Mitsubishi MSZ-A09NA Limit Switch
A limit switch was crafted due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts. The limit switch is a switch in the heating area that decides if and when the air is warmed to a point for the main blower to kick in and circulate the air.
Do you know if your limit type switch really is failing?
- The HVAC system refuses to start or run even though the desired temperature has not been attained
- The system is beginning to go through the startup sequence but stops quickly more than once
