International Comfort Products C9MPV100J20B1 Limit Switch
Limit switches exist due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heating area that senses, or governs, if and when the air is warmed to a point to activate the main blower.
What are the signs that the critical limit switch is almost dead?
- The HVAC system will not even start or run well as it should
- The system starts to initiate and then stops frequently
