International Comfort Products C9MPX080J12A2 Limit Switch
A normal limit switch is a switch in the air handler that decides if and when the air is warmed to a point for the air to begin normal home circulation. Limit switches exist due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
Simple warnings that your chief limit switch is in need of a replacement?
- The HVAC system will not even start or run as it should
- The system starts to run erratically occasionally
