OEM Carrier 2-Pole Contactor 24V Coil 30A for Model C48A503562

This OEM replacement contactor is the factory-specified high-voltage relay for the Carrier C48A503562 packaged unit. The contactor acts as the main power switch between your thermostat's 24V control signal and the high-voltage supply feeding the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an air conditioner that won't turn on at all, a unit that runs continuously without shutting off, or visible pitting and burning on the contact points. Replaces OEM part numbers HN53CB115, HN53CD115, and HN53HF122.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30A rated contacts | 240V line voltage | Heavy-duty silver-alloy contact tips for arc resistance and long service life
  • OEM vs Generic: This OEM Carrier contactor is manufactured to exact factory specifications, ensuring proper coil pull-in voltage, contact gap, and current rating. Generic contactors frequently use inferior contact alloys that pit and weld prematurely under the high inrush current of compressor startup, leading to repeat failures within one season.
  • Install Difficulty: 2/5 — Shut off power at the disconnect and confirm zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wire connections before removal. Line-voltage terminals must be torqued to spec to prevent arcing at the lugs.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed by 3 PM local time ship same business day from our climate-controlled parts warehouse.

Compatibility: Designed and tested for the Carrier C48A503562 packaged unit. Cross-references OEM part numbers HN53CB115, HN53CD115, and HN53HF122 — all three are factory-approved replacements for this application. Always verify coil voltage and amperage rating on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment prior to purchase — no guesswork required. Order now and receive same-day shipping on in-stock inventory.

Frequently Asked Questions

Does this Contactor fit my Carrier C48A503562 — Ships Today?
Yes. This is the factory-specified OEM contactor for the Carrier C48A503562 — Ships Today. 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 C48A503562 — Ships Today?
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.
