Carrier 50ZH Limit Switch
The limit switch contains a sensor in the heat exchanger that decides if and when the air is actually warm enough for the blower to be activated. Limit switches are crucial because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Do you know if your main limit switch is failing?
- The HVAC system is unable to start or run well as it should
- The HVAC system starts to stop suddenly occasionally
