International Comfort Products HHP442AKA1 Limit Switch
The limit switch contains a sensor in the heat exchanger that senses, or governs, if and when the air is warmed to a point to activate the main blower. Limit switches were created because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
How do you know when your main limit switch is about to go out?
- The system is starting to runs uneven repeatedly
- The heating and cooling system will not start nor will it stay running for any significant length if time
