International Comfort Products PYPA24GA1 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that senses, or governs, when the heated air is actually warm enough to activate the main blower. Limit switches exist due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
How do you know if your critical limit switch is not working properly?
- Your International Comfort Products system will not begin or continue to run like it is supposed to
- The International Comfort Products system starts to become unpredictable frequently
