OEM Carrier 1-Pole 40 Amp Contactor HN51JD026 for Model PH13NR06000GADAA

This OEM Carrier contactor is the factory-specified high-voltage switching relay for the Carrier PH13NR06000GADAA heat pump condensing unit. The contactor acts as the primary power relay between your 24V thermostat signal and the 240V compressor circuit — when the thermostat calls for cooling or heating, the 24V coil energizes the contactor, closing the circuit to power the compressor. When it fails, the most common symptoms are an outdoor unit that won't turn on at all, a compressor that drops out mid-cycle, or visible pitting and burning on the contact points.

• Specs: 1-Pole (SPST) | 40 Amp FLA | 24V AC Coil | 50/60 Hz | Includes integrated shunt | Direct OEM replacement for part number HN51JD026
• OEM vs Generic: This is a genuine Carrier OEM contactor, manufactured to exact factory contact-gap, coil-pull-in voltage, and amp-rating tolerances. Generic contactors often use inferior contact alloys that pit and weld prematurely, leading to repeat failures within a single season.
• Install Difficulty: 2/5 — Always disconnect power at the disconnect box and wait for capacitors to discharge before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire connections before removal. Swap wires one at a time to avoid miswiring.
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier PH13NR06000GADAA heat pump condensing units. Always verify your existing contactor's pole count (1-pole), amperage (40A), and coil voltage (24V) against your unit's data plate before ordering. Have questions about fitment?
