Angry Danhard A/C Problems

I have a Danhard A/C installed by Sportsmobile. It is seldom used and when I need to use it, it does a poor job of cooling, if it works at all. After one frustrating attempt to use the system, I learned from Sportsmobile that there are two tiny circuit breakers beneath the bench seat. I found one that was out, clicked it back on and the system ran when I briefly tested it. So I thought the problem was fixed, but I never needed to run the system again for a long time. During my most recent trip, I tried to run the system again, when on ground power. The A/C ran for a few minutes and went off. Recalling the tiny CBs, I checked and one was off. I reset the CB and tried again. The system runs and cools, but for only 4-8 minutes before throwing one of those CBs again. The CB feels warm and will not reset until it cools for a few minutes. Does anyone have experience with this and know what might be causing this condition?

A good thread on Starcool is here:https://www.sportsmobileforum.com/fo...nfo-26005.html

I included a relay flowchart that was in that link. The small circuit breaker you are talking about feeds the fuse block and relay panel discussed in this thread. I would check to make sure the fuse panel is OK. The circuit breaker is supposed to be 40 amps, it doesn't appear the that individual fuses are blowing so, I would look at the circuit breaker first.

The other circuit breaker goes to your house distribution fuse panel. I believe it is also 40 amps.

If it isn't the breaker, you can follow the flowchart, and turn things on as individually as you can. That might lead you to what items might be drawing more current then expected.

If you have external 12v aux fans make sure they both are turning and are not seized. Both of mine were and caused the same symptoms as what you’re seeing. The resistance from the seized fans would trip the small breaker.

Both fans are turning, but I had that problem after taking my Sportsmobile on its first muddy road. Since then I've put a cover over the fans. The cover comes off before running the A/C.
