The Lennox 56L68 relay is an electromechanical switch that lets your control board energize higher-current loads such as the blower motor, heating element, or auxiliary components. When the low-voltage control signal calls, the 56L68 closes its contacts to pass line power, giving your Lennox system safe, isolated switching between the delicate control circuit and the loads it drives.
Common signs of a failing relay include a blower or component that won't start, intermittent operation, chattering or buzzing at the relay, or contacts that stick and leave a load running when it should be off. Pitted or burned contacts and a weakened coil are the usual failure modes after years of switching cycles.
OEM matters because the 56L68 is matched to your system's coil voltage and contact ratings. An underrated substitute can weld shut or burn out prematurely. The genuine Lennox 56L68 ensures correct switching capacity and dependable, long-life operation in your Lennox equipment.
