Payne PG8JAA066110 Limit Switch
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. A normal limit switch is a type of sensor switch in the heat exchanger that senses, or governs, when the air is actually warm enough that it can be circulated throughout the house.
What are the signs that the critical limit switch is almost going bad?
- Your Payne system refuses to kick in nor will it stay running longer than a minute
- The HVAC system starts to become unpredictable occasionally
