OEM Carrier 2-Pole Contactor 35A 208/240V for Model 09DE164900

This OEM contactor (part number HN52KC053) is the factory-specified high-voltage relay replacement for the Carrier 09DE164900. The contactor acts as the main power switch between your thermostat's 24V control signal and the 208/240V supply feeding the compressor and condenser fan. When the contactor fails, the most common symptom is an air conditioner that simply will not turn on — the thermostat calls for cooling, the furnace or air handler responds, but the outdoor unit stays completely silent. A burned or pitted contactor can also cause intermittent operation, loud buzzing from the electrical panel area, or premature compressor failure due to voltage drop across worn contacts.

• Specs: 2-pole | 35 Amp | 208/240V coil | Factory-matched OEM replacement | Part number HN52KC053
• OEM vs Generic: This is a genuine Carrier OEM contactor, built to exact factory contact-gap and coil-pull-in specifications. Generic contactors often use thinner contact material, leading to faster pitting, arcing, and repeat failures — especially under the high inrush loads of a scroll compressor.
• Install difficulty: 3/5 — Always shut off power at both the disconnect box and the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter to verify de-energized contacts, and electrical tape. Photograph all wiring before disconnecting terminals. The contactor mounts in the condenser's electrical compartment and typically takes 20–30 minutes to replace.
• Warranty: 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.
