International Comfort Products C2A336GKA100 Limit Switch
The limit switch has a sensor in the heat exchanger that can determine when the air is warm enough so that it may be pushed through the ducts and out the vents. A limit switch was crafted because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Signals of a poorly performing critical limit switch
- Your system starts to behave erratically from time to time
- The heating and AC system will not start or run well even though the desired temperature has not been attained
