Lennox G40UH-60C-110 Limit Switch
The limit switch is a switch in the heat exchanger that senses, or governs, when the heated air is warm enough for the main blower to kick in and circulate the air. Limit switches are crucial because if the air is not warm enough then the house will never get warm enough.
Indications limit type switch is going out
- System is unable to start or will not stay running even though the desired temperature has not been attained
