Goodman GSZ Furnace Door Switch
The furnace door switch is a safety switch which stops the fan and ignition sequence from turning on so as to stop a potential explosion. You should have the switch be traded for new one immediately if you can, if you see that it is broken.
What warnings are present when my safety switch on the furnace door is about to go out?
- The system does not begin to work even with the door closed
- The door switch seems fallen off

Before buying or purchasing, do your due diligence and double check the model number as well as make a visual inspection in order to be sure the correct furnace door switch is the one being purchased. You do not need to install the replacement part alone. Consult with a professional in your area to replace the part.
Feel free to download your manual for help.
