Tip A/C Fan Running When Shouldn’t

[DennisT]

So, had this issue today and thought I’d pass along what I did…

Needed the heat pumps yesterday but when they both tried to start it pulled the camp power down tripping the watchdog and generator started on hvac demand.

Once that was figured out we ran just one heat pump and all was good.

Today, putting things back in cool mode the rear a/c fan started even when in auto and compressor not running.

After trying a few things at the control panel I did a reset.
- opened breaker for rear a/c
- pulled fuse for a/c controls
- after about 30 seconds replaced fuse then shut breaker

That appears to have reset the controls and the a/c is in cool mode, fan auto, and not running now.

where is the fuse for the AC controls?

where is the fuse for the AC controls?

In our Superstar it is in the bath cabinet beside the breaker panel. Labeled HVAC controls for the fuse. 7.5 amp.
