Lennox 14ACX-042 Limit Switch
Limit switches are built because if the air never warms up then the house will never get warm enough. The limit switch has a sensor in the heating area that decides when the heated air is warmed to a point to activate the main blower.
What red flags are there that my limit switch is not working properly?
- Your Lennox system refuses to start or will not stay running as it should
- The Lennox system is beginning to behave erratically repeatedly
