What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WJA360000KTP0B1 — 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 WJA360000KTP0B1 — 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 1177750) provides the running torque for both the compressor and the condenser fan motor in the ICP / Heil / Tempstar / Comfortmaker WJA360000KTP0B1 air conditioner. It is a round 370V capacitor rated 70+10 MFD: the 70 MFD side serves the compressor (HERM terminal) and the 10 MFD side serves the condenser fan (FAN terminal), with a shared common (C) terminal. A weak or failed run capacitor is the single most common AC failure — it causes hard starting, a humming compressor that won't spin up, a fan that won't turn, breaker trips, and short cycling. Replacing it restores full starting and running performance.

Compatibility

Direct-fit replacement for the ICP family condensing unit WJA360000KTP0B1 and other WJA-series units specifying a 70+10 MFD, 370V dual run capacitor. Fits the equivalent rebadged Heil, Tempstar, and Comfortmaker models built on this platform.

Installation Guide

Safety First — Disconnect power and verify zero voltage, then discharge the capacitor across its terminals with an insulated resistor; capacitors hold a lethal charge.
Access — Remove the condenser control panel cover.
Document — Photograph the HERM, FAN, and C wiring before disconnecting.
Remove — Pull the leads, loosen the strap bracket, and lift out the old capacitor.
Install — Seat the new capacitor in the strap and reconnect HERM, FAN, and C exactly per your photo.
Test — Restore power and confirm the compressor and fan start promptly and run smoothly.

Signs You Need a Replacement

Compressor hums but won't start (hard start)
Condenser fan won't spin or needs a push to start
Bulging, leaking, or swollen capacitor top
Short cycling or tripped breaker on cooling calls

Frequently Asked Questions

Does this Capacitor fit my ICP WJA360000KTP0B1 — 370V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WJA360000KTP0B1 — 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 WJA360000KTP0B1 — 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?
