What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WCH3362GKR4 — 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 WCH3362GKR4 — 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 dual run capacitor (part number 1174852) is the genuine replacement for the ICP / Tempstar / Heil WCH3362GKR4 heat pump. Rated at 50+5 MFD and 440 volts in a round (RD) can, it provides the phase-shifted starting and running torque for both the compressor (50 MFD side) and the condenser fan motor (5 MFD side) from a single component. A failing run capacitor is one of the most common causes of a no-cool or no-heat call: when the dielectric breaks down, the compressor and fan lose their running torque, draw excessive amperage, overheat, and trip on the internal overload. Replacing a weak capacitor restores correct amp draw, lowers operating temperature, and extends the life of the motors it feeds.

Compatibility

Engineered for the ICP-built WCH3362GKR4 heat pump and its Tempstar, Heil, Comfortmaker, and Arcoaire equivalents. As a 50+5 MFD / 440V round dual-run capacitor it also serves as a direct replacement in many comparable 3-ton ICP family condensers that specify the same rating. Always confirm the MFD and voltage stamped on the can of the capacitor you are removing.

Installation Guide

Safety First — Disconnect power at the condenser disconnect and verify zero voltage with a multimeter before touching any terminal. Discharge the old capacitor across HERM/FAN to C with an insulated resistor.
Access — Remove the condenser service panel to expose the electrical compartment.
Document — Photograph the wiring at the HERM, FAN, and C terminals before disconnecting.
Remove — Pull the spade connectors, loosen the mounting strap, and lift out the old round capacitor.
Install — Secure the new capacitor in the strap and reconnect each lead to the matching terminal per your photo.
Test — Restore power, confirm the compressor and fan start without hesitation, and verify amp draw is within nameplate spec.

Signs You Need a Replacement

Compressor or fan hums but will not start, or needs a stick-spin to get going.
Bulged, leaking, or swollen capacitor can.
Measured capacitance reads outside the rated ±6% (below ~47 or 4.7 MFD).
High compressor amp draw, repeated overload trips, or intermittent cooling.

Frequently Asked Questions

Does this Capacitor fit my ICP WCH3362GKR4 — Round | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WCH3362GKR4 — 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 WCH3362GKR4 — 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?

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.
