Hello, new here. I have a 2004 fleetwood pioneer that the heat wasn’t blowing as hot last week and the very next day the thermostat would not do anything. No fuses blown no breakers tripped, reset all breakers just to be sure, battery is on 12.9 volts. I’m also hardwired into shore power. What could be the issue?? I also had an outlet with a fan plugged in that would run for 5 min then the fan would stop. Again no breaker tripped no fuses or gfi tripped.
