Lennox 97J65 Limit Switch 320735-701 Field-Selectable Voltage: Supports both 120VThe Lennox 97J65 Limit Switch is a critical safety component designed for precise thermal regulation within Lennox residential furnace units. Featuring a 150 180F AUTO temperature range, this primary limit control monitors heat exchanger temperatures to prevent thermal runaway. When the internal plenum temperature reaches the 180F cutout point, the switch opens the circuit to the gas valve, shutting down combustion while allowing the blower motor to
