Door Safety Switch Emergency Replacement
The door switch prevents the furnace from operating when the blower door is removed. A broken or misaligned switch can prevent the furnace from running even with the door properly installed.
Emergency Warning
A broken door switch prevents furnace operation. Emergency replacement is quick and restores heat immediately.
