What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH10JA036000ACAA Package Heat Pump 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 PH10JA036000ACAA Package Heat Pump.

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 Run Capacitor for PH10JA036000ACAA Package Heat Pump

The run capacitor on your Carrier PH10JA036000ACAA package unit stores and releases a phase-shifted electrical charge that keeps the compressor and condenser fan motor spinning under load. As it degrades, the warning signs are clear: a steady hum from the outdoor unit with a fan that won't start (or only starts when nudged), hard starting, warm air at the vents, frequent short-cycling, or a breaker that trips when the system calls for cooling. A swollen, domed, or leaking top confirms the diagnosis. This is a dual-run capacitor feeding both the compressor (HERM) and fan (FAN) terminals, typically 35/5 MFD at 440V for this 3-ton class unit and held to a precise OEM tolerance of ±5%. Carrier specifies these exact MFD and voltage values to match the compressor and motor windings in this model. Why OEM matters here: generic capacitors are frequently built to ±10–15% tolerance with cheaper dielectric film. Even a few MFD of drift forces the compressor to pull excess current, overheating its windings and slashing its service life — turning a cheap fix into a costly compressor replacement. Installation difficulty: 2 of 5. Tools needed: 1/4" and 5/16" nut drivers, an insulated screwdriver, and a multimeter with a capacitance setting to confirm the failed reading. SAFETY: a run capacitor holds a charge that can shock you even after power is cut — always discharge it across the terminals with an insulated screwdriver before disconnecting the wires. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PH10JA036000ACAA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH10JA036000ACAA Package Heat Pump?

Yes. This is the factory-specified OEM capacitor for the Carrier PH10JA036000ACAA Package Heat Pump. 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 PH10JA036000ACAA Package Heat Pump?

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.
