Lennox 13ACX-018 Limit Switch
One big reason why limit switches are designed that way 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. A normal limit switch is a switch in the heating area that senses, or governs, when the heated air is warmed to a point for the main blower to kick in and circulate the air.
Key indicators that my critical limit switch is crapping out?
- The heating and AC system is unable to start or run like it should
- The system begins to behave erratically often
