This OEM contactor (part number HN52KC025) is the factory-specified high-voltage switching relay for the Carrier PY1REA060115AAWB packaged unit. The contactor acts as the primary power bridge between your 240V supply and the compressor and/or condenser fan motor — closing when the thermostat calls for cooling and opening when the call is satisfied. A worn or failed contactor is one of the most common causes of a system that hums but won't start, trips the breaker, or simply has no response when cooling is demanded. Pitting on the contact points, a stuck plunger, or a burned coil are all tell-tale signs it's time for a replacement.
Compatibility: Designed as the direct OEM replacement for Carrier model PY1REA060115AAWB. If you are unsure of fitment, cross-reference OEM part number HN52KC025 against your unit's wiring diagram or data plate. Our HVAC parts specialists are available to verify compatibility before you order — no guesswork required. In stock and ready to ship today.
