OEM Lennox Contactor 3-Pole 50A 24V Coil — 19J69

The Lennox 19J69 is a genuine OEM FirstChoice triple-pole contactor rated at 50 amps with a 24-volt control coil. This contactor acts as the primary high-voltage switch in your Lennox condensing unit, energizing the compressor and outdoor fan motor whenever the thermostat calls for cooling. When the 24V coil is energized, the electromagnet pulls the three sets of contacts closed, delivering line voltage to the load.

Common failure symptoms include a system that won't start, chattering or buzzing at the outdoor unit, pitted or welded contacts that keep the compressor running even after the call for cooling ends, and a burnt smell near the electrical panel. Pitting from repeated arcing is the most frequent culprit and eventually prevents clean contact closure.

Choosing the OEM 19J69 matters because Lennox specifies exact coil voltage, contact ratings, and terminal geometry for its condensing units. A genuine part guarantees correct amperage handling and a direct mechanical fit, avoiding the premature failures and nuisance callbacks common with generic aftermarket contactors. Protect your Lennox compressor with the factory-engineered replacement.
