A/C pops CB

I have a 30 ft. 1999 Excella. The A/C pops the 20 amp CB after about 30 minutes of use when the outside temp is in the high 90's or 100's It is a brand new Dometic 15K BTU. The old 13.5K BTU was doing the same thing. Any thoughts?

Yep, same AS, same problem. It appears the breaker gets hot and blows. We open the front of the breaker box, take off that plate, and have an inexpensive clip-on fan mounted to the open overhead storage door pointing at the breakers. That has seemed to keep the breakers cool enough to hold.

I was told by Terry at ODM that the old 13.5 compressor was failing, and that caused the blow. I had them install a new 15. It is quieter, and seems to work more efficiently. Still, when the inside of the AS is very hot we need our fan arrangement to get it down to cool enough. Once the inside is cooled down the breaker seems to hold.

Hope this helps.

Breakers are easy to change and new ones are inexpensive.

And those "miniature" breakers seem to be more susceptible to heat. Sal.

Agreed.

The originals in my trailers got hot. Not an issue after replacement.
