This genuine OEM Payne contactor (part HN51KC024) is the factory replacement switch for the PA3ANA036000BAAA 3-ton condensing unit. A 24-volt control coil closes the contactor to feed line voltage to the compressor and outdoor fan whenever your thermostat calls for cooling. Because it cycles constantly through the season, the contacts eventually pit, weld, or chatter, producing a buzzing unit, intermittent cooling, or a system that won't start at all. This 2-pole, 30-amp OEM contactor is rated to the exact electrical load of the PA3ANA036000BAAA and restores clean, dependable switching. The replacement is well within a confident DIYer's ability and routine for any HVAC technician: cut power at the disconnect, photograph the wiring, transfer each lead one at a time, and mount the new contactor with two screws. Most jobs are done in under 30 minutes with simple hand tools. This is the authentic Payne component, not a generic substitute that may not match the coil voltage or amp rating. We ship same-day on every order placed before 3PM CST, so your AC is back online fast.
