Question about Dometic Rooftop RV Air Conditioner
"If your dirty filter caused your problem,' it was because it restricted the air flow across the cooling coil. Often if the filter is clogged then the air will divert around the filter itself - and clog the cooling coil too, in which case you will need to clean the cooling coil.
The cooling coil is looped in a coil (hence the name) and is comparable to a car radiator. You will need to clean the fins (that are entwined around the coil) so that air - can flow unrestricted, over the coil.
This can usually be accomplished with a brush of some sort. Often you can use your fingers to peel the moist mat of hair and dirt off the front of the coil.
The problem (usually) is getting to the coil, because once you get to it - it generally is not that hard to clean. Your goal is make sure air flows thru the fins and over the coil - unrestricted of dirt, hair, or whatever.
Remember - many things can cause an AC unit to 'not cool' besides the filter being dirty - which is why I prefaced my answer with 'if your dirty filter caused your problem'
