I purchased a 2005 32 ft. RV. The RV came with a Dometic rooftop unit. The Fan runs and I can hear the compressor kicking on, but the air coming out is only slightly cool. Are these things rechargable? if that indeed is the problem.

Quite honestly? Roof Air systems are much like window air conditioners in your home. They are closed systems. They really have no place to leak from. Usually the best course of action is to take the ceiling bezel off and with a flashlight inspect the evaporator coils. Make sure there is no obstructions, then get up in there with a vacuum cleaner then use a cleaning foam available from Lowes or Home Depot. after you have cleaned it, if it still doesn't cool, I suggest replacing the unit. If this unit hasn't been replaced since 2005, you're probably throwing money down a rabbit hole having it fixed. The hardest part of replacing a roof air is getting it on the roof. They are very easy to replace.

Bad run capacitor or bad compressor. If you hear an occasional click from the compressor try a new run cap and then a hard start kit. Otherwise it's more economical to purchase a new unit.

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.

The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Compressor will not start but the fan runs on RV air condition unit Mod 7332B896 Coleman

If you can hear compressor try to start, then kick out, then I'd say capacitor needs replace, but if you don't hear anything (moan or groan) from compressor, then I'd be looking at a new relay, or at least testing it.

I suspect that you have a bad selector switch for the on, off, low fan, high fan operation. If the selector switch is put into the off position everything should stop completely.
