Friedrich VEA18K Limit Switch
The limit switch contains a sensor in the air handler that decides when the air is actually warm enough for the blower to be activated. A limit switch was crafted because if the air is not warm enough then you will never get hot air through the ducts.
What symptoms are present when the chief limit switch has a need to be replaced?
- The system is beginning to run erratically repeatedly
- The heating and cooling system will not start or run well even though max temp has not been reached
