Mitsubishi MSY-A15NA Limit Switch
The limit switch has a sensor in the air handler that makes the determination when the air is warm enough to activate the main blower. The main reason limit switches are made is because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Chief elements of a poorly working limit type switch
- The HVAC system is beginning to shut down unexpectedly occasionally
- Your Mitsubishi system refuses to kick in nor will it stay running longer than 10 minutes
