I have a prowler 5th wheel,woke up this mornig to a non-workingheat/air system checked fuses changed thermostat -still non-functioning Any suggestions??
If you have a Dometic AC, changing the thermostat involves a specific thermostat -- not a Lowes model. In my unit, it controls a relay box located in the AC which also controls the furnace.
If the new thermo did not solve the issue, I would put the old one back to be sure I wasn't adding another issue.
