Mount Vernon (non AE) Blower not shutting off.

Any idea what component might be suspect here? Possibly a temperature sensor?

Just started doing this last night. The blower is staying on for hours after the stove brings the house thermostat up to temperature. Its just sitting there blowing cold air.

Any tips are greatly appreciated. Thanks.

160 fan switch on the side of the fire wall...has bluish purple wires to it. Unplug one side and see if the fan shuts off.

weird. i just took the side panel off while it was running. i assumed you meant the 2 snap disks. i literally just touched one of the wires and the blower shut off. faulty snap disk?
