What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPA3302000RKB1 — Oval + 2.0 MFD Round | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your ICP equipment which lists the model number WPA3302000RKB1 — Oval + 2.0 MFD Round | Ships Today.

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 run capacitor set keeps the condenser fan and motor circuits of your ICP/Tempstar/Heil WPA3302000RKB1 heat pump running at the correct phase and torque. It includes the oval clamp capacitor (OEM 1171552) and the 2.0 MFD round run capacitor (OEM 1095021), both rated at 440V. A run capacitor provides the constant phase shift a permanent-split-capacitor motor needs to spin smoothly; when it weakens or fails, the motor draws excess current, overheats, or fails to start. Common failure symptoms include a humming condenser fan that won't turn, the unit tripping the breaker, hard starting, or a bulged/leaking capacitor can. Replacing a tired capacitor is one of the most common and cost-effective HVAC repairs.

Compatibility

Designed as direct-fit OEM replacements for the ICP, Tempstar, Heil, Comfortmaker, and Arcoaire WPA3302000RKB1 heat pump, and shared across many ICP-family condensing units that use the same capacitor footprint. Always confirm the MFD and voltage stamped on your existing capacitor before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter at the contactor terminals.
Access — Remove the service panel on the condenser to expose the capacitor.
Document — Photograph all wire connections and terminal markings (HERM, FAN, C) before disconnecting anything.
Remove — Discharge the old capacitor across its terminals with an insulated screwdriver, then loosen the mounting clamp and pull the leads.
Install — Mount the new capacitor in the clamp and reconnect each lead to its matching terminal per your photo.
Test — Restore power and verify the fan and compressor start and run smoothly with normal amp draw.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my ICP WPA3302000RKB1 — Oval + 2.0 MFD Round | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPA3302000RKB1 — Oval + 2.0 MFD Round | 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 WPA3302000RKB1 — Oval + 2.0 MFD Round | 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?
