OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH13NR036000ACAA

This factory-matched capacitor kit contains both the P291-5073RS Dual Run Capacitor and the P281-8806 Start Capacitor — the two OEM-specified capacitors for the Carrier PH13NR036000ACAA heat pump condenser. The dual run capacitor continuously powers both the compressor and condenser fan motor during operation, while the start capacitor delivers the high-torque kick needed to start the compressor under load. When either fails, symptoms include a humming unit that won't start, a compressor that trips on thermal overload, short-cycling, or a system that trips the breaker immediately after startup.

  • Dual Run Capacitor (P291-5073RS) Specs: 50+7.5 MFD (microfarad) | 370V rated | Round case | Factory-matched ±3% tolerance — powers both the compressor and condenser fan motor simultaneously
  • Start Capacitor (P281-8806) Specs: 88–108 MFD | 330V rated | Round case with integrated bleed resistor — provides compressor start-boost and safely self-discharges between cycles
  • OEM vs Generic: OEM capacitors meet Carrier's exact factory tolerances. Aftermarket units commonly run ±10% MFD deviation, placing excess stress on the compressor windings and shortening equipment life — especially critical in a heat pump that runs year-round.
  • Install Difficulty: 2/5 — Always discharge capacitors before handling (both can retain a lethal charge). Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting. The start capacitor includes a bleed resistor — do not bypass it.
  • Warranty: 1-year OEM factory warranty on both components. Ships same business day from our warehouse in original Carrier/Totaline packaging.

Compatibility: This kit is factory-specified for the Carrier PH13NR036000ACAA 3-ton heat pump condenser. Always verify the MFD and voltage ratings on your unit's data plate before installation.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH13NR036000ACAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH13NR036000ACAA. 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 PH13NR036000ACAA?
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.
