Trane blower door interlock switch for XL90 furnace
TRANE BLOWER DOOR INTERLOCK SWITCH FOR XL80 AND XL90 GAS FURNACES FROM THE LATE 1980'S AND EARLY 1990'S. This switch is mounted behind the door to the blower compartment and it is used to cut off power to the furnace if the blower door is removed. It is a saftey switch. It is mounted in a metal bracket with a metal arm that is depressed by the blower door. It is essentially a large micro switch mounted in a metal bracket. I has 2 holes on the top for mounting screws. I am a semi-retired HVAC contractor who is selling off his remaining inventory.
