Duo-Therm thermostat
I have a Duo-Therm thermostat (serial #3107612.008 which is obsoleted)that is not functioning properly, in order to make the furnace kick on you have to put it on 90° it runs and cycles but the warmest it gets is 60°. Has anybody replaced theirs with a digital thermostat without any extra modifications I was told it would over $300 to have the thermostat replaced because it also needs an up-graded circuitboard for the AC.
Thermostat is in a 2004 Montana fifth wheel. Permanently parked
Any help will be greatly appreciated.
Thanks,
Thomas
