Coleman AC freezing up constantly?
Hello all! I posted once or twice a few years ago and got great advice. I'm wondering if anyone has experience with DIY maintenance on their rooftop AC unit. We are strapped for cash at the moment ...

If the roof A/C is icing then
1: Clean intake filters inside the RV
2: Clean evaporator coils if needed (NOTE: you have to go topside to do this but you can inspect them from below while cleaning filters)
3: Clean CONDENSER coils.. (Might as well).
4: Run fan on HIGH
5: Check for the frost sensor.. this is a probe that on SOME models is stuck into the evaporator coils, near the bottom.. I have read of cases where it was lying in the drip tray and absolutly not working.. NOTE: NOT ALL A/C's have this,, But if yours does, it should be stuck in the evaporator coils.
Side note: One of my Carrier units was tripping its 20 amp breaker.. I went topside yesterday and cleaned the condenser. So far, the breaker has held.
