International Comfort Products CAC424GKA1 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that decides when the air is actually warm enough to activate the main blower. 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.
Hints critical limit switch is in need of replacing
- The HVAC system is unable to start or will not stay running for any length of time
- The whole system is beginning to runs uneven time after time
