Nordyne E3EX-012H Limit Switch
The reason limit switches exist is because if the air never warms up 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 can determine when the heated air is warm enough for the main blower to kick in and circulate the air.
Major warnings of an unhealthy limit switch
- The HVAC system refuses to kick in or run like it is supposed to
- The HVAC system is starting to become unpredictable occasionally
