Carrier 50GX042300 Limit Switch
The limit switch has a sensor located in the furnace that senses, or governs, when the heated air is actually warm enough for the blower to be activated. Limit switches exist because if the air never warms up then the house will never get warm enough.
How can I tell if my chief limit switch is crapping out?
- The heating and cooling system will not even start or run like it ought to
- The whole system begins to behave erratically often
