Carrier 38TPA060 Limit Switch
The limit switch contains a sensor in the heating area that makes the determination when the heated air is actually warm enough for the air to begin normal home circulation. Limit switches are crucial due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
Signs limit switch will not last the year
- The system is starting to runs spotty occasionally
- The heating and cooling system refuses to kick in nor will it stay running for any length of time
