International Comfort Products TCA024AKA5 Limit Switch
A limit switch was crafted because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. The limit switch has a sensor in the air handler that can determine if and when the air is actually warm enough for the blower to be activated.
Signals of a laboring critical limit switch
- The HVAC system is unable to start or will not stay running for any significant length if time
- The International Comfort Products system starts to run inconsistently occasionally
