What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WCA3362GKN300 — 440V Dual Run | 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 WCA3362GKN300 — 440V Dual Run | 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 dual-run capacitor (part number 1174852) provides the starting torque and continuous running phase shift for both the compressor and the condenser fan motor on your ICP WCA3362GKN300 unit. Rated at 50+5 MFD and 440 volts, the larger 50 MFD terminal feeds the compressor while the 5 MFD terminal feeds the fan motor. A weak or failed capacitor is one of the most common causes of an air conditioner that won't cool. Typical failure symptoms include a hard-starting or buzzing compressor, a condenser fan that won't spin (or needs a push to start), a bulging or leaking capacitor top, and a unit that trips the breaker or clicks on and off.

Compatibility

This capacitor is the factory-specified replacement for the ICP (Tempstar / Heil / Comfortmaker) WCA3362GKN300 condensing unit and fits numerous ICP-family air conditioners using a 50+5 MFD, 440V round dual-run capacitor. Confirm your existing capacitor's microfarad ratings and voltage before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage and safely discharge the old capacitor with an insulated resistor.
Access — Remove the service panel to reach the electrical compartment.
Document — Photograph the HERM, FAN, and C (common) terminal wiring before disconnecting.
Remove — Disconnect the spade terminals and loosen the mounting strap holding the old capacitor.
Install — Secure the new capacitor in the strap and reconnect each wire to its matching HERM / FAN / C terminal per your photo.
Test — Restore power, call for cooling, and confirm the compressor and condenser fan start smoothly.

Signs You Need a Replacement

Condenser fan won't spin or needs a manual push to start.
Compressor hums, hard-starts, or won't run.
Bulging, swollen, or leaking capacitor top.
Unit short-cycles or trips the breaker.

Frequently Asked Questions

Does this Capacitor fit my ICP WCA3362GKN300 — 440V Dual Run | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WCA3362GKN300 — 440V Dual Run | 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 WCA3362GKN300 — 440V Dual Run | 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?
