Carrier 38YCS042 Furnace Door Switch
A furnace door switch is a safety feature that inhibits the draft inducer and other risky devices from turning on so as to stop a potential explosion. You must have the device exchanged for a new one as soon as you can if it is not working in order to prevent injuries.
What warnings are present when my safety switch on the furnace door is failing?
- The system does not function whether the door is open or closed
- The safety door switch looks like it is bent badly

Before buying or ordering do your best and cross-check the model number and also make a visual comparison in order to be sure the correct replacement furnace door switch is being ordered. You do not need to install the replacement part alone. Locate a pro locally to do it for you.
Feel free to download your manual for help.
