Nordyne MS3BA060KB Limit Switch
A normal limit switch is a type of sensor switch in the heat exchanger that senses, or governs, when the heated air is warmed to a point for the blower to be activated. The main reason limit switches are made is because if the air is not warm enough then the house will never get warm enough.
What are the signs that the critical limit switch is dying?
- The HVAC system refuses to kick in or continue to run longer than 10 minutes
- Your system is starting to runs spotty on more than one occasion
