OEM Carrier Single Run Capacitor 10 MFD 370V for Model PH1REA036000AAWA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PH1REA036000AAWA heat pump system. The run capacitor provides a continuous phase-shifted electrical charge that keeps the blower or condenser fan motor spinning at full torque after startup. When it degrades or fails, symptoms include a motor that hums but won't spin, sluggish motor startup, intermittent short-cycling, or a system that trips on high-pressure lockout due to reduced airflow from a lagging fan.

  • Specs: 10 MFD (microfarad) | 370V rated | Oval case | ±5% capacitance tolerance | 50/60 Hz | Non-PCB, RoHS compliant
  • OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor matched to factory tolerances. Generic capacitors often carry a wider ±10% tolerance, which causes motors to draw excess amperage, shortening both motor and compressor life.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling by shorting terminals through a 20kΩ resistor or insulated screwdriver. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph wiring before disconnecting. Confirm MFD and voltage ratings match your unit's data plate.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for Carrier model PH1REA036000AAWA. Note: P291-1003 has been superseded by P291-1004 (440V-rated upgrade); both are electrically compatible as the higher voltage rating is an improvement, not a restriction. Always verify MFD rating on your unit's data plate before ordering. Have a fitment question?

Frequently Asked Questions

Does this Capacitor fit my Carrier PH1REA036000AAWA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH1REA036000AAWA. 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 PH1REA036000AAWA?
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.
