International Comfort Products NHP236GKA1 Limit Switch
A normal limit switch has a sensor in the air handler that decides when the air is actually warm enough to activate the main blower. Limit switches exist because if the warmed air is too cool then you will never get hot air through the ducts.
How can I tell if my limit type switch really needs to be replaced?
- The HVAC system will not initiate or will not stay running as it should
- The system begins to act weird on a regular basis
