What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3304040RKC1 — 370V | 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 WPG3304040RKC1 — 370V | 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 is the genuine OEM round run capacitor (part number 1095021) for the ICP / Tempstar / Heil WPG3304040RKC1 packaged unit. Rated at 2.0 MFD and 370 volts, this single-run capacitor provides the steady phase shift that keeps a small fan or auxiliary motor running smoothly after start-up. It ships with the factory mounting clamp so it drops straight into the original bracket location. When a run capacitor weakens, the motor it serves draws excess amperage, runs hot, hums, or fails to come up to full speed — and a fully failed capacitor will stop the motor entirely. Replacing a bulging, leaking, or out-of-tolerance capacitor restores correct operation and protects the motor windings from premature burnout.

Compatibility

Engineered for the ICP WPG3304040RKC1 and shared across many Tempstar, Heil, Comfortmaker, and Day & Night packaged gas/electric units that use a 2.0 MFD 370V auxiliary run capacitor. Always confirm the MFD and voltage rating stamped on your original capacitor before installing.

Installation Guide

Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter. A charged capacitor can hold a dangerous voltage; discharge it across a 20k-ohm resistor before handling.
Access — Remove the electrical/service panel to expose the capacitor.
Document — Photograph every wire and terminal before disconnecting.
Remove — Loosen the mounting clamp, pull the spade terminals, and lift out the old round capacitor.
Install — Secure the new capacitor in the clamp and reconnect the leads exactly per your photo.
Test — Restore power and verify the motor reaches full speed and draws correct amperage.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my ICP WPG3304040RKC1 — 370V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPG3304040RKC1 — 370V | 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 WPG3304040RKC1 — 370V | 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?

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.
