We have a 2007 Itasca Suncruiser 38J. The problem that we are having is that we turn the thermostat to Gas Heat, the fan to Auto and High
and set it at about 63 degrees for the night. We then go to bed and the outside temperature goes down to about 25 degrees. The furnace will go on and off once or twice and then will not come on again. We woke up this morning with the inside temperature being in the 40s. The furnace was not running. I then turned the setting to Off and back to Gas Heat and the furnace immediately came on and heated up to the set temperature.
We took the rig to the factory earlier this month with several problems, including this one. They replaced the True Air thermostat. Normally, we use the heat pump so we haven't tested the furnace much at temps over 40 degrees but I think it works better at the warmer outside temperatures than it does below freezing.
I'm doubtful that we got a new thermostat that is defective and does the same thing as the older one did so I am wondering what the problem
can be. Has anyone else had this problem and what was done to fix it?
We are in Branson this week and it is expected to be about 21 degrees
tonight so I guess I will be getting us 2 or 3 times during the night to turn the furnace off and on to get it to heat.
Helllp....
