International Comfort Products HPFM60K000A Limit Switch
The limit switch contains a sensor in the heat exchanger that senses, or governs, when the heated air is warmed to a point for the blower to be activated. Limit switches exist because if the air never warms up then the house will never get warm enough.
What are some indications that my chief limit switch has to be replaced?
- The heating and AC system is unable to start or continue to run as it should
- The International Comfort Products system begins to act weird more than once
