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.

You can get new A/C or pulled from newer Motorhomes for less that $800 on Ebay every day.. why repair and repair when NEW is always better.. And they can not be recharged unless you want to put more money in then than they are worth...

may also be a bad start capacitor for the compressor.

Trouble is, younstill need to have the leak resolved...knowing how to recharge it is no use if you can't fix the trouble.

How old is the unit that went out? Have to agree, it might be better to bite the bullet and get a new one. Especially if it has some age on it.

I do hvacr service and it takes soooo much equipment and time to do things the epa way. It was much faster, easier and cheaper to do repairs before 88 and it was very common to have the small stuff fixed. It's bad enough dragging all the equipment around when there is plenty of room to work around a unit but working on RVs absolutely sucks. I did a lot of it when I worked for a small contractor in 05. You might be able to find a service co. that's geared for the small stuff like window bangers and rv ac but it's almost as expensive to get into one of those little systems as the bigger systems, thanks to the epa. I'd rather work on the 100 ton RTUs where I work. Craig

You should be able to find a new one for a little more than $450 or a power saver model for around $650...

With only the fan running, push the switch over to A/C with the temp controller at it's lowest setting. Afterwards, if you hear a change in pitch, like a low hum, but the compressor isn't coming on and no cold air; I would change out the motor start capacitor before replacing the unit. A capacitor will only run you around $15.

If nothing happens after switching over to A/C, then get the multimeter out, pull the plenum off the ceiling and start troubleshooting the circuits. Could be the control relay that starts the compressor is not getting a signal from the controller, freeze protection thermistor is stopping the compressor from coming on, etc....
