OEM Carrier 3-Pole Contactor 24V 60 FLA for Model TCHC2550HECMRMH500

The Carrier HN53TZ024 is the factory-specified 3-pole contactor for the TCHC2550HECMRMH500 commercial packaged unit. The contactor acts as the high-voltage relay that closes the circuit to the compressor and other high-draw loads each time the thermostat calls for cooling or heating. When the contactor fails, common symptoms include the unit failing to start entirely, audible chattering or buzzing from the control panel, burnt or pitted contact tips visible on inspection, or the system tripping breakers due to a welded-contact fault. This is a high-cycle component in commercial applications and one of the most frequently replaced parts in the field.

  • Specs: 3-Pole configuration | 24V 50/60Hz coil voltage | 60A FLA (Full Load Amps) | 75A RES (Resistive) | Factory OEM part number HN53TZ024 | Weight: 1.49 lbs
  • OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory tolerances. Generic contactors often use substandard contact alloys that pit and weld prematurely under the high inrush current demands of commercial compressors — accelerating failure and risking downstream damage to the compressor itself.
  • Install difficulty: 3/5 — Requires full lockout/tagout of all power before service. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire labels or smartphone for wiring documentation, and a multimeter to verify coil continuity and contact resistance after installation. Always confirm 24V control signal at coil terminals before replacing additional components.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier TCHC2550HECMRMH500 commercial packaged HVAC unit. Also fits related 50HECMR and 50HECMRA series models — verify your model's data plate and existing contactor pole count and coil voltage before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier TCHC2550HECMRMH500?
Yes. This is the factory-specified OEM contactor for the Carrier TCHC2550HECMRMH500. 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 TCHC2550HECMRMH500?
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?
