Goodman ARUF303016 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that can determine if and when the air is warm enough for the main blower to kick in and circulate the air. This is important because if the air never warms up the you will lose all the heat as the air flows through the ducts.
Some warnings limit switch needs a replacement ASAP
- The Goodman system is starting to act differently on more than one occasion
