What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WJA360000K000A1 — 70+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 WJA360000K000A1 — 70+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 round dual run capacitor (Part No. 1177750) stores and delivers the electrical charge that starts and runs both the compressor and the condenser fan motor in your ICP WJA360000K000A1 unit. Rated at 70+10 MFD and 370 volts, the larger 70 MFD side serves the compressor (HERM) while the 10 MFD side serves the fan motor (FAN). A weak or failed run capacitor is the single most common cause of a no-start outdoor unit. Symptoms include a compressor that hums but won't start, a condenser fan that's slow to spin or needs a push, hard starting, and a bulged or leaking capacitor top.

Compatibility

Direct OEM replacement for the ICP WJA360000K000A1 condensing unit. Also fits Tempstar, Heil, and Comfortmaker units calling for a 70+10 MFD 370V dual run capacitor. A 440V capacitor of the same MFD may be used as an upgrade; always match the microfarad rating exactly.

Installation Guide

Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter.
Access — Remove the condenser service panel.
Document — Photograph the HERM, FAN, and C wiring before touching anything.
Remove — Discharge the old capacitor across its terminals with an insulated resistor, then remove the leads and mounting strap.
Install — Secure the new capacitor and reconnect HERM, FAN, and C terminals per your photo.
Test — Restore power and verify the compressor and fan start promptly on a cooling call.

Signs You Need a Replacement

Compressor hums but won't start.
Condenser fan spins slowly or only after a manual push.
Bulged, swollen, or leaking capacitor top.
Out-of-tolerance MFD reading on a capacitor meter.

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?
