Thought I would share an experience I suffered when my Rockwood Roo 233S Coleman A/C didn't seem to be working. The fan would blow perfectly but no cooling was occurring.
My guess was the Start &/or Run Capacitors probably had seen the end of their life, I was after all turning past the 7 year mark of use, so up to the roof I went for a closer look... The following pictures SHOULD tell the story just fine!
Cover bolts;
Naked AC unit;
Capacitor Door;
well, by George i believe THAT was clearly the problem!
I removed the mud dauber nest, with all power removed from the trailer and the AC breaker opened and the AC thermostat/control fuse pulled....the next step was for safety, shorting the capacitors (Mine actually had no charge and were already dead thanks to that pile of mud!
In the bottom of the cabinet was the problem, what I believe was meant to be a drain hole in case water got in, was a nice place for the bees to migrate inside instead;
I used some AC Duct/Foil tape because its really sticky and I cut a hole in the center of it putting some hobby screen across like so;
Stuck that on the bottom to allow the hole to still exist but keep the bugs out like this;
I just replaced my brand new caps for the old ones, one wire at a time so I could replicate exactly how it was hooked up. Tied everything back in there with the anchor strap nice and cozy. Put the thermostat/control fuse back in place, closed the AC breaker, hooked power back up to the rig, turned the thermostat onto cool and dropped the temp to the bottom AND presto-change-oh, I now have a perfectly functional AC unit again...just in time for the 90 degree Florida weather too!!
IF anyone is looking, my local RV dealer was no help at all "I will have to order those...." This IS a Florida RV dealer too, you would THINK they would have AC caps ON HAND!! ;-)
