Camper AC does not work at night - fan will not stay on

Hi! We've owned a 27' Prime Time Tracer for about 2 years now. We're in Florida. Last Summer we took it to Birmingham for a week in July.

We found that the AC would shut down at night. No matter what we did, it would not turn back on. After we flipped the breaker the AC would turn back on.

We found that we had to use the fan in the "on" rather than "auto" position with the AC running at night. I'd assume it has to do with humidity build up at night.

So we took it out this weekend for the first time this year in the heat. Low and behold, the fan would not stay "on" even when it was set to stay on at night.

The compressor would kick in, cool things down, shut off, the fan would shut off, then neither would turn on again.

It got very warm and muggy. I got up, changed the fan setting to "auto" then back to "on". Then the compressor and fan turned on again.

We plan to take it in, but I'd prefer to be a be more informed. Has anyone had this sort of thing happen? If so, can you tell me what the cause was?Thanks!Lori Groat (FWB, Fl)

BAD battery, low voltage or BAD converter not charging battery or frying them. If you have an inverter this is not the case.

The AC and Fridge NEED 12volt for the thermostat.If you have a low voltage situation the thermostat will not work.

Had the same thing happen to me. I Had 4 repair guys running in circles telling me I needed a new AC and a new fridge.:R

Both Would come on cool and then later in the day not related both would not work.

AC will come on and then when it reaches the temp set, it shuts off, BUT it can NOT turn back on because of low or no 12v to the AC. "Thermostat" needs 12v to function.

I bet if you check your fridge is not working right either.

Took me 4 service calls until I found an RV Mobile Repair guy that KNEW WHAT HE WAS DOING. He went right to the converter and checked it's output. In my case it was frying the batteries.

New converter, new battery and my "you have to replace the AC" works just fine. And the fridge.
