International Comfort Products T9MPD125L20B1 Limit Switch
The limit switch has a sensor in the air handler that makes the determination when the heated air is warm enough so that it may be pushed through the ducts and out the vents. Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
Major clues of a poorly working limit switch
- Your International Comfort Products system will not start or will not stay running like it ought to
- The International Comfort Products system starts to ramp up but then stops repeatedly
