What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY1PPB036060AAAA 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 PY1PPB036060AAAA.

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 4 MFD 370V for Model PY1PPB036060AAAA

This is the factory-authorized OEM single run capacitor for the Carrier PY1PPB036060AAAA. The run capacitor stores and releases the electrical charge required to keep the condenser fan motor running continuously throughout every cooling cycle. A failing run capacitor typically presents as a humming condenser with no fan movement, a fan that spins only when manually assisted, or intermittent short-cycling — all of which will quickly escalate to compressor damage if left unaddressed.

Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case form factor | 50/60 Hz | Replaces OEM part numbers P291-0403 and P291-1503 (superseded)
OEM vs Generic: This is a genuine Carrier factory-authorized replacement, manufactured to exact ±5% MFD tolerance. Generic capacitors commonly run ±10% or worse, accelerating motor bearing wear and reducing compressor longevity over multiple seasons.
Install difficulty: 2/5 — Always disconnect power at the disconnect box and allow 5 minutes for the capacitor to self-discharge before touching any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance setting). Photograph all wire connections before removal.
Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM fit for Carrier model PY1PPB036060AAAA. Always verify the MFD and voltage rating on your unit's data plate before ordering — if your plate shows 370V you may substitute a 440V-rated capacitor, but MFD must match exactly. Have a question about fitment? Our HVAC parts team verifies compatibility before you order — reach out before you buy.

How do I replace the capacitor on my Carrier PY1PPB036060AAAA?

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.
