International Comfort Products NTC6075HFA1 Limit Switch
Limit switches are built because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch contains a sensor in the heat exchanger that can determine when the air is actually warm enough that it can be circulated throughout the house.
Simple signals limit switch is failing
- The heating and AC system is unable to start or will not stay running like it should
- The system is beginning to run erratically time after time
