Coleman DGAA070BDTA Furnace Door Switch
The job of the furnace door switch inhibits the fan and other risky devices from switching on so as to avoid injuries. Do not try to fix it, just have it exchanged for a new one as soon as possible especially if you think it is defective.
What red flags are there that my furnace door switch is dying?
- The HVAC system cannot run whether the door is open or closed
- The door mechanism seems to be broken badly
