Goodman GDH80453AX Limit Switch
The limit switch has a sensor in the air handler that can determine if and when the air is warmed to a point to activate the main blower. Limit switches are built because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Key indicators that my limit switch is failing?
- System will not initiate or will not stay running longer that five minutes
