What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model HB1CJX060000AAAA is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number HB1CJX060000AAAA.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Is this capacitor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Dual Run Capacitor & Start Capacitor for Model HB1CJX060000AAAA

This factory-matched OEM capacitor set includes both the P291-5554RS Dual Run Capacitor and the P281-8806 Start Capacitor, the exact components specified for the Carrier HB1CJX060000AAAA 5-ton residential split-system condenser. The dual run capacitor sustains the compressor and condenser fan motor during normal operation, while the start capacitor delivers the additional torque burst needed to overcome compressor inertia on startup. Common failure symptoms include a humming condenser with no motor movement, the compressor clicking off on thermal overload within seconds, or the outdoor fan spinning slowly or not at all. In humid or high-cycle-count environments, both capacitors should be inspected and replaced together for a complete, lasting repair.

Specs — P291-5554RS: Dual run capacitor | Factory-rated MFD and 370V/440V voltage | Round case | ±3% tolerance | Compressor + fan terminals (HERM, FAN, COM)
Specs — P281-8806: Start capacitor | High microfarad burst rating | Matches factory start assist specification for HB1CJX060000AAAA compressor | Includes bleed resistor for safe discharge
OEM vs Generic: OEM capacitors from Carrier are wound to exact factory tolerances. Generic replacements commonly ship at ±10% MFD variance, which increases motor winding stress, accelerates compressor wear, and can void equipment warranties. For a 5-ton unit cycling under heavy summer loads, factory-spec capacitance is critical.
Install difficulty: 2/5 — Always discharge capacitors before handling — use an insulated screwdriver across terminals or a dedicated capacitor discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before removing old capacitors. Verify MFD and voltage ratings on the data plate before installation.
Warranty: 1-year OEM factory warranty on both components. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier HB1CJX060000AAAA 5-ton split-system condenser. Always cross-reference the MFD and voltage ratings on your unit's data plate before ordering. If you're unsure of fitment, our HVAC parts specialists verify compatibility before you purchase — no guesswork, no returns.

Frequently Asked Questions

Does this Capacitor fit my Carrier HB1CJX060000AAAA?

Yes. This is the factory-specified OEM capacitor for the Carrier HB1CJX060000AAAA. 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 capacitor on my Carrier HB1CJX060000AAAA?

Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.

My AC hums but won’t start. What part do I need?

An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).

Is this capacitor 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 capacitor?

OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.

How fast does National HVAC Parts ship?
