International Comfort Products CHP236GKA1 Limit Switch
A normal limit switch is a type of sensor switch in the heat exchanger that can determine when the air is actually warm enough for the main blower to kick in and circulate the air. The main reason limit switches are made is due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
Subtle hints limit switch will eventually need to be replaced
- The HVAC system begins to run erratically often
- The HVAC system refuses to kick in nor will it stay running like it should
