What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3482115LKB1 — 55+10 MFD 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 WPG3482115LKB1 — 55+10 MFD 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 OEM dual run capacitor (part #1176101) provides the starting and running phase shift for both the compressor and the condenser fan motor in your ICP WPG3482115LKB1 condensing unit. It is a round, 370-volt capacitor rated at 55+10 MFD — 55 microfarads for the compressor (HERM terminal) and 10 microfarads for the fan (FAN terminal), sharing a common (C) terminal. This listing includes both the round 2.5" mounting clamp (part #1064218) and the oval capacitor clamp (part #1171552) for secure installation. A weak or bulging capacitor is the single most common cause of an AC unit that hums but won't start, or that trips on overload.

Compatibility

This 55+10 MFD 370V dual run capacitor is the factory-specified capacitor for the ICP WPG3482115LKB1 and fits many Heil, Tempstar, and Comfortmaker condensing units calling for a 55+10/370V round capacitor. A 440V capacitor of the same MFD may be substituted, but never use a lower voltage rating.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then discharge and verify zero voltage across all capacitor terminals with a multimeter.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Discharge the old capacitor, mark the wires, disconnect them, and loosen the mounting clamp.
Install — Secure the new capacitor with the included clamp and connect each wire to the matching HERM, FAN, or C terminal per your photo.
Test — Restore power, call for cooling, and confirm the compressor and fan start instantly without humming.

Signs You Need a Replacement

Outdoor unit hums but the compressor or fan won't start.
Capacitor top is bulged, swollen, or leaking oil.
Condenser fan spins slowly or only starts when pushed by hand.
Measured capacitance is outside ±6% of the 55+10 MFD rating.

Frequently Asked Questions

Does this Capacitor fit my ICP WPG3482115LKB1 — 55+10 MFD 370V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPG3482115LKB1 — 55+10 MFD 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 WPG3482115LKB1 — 55+10 MFD 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.
