What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WJA360000KTP0A1 — 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 WJA360000KTP0A1 — 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 dual run capacitor (part #1177750) is the genuine replacement for ICP/Tempstar/Heil model WJA360000KTP0A1. A dual run capacitor delivers the constant phase shift the compressor and condenser fan motor need to start and run efficiently. The 70 MFD section feeds the compressor (HERM terminal) while the 10 MFD section drives the condenser fan motor (FAN terminal), both rated at 370 volts. As a capacitor weakens, both motors draw excess current and overheat — the leading cause of summer no-cooling failures. Common symptoms include a humming compressor that won't start, a fan that needs a manual spin, a bulged or leaking can, and breakers tripping under load.

Specifications

Spec	Value
Part Number	1177750
Type	Dual Run, Round
Brand	ICP (Tempstar / Heil)
Capacitance	70 + 10 MFD
Voltage	370V
Terminals	HERM / FAN / C

Compatibility

Directly fits ICP, Tempstar, Heil, Comfortmaker, and Arcoaire condensing units using OEM part 1177750, including model WJA360000KTP0A1. Confirm the MFD rating and voltage on your existing capacitor before ordering — a 370V capacitor can replace a 440V unit of the same MFD, but never the reverse.

Installation Guide

Safety First — Disconnect power at the condenser disconnect and breaker, then verify zero voltage with a multimeter. Discharge the capacitor across its terminals with an insulated screwdriver before handling.
Access — Remove the condenser service panel.
Document — Photograph all wire positions (HERM, FAN, C) before disconnecting.
Remove — Pull the spade connectors, loosen the mounting strap, and remove the old capacitor.
Install — Secure the new capacitor in the strap and reconnect each wire to its matching terminal per your photo.
Test — Restore power and confirm the compressor and condenser fan start immediately and run smoothly.

Signs You Need a Replacement

Compressor hums but won't start, or trips the breaker
Condenser fan won't spin until pushed by hand
Bulged, swollen, or leaking capacitor can
Measured MFD reads outside ±6% of the rated 70+10 value

Frequently Asked Questions

Does this Capacitor fit my ICP WJA360000KTP0A1 — Round | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WJA360000KTP0A1 — 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 WJA360000KTP0A1 — 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.
