Lennox 78W99 Limit Switch 319847-401 Is the capillary tube field-extensibleThe Lennox 78W99 Limit Switch is a critical safety component engineered to regulate heat exchanger temperatures within Lennox G40, G41, G50, G51, and G61 gas furnaces. This L235 30F thermal limit control features a fixed temperature setting, designed to open the electrical circuit at 235F and automatically reset once temperatures drop by a 30F differential. Precision calibrated for high limit protection, this SPST (Single Pole Single Throw) switch
