International Comfort Products NTP6100GFA1 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that senses, or governs, when the heated air is warmed to a point for the main blower to kick in and circulate the air. Limit switches exist because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
General indicators that your limit switch will die soon
- The whole system is starting to become unpredictable more than once
- The HVAC system will not start nor will it stay running longer than 30 seconds
