Frigidaire FRP15ETT2R0 Limit Switch
Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts. The limit switch is a switch in the heat exchanger that decides when the air is actually warm enough that it can be circulated throughout the house.
General indicators that your critical limit switch will soon need to be replaced
- System will not initiate or will not stay running for any significant length if time
- The system starts to ramp up but then stops on more than one occasion
