Question about Dometic Rooftop RV Air Conditioner
The AC (Duo-Therm Model 57915.622) in my RV has been working great until today. All of a sudden, the compressor would sound like it was kicking on, but then just hum for a few seconds, and then kick off. When this occurred, I can smell a slight electrical smell coming out of the AC vents in the ceiling. About 10 seconds after the compressor kicks off, it tries to kick on again and repeat the same cycle.
Sounds like your start capacitor may have gone bad. If you remove the shroud, there should be an access panel for the electronics. In there, you'll see one (or two) cylindrical parts with wires coming out the top. If one of them shows signs of something coming out of it, it's probably your start capacitor and it needs to be replaced.
You can view the installation/service manual for DuoTherms here at Bryant RV.com (it's a 3MB PDF file, so download with care). Look on page 28 for info on the capacitors.

Something has gone wrong and needs to be repaired. It's an electrical problem. The more you smell it, the more stuff is getting burnt. Take it apart and look inside it. Then restart it. The burning stuff will lead you to the bad part.
