International Comfort Products TCA236AKA5 Limit Switch
The limit switch is a type of sensor switch in the air handler that determines when the heated air is actually warm enough for the air to begin normal home circulation. Limit switches are built because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Major symptoms to watch for in a failing critical limit switch
- The heating and cooling system will not even start or continue to run longer than a minute
- The system starts to run erratically time after time
