Comfort Control Thermostat

We just purchased a 2003 National Dolphin. The furnace comes on when you set the thermostat but it doesn’t shut off when it reaches temp. Is the thermostat bad or is there something else we should check? Thanks!

16. SYSTEM RESET
a. Turn the ON/OFF switch to “OFF” position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to “ON”.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released

Always try this first. Batteries run low, disconnected, sometimes just Murphy, and sometimes you do nothing and it gets a glich.

Let us know if it works or if you need more help.

Hi ! Welcome to IRV2! We're sure glad you joined the gang!

Remember that when the furnace reaches set temp and turns off, the fan will continue to run for a while until everything cools down inside the furnace! Have fun and keep her between the ditches!

Good luck, happy trails, and God bless!

Yes I realize that. But the temp kept going up. The furnace was still running. But thank you for the reply!!
