Limit switches exist due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the air handler that determines when the air is warm enough for the blower to be activated.

- Your Goodman system is unable to start nor will it stay running like it is supposed to
