Mitsubishi MS12TN Limit Switch
Limit switches are crucial because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the heating area that senses, or governs, when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Signals of a deteriorating limit switch
- Your system begins to shut down unexpectedly more than once
- The heating and cooling system refuses to kick in or continue to run as it should
