What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG4364060RKB1 — 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 WPG4364060RKB1 — 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 (part #1064218) is a 2.5 MFD motor-run capacitor engineered for the ICP / Tempstar / Heil WPG4364060RKB1 packaged gas-electric unit. A run capacitor stores and releases electrical energy to keep the condenser fan or auxiliary motor running smoothly and efficiently after start-up. When a capacitor weakens or fails, the motor it serves struggles to start, runs hot, hums without spinning, or cycles on its internal overload. Replacing a failed capacitor restores proper amp draw, protects the motor windings, and prevents nuisance high-head pressure trips. This is a direct OEM-spec replacement that matches the original microfarad rating, voltage tolerance, and round housing for a clean drop-in fit.

Compatibility

Designed specifically for the ICP / Tempstar / Heil / Comfortmaker WPG4364060RKB1 packaged gas-electric unit. Always confirm the MFD rating stamped on your existing capacitor matches 2.5 MFD before installing.

Installation Guide

Safety First — Disconnect power at the unit disconnect and breaker, then verify zero voltage with a multimeter. Discharge the old capacitor across its terminals with an insulated resistor before touching it.
Access — Remove the electrical service panel to expose the capacitor mounting bracket.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note terminal markings, pull the spade connectors, and loosen the mounting strap to free the old round capacitor.
Install — Secure the new capacitor in the strap and reconnect each wire to the matching terminal per your photo.
Test — Restore power and confirm the motor starts promptly and runs at normal amp draw.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my ICP WPG4364060RKB1 — Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPG4364060RKB1 — 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 WPG4364060RKB1 — 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?
