OEM Carrier Dual Run & Start Capacitor Kit for Model PH10JA018000AAAA

This factory-matched OEM capacitor kit contains both the P291-2553RS Dual Run Capacitor and the P281-1356 Start Capacitor — the two capacitors specified for the Carrier PH10JA018000AAAA heat pump. The dual run capacitor keeps the compressor and condenser fan motor running continuously, while the start capacitor delivers the high-torque burst of energy needed to get the compressor spinning on every cycle. When either capacitor weakens or fails, you may experience hard-start faults, compressor humming with no motor movement, or the unit tripping on thermal overload shortly after startup. Replacing both as a kit ensures the entire capacitor circuit is restored to OEM specification in a single service call.

  • Dual Run Capacitor Specs (P291-2553RS / superseded by P291-2554RS): 25+5 MFD (µF) | 370V AC | Round case | Rated for condenser outdoor motor circuits | Factory ±3% tolerance
  • Start Capacitor Specs (P281-1356): 135–155 MFD (µF) | 330V AC | Round case | 2.56″ diameter × 4.37″ height | Includes bleed resistor for safe discharge
  • OEM vs Generic: OEM capacitors are built to Carrier's exact factory tolerance and tested to meet their reliability standards. Generic aftermarket capacitors often carry ±10% MFD variance, which accelerates compressor wear, increases hard-start events, and can shorten overall system lifespan — particularly critical in heat pump applications that run year-round.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated resistor or dedicated discharge tool). Tools needed: 1/4″ nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Replace one capacitor at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty on both components. Ships same business day from our warehouse.

Compatibility: This kit is specified for the Carrier PH10JA018000AAAA heat pump. Always verify MFD and voltage ratings on your unit's data plate before installation. Not sure it fits? Our HVAC parts team confirms fitment before you order — reach out before checkout.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH10JA018000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH10JA018000AAAA. 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 PH10JA018000AAAA?
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.
