Gas Furnace keeps running after the targeted temperature is reached
We have already replaced the thermostat
To test the thermostat just disconnect the white (W) wire at the furnace. If the furnace burner stops running then you know it is the thermostat since it is still calling for heat after the set point..
How much longer does it Run... This is important....
Uh oh 0.0 that's no good.anyway, sorry can't help ya. Have a good day though and merry Christmas, hope you get that fixed :)
