International Comfort Products PGMD36G0606 Limit Switch
Limit switches are crucial because if the warmed air is too cool then the house will never get warm enough. A normal limit switch has a sensor in the heat exchanger that makes the determination when the heated air is actually warm enough for the air to begin normal home circulation.
Major clues of a failing limit switch
- The HVAC system will not even start or continue to run even though max temp has not been reached
- The International Comfort Products system starts to runs spotty occasionally
