International Comfort Products CAC224GKA1 Limit Switch
The main reason limit switches are made is due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch has a sensor located in the furnace that can determine if and when the air is warm enough to activate the main blower.
Major signs of an unhealthy limit type switch
- The whole system begins to run inconsistently frequently
- The heating and cooling system refuses to kick in or run well as it should
