Question about Dometic Rooftop RV Air Conditioner
Have not probley run this unit more than 200 hours since trailer was purchased in 2000.
This year, I turned it on for the first time this season. Trys to run cold but
cuts out and then blows warm. Its been parked in the sun in 90 plus degree weather for the last 4-5 days. Do you think it needs to be recharged? Thanks for your help.
I think you have a high pressure cutoff cycling the compressor on and off. Clean the filter inside the unit. Then with a hose clean out the foil condenser filter on top of the camper. Also you may need to buy a coil comb and comb out bent or damaged areas of the condenser coil on the unit that is above the roof of the camper.
