Haier HC42D2VAR Furnace Door Switch
The furnace door switch is a safety switch which stops the draft inducer and other risky devices from switching on in order to prevent injury and fire. Do not waste time and have it swapped out at once if it is not working in order to prevent injuries.
Key indicators that my safety switch on the furnace door is almost going bad?
- The HVAC system does not operate with the door closed
- The switch seems to be fallen off
