This is important because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. The limit switch has a sensor in the heat exchanger that determines when the air is warmed to a point for the main blower to kick in and circulate the air.

- The HVAC system will not begin or will not stay running like it should
- The Goodman system is beginning to act weird occasionally
