International Comfort Products C9MPD100J14C2 Limit Switch
The limit switch has a sensor in the air handler that senses, or governs, if and when the air is warmed to a point for the blower to be activated. The reason limit switches exist is 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.
What warnings should I watch out for to know if my critical limit switch is about to stop working?
- System refuses to start or will not stay running longer that five minutes
- The system begins to act weird often
