No manufacturer or model number. Fan and heater coils run constantly until breaker is turned off and left off for a while. Then runs fine for awhile and does it again. Even with thermostat set to cool coils heat and fan runs. Replaced temp sensor and single double stack sequencer last fall. Thank you for any ideas. Curtis W.

Locatet the thermostat wires that come from the thermostat to the furnace. Provided this is not a heat pump and the unit is wired correctly, disconnect the white thermostat wire while the unit is heating. Wait about 4 minutes. The unit should be off by that time. If it is you have a problem with the thermostat or the wires between the thermostat and the furnace. If it continues to run after the 4 minutes with the white wire disconnected, you have a problem with a control in the furnace or a improperly wired heat circuit.
Thank you Stan will try, Curt
