What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3482090RKB1 — Round | 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 WPG3482090RKB1 — Round | 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 1176101) is rated 55+10 MFD at 370V and serves both the compressor (55 MFD) and the condenser fan motor (10 MFD) on the ICP / Tempstar / Heil WPG3482090RKB1 packaged unit. This listing includes the OEM oval (1171552) and round 2.5" (1064218) mounting clamps. The run capacitor provides the phase shift that keeps the compressor and fan motor running efficiently. A weak or failed capacitor is the single most common cause of an outdoor unit that hums but won't start, a fan that spins slowly or not at all, or a compressor that trips on overload. Always replace a capacitor with one matching the original MFD and voltage rating.

Compatibility

Direct-fit OEM replacement for the ICP/Tempstar/Heil WPG3482090RKB1 packaged gas/electric unit and other ICP-family units calling for a 55+10 MFD 370V round dual run capacitor. Confirm the MFD values stamped on your old capacitor (HERM 55 / FAN 10) before installing.

Installation Guide

Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter. Discharge the capacitor across its terminals through an insulated resistor before touching it.
Access — Remove the electrical/control panel cover.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Note each lead's terminal, disconnect, loosen the mounting clamp, and remove the old capacitor.
Install — Secure the new capacitor with the included clamp and reconnect HERM (compressor), FAN, and C (common) leads exactly per your photo.
Test — Restore power, confirm the compressor and condenser fan start promptly, and verify steady amp draw.

Signs You Need a Replacement

Outdoor unit hums but compressor or fan won't start
Condenser fan spins slowly or needs a push to start
Capacitor top is bulged, leaking, or domed
Measured capacitance is well below the rated 55 or 10 MFD

Frequently Asked Questions

Does this Capacitor fit my ICP WPG3482090RKB1 — Round | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPG3482090RKB1 — Round | 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 WPG3482090RKB1 — Round | 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.
