Payne PG8JAA042090 Limit Switch
The main reason limit switches are made is 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. A normal limit switch has a sensor in the heat exchanger that senses, or governs, if and when the air is actually warm enough to activate the main blower.
Signals limit switch will have to be replaced
- System will not begin nor will it stay running even though max temp has not been reached
