I have a 2012 Keystone Cougar X-lite. The past week when I turn the furnace on it runs until the desired temp is achieved. After that, nothing. I can turn the t-stat off, wait for the click, turn it back on and it runs again until desired temp. Then off again. Any suggestions as to what the issue may be? Thanks in advance.
Dose your Thermostat include a "program" mode? If so the time does not sync up with the current time and will not allow the furnace to come on! Deactivate the program mode by depressing "program" for 5 or more seconds, the program mode light should go out! You then should be able to operate your furnace without a hitch!
