What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3424090RKC1 — 370/440V | 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 WPG3424090RKC1 — 370/440V | 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 round run capacitor (with mounting clamp) provides the steady phase shift that keeps a fan or auxiliary motor running efficiently in the ICP Tempstar Heil WPG3424090RKC1. Rated at 2.0 MFD and 370/440V, it stores and releases the charge that maintains motor torque during operation. A weak or failed capacitor is one of the most common HVAC service calls — symptoms include a motor that hums but will not start, a fan that spins slowly or stalls, overheating, or a capacitor with a bulged or leaking top. This is an exact OEM replacement for part 1095021 and includes the round clamp for secure mounting.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter. Discharge the old capacitor across its terminals with an insulated screwdriver before touching it.
Access — Remove the electrical/control panel cover.
Document — Photograph the terminal wiring before disconnecting.
Remove — Pull the leads, loosen the clamp, and remove the old capacitor.
Install — Secure the new capacitor with the clamp and reconnect leads per your photo.
Test — Restore power and confirm the motor starts and runs smoothly.

Signs You Need a Replacement

Motor hums but fails to start.
Fan runs slowly, intermittently, or stalls.
Bulged, leaking, or burst capacitor top.

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.
