Lennox G26Q3-75 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that determines if and when the air is actually warm enough for the blower to be activated. The reason limit switches exist is because if the air never warms up then you will never get hot air through the ducts.
Some warnings of a worsening critical limit switch
- The system starts to behave erratically from time to time
- The heating and AC system refuses to kick in or will not stay running like it ought to
