International Comfort Products TCA218AKA1 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that determines if and when the air is actually warm enough for the air to begin normal home circulation. A limit switch was crafted because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Signs main limit switch will need to be replaced
- The heating and AC system will not start or run for any length of time
- The HVAC system is beginning to runs spotty time after time
