Mitsubishi MUY-D30NA Limit Switch
Limit switches are built because if the air is not warm enough then you will never get hot air through the ducts. The limit switch is a switch in the heating area that makes the determination when the air is warm enough for the main blower to kick in and circulate the air.
How do you know if your limit switch most likely has to be replaced?
- The heating and AC system will not even start or will not stay running longer than 10 minutes
- The whole system starts to run erratically often
