International Comfort Products H2A330GKA100 Furnace Door Switch
A furnace door switch is a safety feature that prevents the vent fan and ignitor being triggered to start in order to prevent injury and fire. It is important to get the part changed immediately if you can, if it is causing you problems.
What signals that my safety door switch has to be replaced?
- The HVAC system does not begin to work even when you close the door
- The switch seems to be not there
