. Brought it home turned on the AC unit on low fan w/ac on for all night and it wasn't cool in the trailer in the morning.. no cold air coming out...Of course I had all the vents closed to.
RV is a 23' Salem 2002
Thank you in advance for and suggestions of what is wrong..
It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.
