The genuine OEM Lennox 95M55 contactor controls the flow of line voltage to the compressor and condenser fan motor in your Lennox outdoor unit. When the thermostat calls for cooling, a low-voltage signal energizes the contactor coil, snapping the main contacts closed to power your system's largest electrical loads. Constant cycling makes this one of the hardest-working — and most commonly replaced — parts in the unit.

Common failure symptoms: Watch for a 95M55 that leaves the unit humming but not starting, exhibits pitted or fused contacts, chatters audibly, or fails to drop out, causing the compressor to run nonstop. Arcing, corrosion, and heat discoloration on the terminals are all signs the contactor has reached the end of its life.

Why OEM matters: Correct voltage and amperage ratings protect your compressor and fan motor from damaging power interruptions. The OEM 95M55 matches your Lennox unit's original coil voltage, contact rating, and mounting layout for a true drop-in replacement. Genuine Lennox contacts are built to withstand repeated high-current switching, offering better durability than aftermarket alternatives.
