International Comfort Products C8MPT050B12A1 Limit Switch
A normal limit switch is a switch 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. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Signs of a bad critical limit switch
- Your International Comfort Products system will not initiate or run well longer than a minute
- The International Comfort Products system is beginning to behave erratically occasionally
