Trane TWR036D100A0 Furnace Door Switch
This switch inhibits the fan and ignition sequence being triggered to start so as to stop a potential explosion. Do not waste time and have it traded for new one as soon as possible if it is defective.
What are the indications that my switch on the furnace door is about to stop working?
- The door switch looks like it is damaged
- The HVAC system will not begin even with the door closed
