Desa R40 Limit Switch
Limit switches are built because if the air never warms up the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the heat exchanger that determines when the heated air is warm enough for the blower to be activated.
How can I tell if my chief limit switch is almost dead?
- The heating and AC system refuses to start or run longer than 30 seconds
- Your system starts to runs uneven more often than not
