What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3482115RKB1 — 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 WPG3482115RKB1 — 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) is the round 370V, 55+10 MFD capacitor that supports both the compressor and condenser fan motor in your ICP, Tempstar, or Heil WPG3482115RKB1 condensing unit. A run capacitor stores and discharges electrical energy to keep both motors running efficiently. When it weakens or fails, you'll notice the compressor or fan struggling to start, humming, short-cycling, or tripping the breaker. This listing ships with the OEM round capacitor plus both mounting clamps (#1171552 oval clamp and #1064218 2.5" round clamp) so installation is complete out of the box.

Compatibility

Engineered as a direct OEM fit for the ICP/Tempstar/Heil WPG3482115RKB1 package unit and other systems using a 55+10 MFD 370V round dual run capacitor. Always verify the MFD and voltage rating printed on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter. Capacitors hold a charge — discharge across the terminals with an insulated resistor before touching.
Access — Remove the service panel on the control side of the condensing unit.
Document — Photograph all wires (HERM, FAN, COMMON) before disconnecting.
Remove — Loosen the mounting clamp, pull each spade connector, and remove the old capacitor.
Install — Secure the new capacitor with the included clamp and reconnect wires to the matching HERM/FAN/C terminals per your photo.
Test — Restore power and confirm the compressor and condenser fan start and run smoothly.

Signs You Need a Replacement

Compressor or fan hums but won't start

Frequently Asked Questions

Does this Capacitor fit my ICP WPG3482115RKB1 — 55+10 MFD 370V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPG3482115RKB1 — 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 WPG3482115RKB1 — 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?
