OEM Carrier Run Capacitor P291-3554 for HA1BJX018000AEAA

This genuine Carrier dual run capacitor (P291-3554) supplies the steady phase shift your compressor and outdoor fan motor need to start smoothly and run efficiently. Built to the exact 35/5 MFD microfarad and voltage rating for the Carrier HA1BJX018000AEAA 1.5-ton condenser, it ensures both motors draw proper amperage and stay running under load. A weak or failed capacitor is the most common cause of a condenser that won't start, trips the breaker, or runs hot and short-cycles—usually the first part to test on a no-cool call. Installation is simple for a qualified technician: safely discharge the old capacitor, note the HERM, FAN, and C terminal wiring, install the replacement, and secure the mounting strap. Most jobs take about 20 minutes. Choosing the OEM capacitor guarantees correct dual ratings and tolerance, extending motor life and protecting your system. We keep this capacitor in stock and ship same-day on orders placed before 3PM CST. Order today from National HVAC Parts.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier HA1BJX018000AEAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier HA1BJX018000AEAA. 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 run capacitor on my Carrier HA1BJX018000AEAA?
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 run 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 run 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.
