Having issues with HVAC; 2011 2551.
Couple of problem examples:
- Turn furnace on, it runs brings up temp, turns off, never comes on again by itself, click temp up two (one won’t work) degrees and furnace runs a cycle, rinse/repeat.
- Set thermostat to furnace and when the furnace comes on so does the AC unit. I have to turn the AC breaker off to run the furnace by itself. I have a heat strip unit but the air doesn’t get warm so assuming it’s the AC fan running.
I’ve replaced the thermostat on recommendation of Dometic but that changed nothing.
I understand there is a control unit the thermostat connects to but don’t recall seeing that the few times I’ve had the utilities compartment under the bed open.
Before I rip that all apart again can someone confirm that’s the location of the controller I’m talking about?
