Since we hadn't heard anything from RV Lifestyles about the compressor for the air conditioner, we called and found out they'd received a request from Coleman earlier in the week to do some more testing. Needless to say, we were more than a bit put out that they hadn't called us as soon as they'd received the request from Coleman.

We took the Excel down to RV Lifestyles so that they could do the required testing. While they were doing that, we had lunch at Silly Al's.

Turns out it isn't the compressor at all, but the "little black box" -- some kind of controller. Of course, it was too late today to contact Coleman, so it won't be done until Monday.
