A furnace door switch is a safety feature that inhibits the vent fan and other risky devices from activating so as to avoid injuries. Do not waste time and have it exchanged for a new one as soon as possible if it is damaged so as to prevent something bad happening.
Major indications your safety switch on the furnace door should be replaced
- The system will not begin even when you close the door
- The switch appears as though it has been stuck
