Mitsubishi MSH-12NV Limit Switch
A normal limit switch is a type of sensor switch in the heat exchanger that senses, or governs, if and when the air is warm enough for the air to begin normal home circulation. Limit switches are crucial because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Do you know if your limit switch most likely is almost dead?
- The whole system is starting to run erratically often
- The HVAC system refuses to kick in nor will it stay running even though the desired temperature has not been attained
