This is the factory OEM replacement contactor (part number HN53CD024) for the Carrier PF1AEB072000AAGC packaged unit. The contactor is a high-voltage relay that acts as the main electrical switch, engaging the compressor and condenser fan motor when the thermostat sends a 24V signal. When this part fails, you'll commonly experience an air conditioner that refuses to turn on, hums without starting, runs continuously without cycling off, or shows visible pitting and burn marks on the contact points — all signs the contactor is welded shut or has failed open.
Compatibility: Engineered specifically for the Carrier PF1AEB072000AAGC packaged unit. Verify your existing contactor's pole count and coil voltage against your unit's data plate prior to ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions. In stock and ready to ship today.
