Carrier 38HDC018 Limit Switch
A limit switch was crafted because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the heat exchanger that determines when the air is warm enough for the main blower to kick in and circulate the air.
Symptoms of a deteriorating critical limit switch
- The system begins to shut down unexpectedly repeatedly
- Your Carrier system refuses to kick in nor will it stay running like it ought to
