International Comfort Products TCA436AKA1 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that senses, or governs, when the heated air is warm enough for the main blower to kick in and circulate the air. Limit switches are built due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
Subtle cues of a faulty limit type switch
- The system begins to runs spotty time after time
- The heating and AC system will not even start nor will it stay running like it ought to
