Hi all, I have two AC's on my 2005 Holiday Rambler and the rear one does not cool. I noticed earlier in the year that the heat pump stopped working as well. I believe I tried to run the heat pump i...

First, Congratulations on your Progress! Speaking just for me, an A/C is worth working on if it's not a problem with sealed system such as failed compressor or leaking lines and coils. Worth it to replace things like fan motor(s), capacitor(s) etc.
This snippet from Doug's reply above gives you a way to do a ballpark check on compressor performance.
If that compressor is running at 11 Amps, you may be back to good again. With it running, if you can reach in safely, the smaller line from the compressor should be warm to hot to the touch, and the larger one should be cool to cold. Those are your Discharge and Suction lines, respectively.
Chris Bryant, one of our other techs, has a blog post on how to do an cleaning on your rooftop A/C. Very useful and not hard to do. Right now his site/blog seems to be down. Basically, if you remove the shrouding that's under the beauty cover, clean the indoor coil and the drain pan. The outdoor coil and its fan are accessible as soon as you remove the beauty cover aka Shroud. I found it worthwhile to clean the indoor blower wheel, but that requires quite a little more dismantling. Chris didn't include that in his blog post.

IF you have the Intellitec EMS system on your RV. Turn the Genset ON. Let genset run for 30 minutes. Turn OFF all 120 appliances. Then turn on the Rear AC to HI COOL. Watch the AMP draw meter on the Intellitec remote display. IF the amp draw is NOT over 10 amps but close to 5 to 7 amps, your unit is out of Freon. If the display shows 1 to 4 amps, the compressor has not started or running. Doug
