Lennox 83L91 Limit Switch 320734-701 ensuring smooth mechanical linkage andThe Lennox 83L91 Limit Switch is a critical high limit safety component designed specifically for Lennox furnace systems, including the 10GCS and GCS29 series. This 185 215F Auto Limit Switch functions as a fail safe by monitoring internal plenum temperatures; it is calibrated to open the electrical circuit if temperatures exceed the 215F threshold and automatically reset once the system cools to 185F. Engineered for high duty cycles in commercial and
