Hi All:

I have a Gibson KG6RC Series. The blower fan continues to run after the thermostat temp is met. I read about limit switches etc. I am not sure where the limit switch is located on the KG6RC Series.

The thermostat is new, but this problem started before the new thermostat was install in the heating season.

Any ideas? I checked all the wires for shorts.

Sounds more like a fan relay rather than a limit switch. How old is the unit? Sure the fan switch isn't set for ON?

2007 unit. The thermostat is set to Auto (fan).
