What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH15NB01800GBAAA 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 PH15NB01800GBAAA.

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 Start Capacitor 175–216 MFD 330V for Model PH15NB01800GBAAA

This is the genuine OEM start capacitor (part number P281-1766) factory-specified for the Carrier PH15NB01800GBAAA heat pump. The start capacitor delivers a high-energy electrical pulse to the compressor motor at the moment of startup, overcoming inertia and bringing the compressor up to operating speed within milliseconds. When this capacitor fails or weakens, the compressor may struggle to start, draw excessive amperage, trip the breaker, or fail to run entirely — often presenting as a system that hums but produces no cooling or heating output.

Specs: 175–216 MFD (microfarad) | 330V rated | Round case | ±5% factory tolerance | OEM part number P281-1766
OEM vs Generic: This is a genuine Carrier OEM part engineered to exact factory MFD and voltage specifications. Generic start capacitors often deviate in MFD tolerance, leading to hard starts, premature compressor wear, and shortened system life. Note: Carrier sources capacitors from select manufacturers — the label on the capacitor body may reflect the capacitor manufacturer's name, not Carrier's.
Install difficulty: 2/5 — Discharge the capacitor fully before handling any terminals (use a 20,000-ohm resistor or insulated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Always photograph wiring connections before removal to ensure correct reinstallation.
Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back up fast.

Compatibility: Engineered for the Carrier PH15NB01800GBAAA heat pump. Always verify the MFD range and voltage rating on your existing capacitor's label or unit data plate before ordering to confirm fitment. Need help? Our HVAC parts specialists verify compatibility before your order ships.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH15NB01800GBAAA?

Yes. This is the factory-specified OEM capacitor for the Carrier PH15NB01800GBAAA. 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 PH15NB01800GBAAA?

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?

Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
