Mitsubishi MSY-A24NA Furnace Door Switch
A furnace door switch is a safety feature that blocks the blower and gas ignition from activating so as to stop a potential explosion. You must have the device exchanged for a new one immediately if you can, if you see that it is broken.
Easy warnings of a poorly working safety door switch
- The furnace door switch seems to be not there
- The furnace will not even begin to start whether the door is open or closed
