Quits cooling on hot humid days - Dometic Rooftop RV Air Conditioner


Answers :

The evaporator coil is not getting cold enough to draw the humidity out. You may need to clean the indoor and outdoor coils thoroughly. If the unit still isn't cooling right, it is probably due to a refrigerant leak in the system. You will have to to have the unit looked at by a professional if there is a leak. Leaks can be very difficult to find and very costly. Most of the time, it is more cost effective to replace it if necessary.
