OEM Carrier Single Run Capacitor P291-1503 for Model PF1MNC036008AAAA

This is the genuine OEM single run capacitor for the Carrier PF1MNC036008AAAA air handler/fan coil unit, sold under OEM part number P291-1503. A single run capacitor maintains the steady electrical charge required to keep either the compressor or the condenser fan motor spinning during normal operation. Unlike a dual run capacitor, a single run unit is dedicated to one motor — making an exact MFD and voltage match absolutely critical for reliable, long-term performance. Common failure symptoms include the motor humming but failing to start, the system tripping on high-pressure lockout, or a burning smell coming from the unit.

  • OEM Part Number: P291-1503 | Single Run Capacitor | Factory-specified replacement for Carrier model PF1MNC036008AAAA | ±5% MFD tolerance or tighter as factory-rated
  • OEM vs. Generic: This is a genuine Carrier OEM capacitor — factory-tested to exact tolerances. Aftermarket alternatives frequently deviate ±10–15% MFD, increasing motor start stress, accelerating winding wear, and voiding equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling (use a 20,000 Ω resistor or insulated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, insulated multimeter. Photograph all wiring connections before disconnecting the old unit.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our fulfillment warehouse.

Compatibility: Engineered specifically for the Carrier PF1MNC036008AAAA fan coil unit. Before ordering, confirm the MFD rating and voltage stamped on your existing capacitor's label or your unit's data plate — single run capacitors must match these values exactly.

Frequently Asked Questions

Does this Capacitor fit my Carrier PF1MNC036008AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PF1MNC036008AAAA. 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 PF1MNC036008AAAA?
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.
