This is the factory OEM replacement contactor for the Payne PA1PPB030000AAAA air conditioning system. The contactor is a high-voltage relay that receives a low-voltage signal (24V) from your thermostat and switches line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms include the AC unit not turning on at all, the compressor cycling off unexpectedly, or visible pitting and burning on the contact points inside the unit.
Compatibility: Engineered as the direct drop-in replacement for the Payne PA1PPB030000AAAA split-system air conditioner. Always verify coil voltage and pole configuration against your unit's wiring diagram or data plate before ordering. Our HVAC parts specialists are available to confirm fitment before you buy — no guesswork required.
