If you don't know how to troubleshoot, based on what you've said thus far, I think it's worth paying someone $60 to diagnose the problem for you. Someone that knows basic refrigeration and knows how to use a multimeter/read schematics can have this figured out in 30 minutes.

UPDATE!!


Update for you guys. I fiddled with the temp knob and wiggled it back and forth a coupe times, worked the on / off bottom over 20 times or so and cycled the breaker on and off 20 times and it started to freakin snow in my RV! Ice cold air, I mean ice cold.......yeah!!!!

Not sure which one it was but thanks to you guys I didn't have to take it in and pay a guy to do what I did and then lie about it and charge me $100.

Thanks guys!

My failure cost $1400 for a unit replacement. You really need to have a professional tell you what is wrong before you start doing things which could turn out to be more costly.

Good deal! Now get some contact cleaner spray and clean the toggle switch connection and hopefully you won't have a repeat.

sounds like a corroded contact in a relay or switch. just enjoy and be sure to use the switch every so often to keep it from sticking. (be prepared it may require you to cycle the switch/relay several times to have the unit come on again...
have the switch/relay replaced during the off season...

may also be a bad start capacitor for the compressor.


This is probably the problem. Open from the roof and see if one of the capcitors is blown. It would look partly melted or out of shape. Take it off (a couple of screws and nuts) and get the number. You can order them through an internet RV supply store or an RV shop. About $20.

This happened to me. Easy fix.

Good luck.

If you have good friends in refrigeration you can probably get it fixed reasonable. If you dont mgiht just go ahead buy a new one.


Fix might not have anything to do with a leak. Find a mobile RV mechanic and have him look at it.

In 2000, on an old truck camper I bought, I called the repair guy on a cordless phone while I was on top of camper with ac cover off. He said look at all the tubing, and I saw that one was broken. He went thru the whole process he would need to do to make repairs and re-charge the system with freon.

It was gonna be about $500. (no warranty)

He recommended I just get a new unit installed at the RV store, which I did for $600. (with warranty)
