Mitsubishi MSH-09NV Limit Switch
The limit switch has a sensor in the heat exchanger that makes the determination when the air is warmed to a point that it can be circulated throughout the house. This is important because if the air never warms up the you will lose all the heat as the air flows through the ducts.
What warnings should I watch out for to know if my limit type switch really is crapping out?
- The heating and AC system will not begin or will not stay running longer than a minute
- The system starts to act differently from time to time
