Carrier 58STX04510012 Limit Switch
A normal limit switch has a sensor in the air handler that makes the determination when the heated air is actually warm enough that it can be circulated throughout the house. A limit switch was crafted because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Warnings of a defective main limit switch
- Your system is starting to behave erratically on a regular basis
- The heating and cooling system will not begin nor will it stay running even though max temp has not been reached
