What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WCH4604GKA110 — 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 WCH4604GKA110 — 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 genuine OEM round dual run capacitor (part number 1186266) is rated 80 + 7.5 MFD at 440V and serves the ICP / Tempstar / Heil WCH4604GKA110 heat pump. A dual run capacitor stores and delivers the electrical charge that both the compressor (80 MFD side) and the condenser fan motor (7.5 MFD side) need to start and run smoothly. As capacitors age they lose capacitance, bulge, or short out — leaving the compressor or fan unable to start. Classic symptoms include a humming compressor that won't start, a fan blade you have to spin by hand to get going, hard starting, and breaker trips.

Specifications

Spec	Value
Part Number	1186266
Type	Round Dual Run Capacitor
Brand	ICP (Tempstar / Heil)
Capacitance	80 + 7.5 MFD
Voltage	440V (440/370V compatible)

Compatibility

Designed for the ICP / Tempstar / Heil WCH4604GKA110 heat pump and compatible across Tempstar, Heil, and Comfortmaker condensing units that specify an 80+7.5 MFD 440V dual run capacitor. Match MFD values and voltage to the original before installing — a 440V capacitor can replace a 370V unit, but never the reverse.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condensing unit service panel.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Discharge the old capacitor across the terminals with an insulated resistor, then unclip the mounting strap and lift it out.
Install — Mount the new capacitor and connect leads to the matching HERM (compressor), FAN, and C (common) terminals per your photo.
Test — Restore power and confirm the compressor and fan start without hesitation.

Signs You Need a Replacement

Compressor hums but won't start
Condenser fan needs a manual spin to start
Capacitor top is bulging, leaking, or swollen
Hard starting, weak cooling, or breaker trips

Frequently Asked Questions

Does this Capacitor fit my ICP WCH4604GKA110 — 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WCH4604GKA110 — 440V | 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 WCH4604GKA110 — 440V | 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.
