I've got an 85 Sovereign
with the original heater.
Here's the issue...I'm on my third thermostat. When I turn on the heat, it blows hot for a minute then goes cold and won't come back on. It did this before (twice), I replaced the thermostat, all worked fine for awhile, then it started doing this again so I replaced the thermostat, it worked fine for awhile...rinse, wash, repeat.
THis morning I took the thermostat off and just put the two wires together, now it is blowing nice and hot.
Any ideas? Am I just getting bad thermostats? Voltage problem to the thermostat? Problem with the control board on the heater?
Any help would be appreciated...and go ahead and assume operator ignorance on all things electrical and heater related.
