OEM Carrier 2-Pole Contactor 24V Coil for Model C48A405062

This OEM replacement contactor is the factory-specified part for the Carrier C48A405062 packaged unit. The contactor is a high-voltage relay controlled by your thermostat's 24V signal — when it receives the call for cooling, it closes its contacts and delivers line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioning system won't turn on at all, hums without starting, or trips a breaker repeatedly. Burnt or pitted contacts are a telltale sign of contactor failure.

  • Specs: 2-Pole configuration | 24V coil voltage | 30–40A contact rating | Direct OEM replacement for part numbers HN53CB115 and HN53HF122
  • OEM vs Generic: OEM contactors use factory-grade silver-alloy contacts rated for the exact load of your Carrier system. Generic contactors often use lower-grade contact materials that pit and weld faster under repeated switching cycles, leading to premature failure.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removing the old contactor. Transfer wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier C48A405062 packaged unit. Cross-references OEM part numbers HN53CB115 and HN53HF122. Always confirm coil voltage and pole configuration on your unit's data plate before ordering. Need help verifying fitment? Our HVAC parts specialists confirm compatibility before your order ships.

Frequently Asked Questions

Does this Contactor fit my Carrier C48A405062 | National HVAC Parts?
Yes. This is the factory-specified OEM contactor for the Carrier C48A405062 | National HVAC Parts. 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 C48A405062 | National HVAC Parts?
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?
