What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH13NR048000AHAA 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 PH13NR048000AHAA.

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 88-108 MFD 330V for Model PH13NR048000AHAA

This is the OEM factory-specified start capacitor for the Carrier PH13NR048000AHAA heat pump condenser. The start capacitor delivers the short but powerful surge of electrical energy needed to kick the compressor motor into motion on every cooling or heating cycle. Without a healthy start capacitor, the compressor struggles to turn over — you'll typically hear a loud hum or clicking sound followed by a tripped breaker, a hard-start delay, or a complete no-start condition. Replacing a failed start capacitor promptly protects the compressor from heat and winding damage caused by prolonged locked-rotor current draw.

Specs: 88–108 MFD (microfarad) | 330V rated | Round case | 2.06" diameter × 4.37" length | Includes bleed resistor | 50/60 Hz
OEM vs Generic: OEM Carrier capacitors (P281-8806) are manufactured to exact factory MFD tolerance, ensuring reliable cold starts and full compressor protection. Generic start capacitors often carry wider tolerance bands that can under-boost the compressor motor, shortening its service life.
Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit. Swap terminals one at a time to avoid miswiring.
Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM drop-in for the Carrier PH13NR048000AHAA 4-ton heat pump condenser. Always verify the MFD range and voltage rating on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH13NR048000AHAA?

Yes. This is the factory-specified OEM capacitor for the Carrier PH13NR048000AHAA. 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 PH13NR048000AHAA?

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?
