My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Overview

This OEM dual run capacitor (part number 1171552) is the factory oval capacitor for the ICP RHS036L0BA0AAAA system. Rated at 45+5 MFD and 440V, it provides the phase shift that starts and runs both the compressor and condenser fan motor. A failed capacitor is one of the most common HVAC service calls — symptoms include a humming compressor that won't start, a fan that needs a push to spin, hard starting, and tripped breakers. Capacitors weaken with heat and age, so replacing a bulging or out-of-spec unit restores reliable starting.

Installation Guide

Safety First — Disconnect power, then discharge the old capacitor across its terminals with an insulated screwdriver and verify zero voltage with a multimeter.
Access — Remove the service panel on the condensing unit.
Document — Photo all wires (HERM, FAN, C terminals) before disconnecting.
Remove — Release the mounting strap and pull the old capacitor.
Install — Secure the new capacitor and reconnect each lead to the matching terminal per your photo.
Test — Restore power and verify the compressor and fan start cleanly.

Frequently Asked Questions

Does this Capacitor fit my ICP RHS036L0BA0AAAA — 45+5 MFD 440V Oval | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP RHS036L0BA0AAAA — 45+5 MFD 440V Oval | Ships Today. 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 ICP RHS036L0BA0AAAA — 45+5 MFD 440V Oval | Ships Today?

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 ICP 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 ICP 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?
