LG LMU360CE Limit Switch
The limit switch is a switch in the heat exchanger that determines when the air is actually warm enough for the main blower to kick in and circulate the air. A limit switch was crafted because if the air is not warm enough then the house will never get warm enough.
Easy warnings of a barely functioning critical limit switch
- System is unable to start or run longer that five minutes
- Your system starts to act weird frequently
