OEM Carrier Contactor Replacement for PH13NR042000AFAA Condenser

The contactor is the electrically operated switch that energizes your Carrier PH13NR042000AFAA condensing unit every time the thermostat calls for cooling. When the 24-volt coil pulls in, its contacts close and send line voltage to the compressor and condenser fan motor at the same time. Because it cycles thousands of times each season, it is one of the most failure-prone components in the outdoor unit. When a contactor fails you will often notice the outdoor unit going silent while the indoor blower keeps running, a loud buzzing or chattering at the unit, the fan and compressor refusing to start, or pitted contacts that weld shut and leave the system running nonstop. Ants and debris lodging in the contact gap are a frequent cause of no-cool calls. This is a definite-purpose contactor with a 24V coil rating matched to the Carrier control circuit and silver-alloy contacts sized for the unit's locked-rotor and full-load amperage. Genuine OEM contacts resist pitting and maintain low resistance across their rated cycle life. Why OEM matters: generic contactors frequently use undersized or lower-grade contacts that pit and arc faster, raising resistance, dropping voltage to the compressor, and shortening compressor life. A weak coil can drop out under load and chatter, hammering the contacts. Installation difficulty: 2 of 5. Tools: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to confirm coil continuity. SAFETY: shut off the disconnect and the indoor breaker before touching the contactor — line voltage is present at the terminals even with the thermostat off, and the nearby run capacitor can hold a lethal charge until discharged. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PH13NR042000AFAA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR042000AFAA Condenser?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR042000AFAA Condenser. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier PH13NR042000AFAA Condenser?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
