Thermostat challanged

[treeplanter]

Atwood 7916-11 furnace comes on with thermostat in run position. Will not shut down regardless of temperature position. Waited 5 min +-. Purchased camper used, furnace never been used, only 2 years old.
Doesn't this have to be a thermostat issue?

After taking a break from it I took another look. The contact was stuck. Cleared and cleaned ,everything works correctly. Thanks for the input.

Will not shut down. Clarify. Stops Heating but will not shut down or NEVER stops heating? Doug

Auto section on RV furnace/AC tstats are non functioning in furnace mode.
