OEM Carrier 2-Pole Contactor 40A 24V Coil for Model TCHC0250HEFMRAF132

This is the genuine OEM replacement contactor for the Carrier TCHC0250HEFMRAF132 system, factory part number HN52TC040. The contactor is the high-voltage relay that bridges the 24V control circuit to the high-voltage compressor and condenser fan circuits. When the thermostat calls for cooling, the 24V coil energizes and pulls in the contacts, sending line voltage to the compressor. When this part fails, the most common symptom is the outdoor unit simply not turning on — even though the thermostat is calling and the air handler is running — or intermittent cycling caused by worn or pitted contact points.

  • Specs: 2-Pole | 40 FLA (Full Load Amps) | 24V 50/60Hz Coil | 240/277V switching voltage | Direct OEM factory replacement for part number HN52TC040
  • OEM vs Generic: This OEM Carrier contactor is manufactured to exact factory specifications, including precise coil resistance, contact gap, and silver-alloy contact material. Generic contactors often use lower-grade contacts that pit and arc prematurely, leading to repeat failures within one or two seasons.
  • Install difficulty: 2/5 — Disconnect all power at the breaker and confirm voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed as a direct OEM drop-in replacement for the Carrier TCHC0250HEFMRAF132. Verify your existing contactor's pole count, amperage rating, and coil voltage match before ordering.

Frequently Asked Questions

Does this Contactor fit my Carrier TCHC0250HEFMRAF132?
Yes. This is the factory-specified OEM contactor for the Carrier TCHC0250HEFMRAF132. 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 TCHC0250HEFMRAF132?
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?
