International Comfort Products CAC260AKA1 Limit Switch
The limit switch has a sensor in the heat exchanger that senses, or governs, if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. The reason limit switches exist is because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air.
Clues to watch for in a failing critical limit switch
- The heating and AC system will not even start nor will it stay running longer that five minutes
- The International Comfort Products system is beginning to behave erratically frequently
