What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PF4MNA036T00AAAA 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 PF4MNA036T00AAAA.

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 Single Run Capacitor 15 MFD 370V for Model PF4MNA036T00AAAA

This is the factory-specified OEM single run capacitor for the Carrier PF4MNA036T00AAAA fan coil air handler. The run capacitor maintains the continuous phase shift required to keep the blower or condenser fan motor running efficiently after startup. When this component degrades or fails, you'll typically notice symptoms such as a humming motor that won't spin, intermittent shutdowns during operation, or the system drawing excess amperage — all of which can lead to motor burnout if left unaddressed. Replacing the capacitor promptly with the correct OEM-spec part is the most cost-effective repair available for this failure mode.

Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals
OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to factory ±5% MFD tolerance. Generic capacitors often ship at ±10% tolerance, causing the motor to run outside its design envelope — shortening motor life and potentially voiding equipment warranties. Note: Carrier sources capacitors from approved third-party manufacturers; the capacitor label will reflect the capacitor maker's name, not Carrier.
Install difficulty: 1/5 — One of the simplest HVAC repairs possible. Tools needed: screwdriver, needle-nose pliers, and a multimeter to verify discharge. Always discharge the old capacitor fully before disconnecting any terminals — capacitors can hold a lethal charge even after power is removed. Photograph all wiring before removal.
Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Directly fits Carrier model PF4MNA036T00AAAA fan coil units. Always verify the MFD and voltage rating on your unit's data plate before ordering — using the wrong capacitor rating will damage the motor. Our fitment team is available to confirm compatibility before you purchase. Order today and get back up and running fast — this part ships same day.

Frequently Asked Questions

Does this Capacitor fit my Carrier PF4MNA036T00AAAA?

Yes. This is the factory-specified OEM capacitor for the Carrier PF4MNA036T00AAAA. 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 PF4MNA036T00AAAA?

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.
