What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WJH360000KTP0A2 — OEM 1177750 | 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 WJH360000KTP0A2 — OEM 1177750 | 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 is the genuine OEM dual run capacitor (part number 1177750) for the ICP / Tempstar / Heil WJH360000KTP0A2 condensing unit. It is a round 370V capacitor rated at 70+10 MFD — the 70 MFD section supports the compressor and the 10 MFD section supports the condenser fan motor. The capacitor provides the phase shift that both motors need to start and run efficiently. A weak or failed run capacitor is one of the most common causes of a no-cooling call: the compressor may hum and trip on overload, the condenser fan may fail to spin, or the unit may short-cycle and draw high amperage. Capacitors often fail with a bulged or leaking top, but can also drift out of tolerance while still appearing intact.

Compatibility

Direct-fit OEM replacement for the ICP / Tempstar / Heil model WJH360000KTP0A2 and related Comfortmaker-family condensing units that use the 1177750 70+10 MFD 370V dual run capacitor. Match the MFD ratings and voltage on your existing capacitor before ordering; a 440V capacitor of the same MFD is also an acceptable upgrade.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage and discharge the capacitor across its terminals with an insulated resistor before touching it.
Access — Remove the condenser control box cover to reach the capacitor.
Document — Photograph the HERM, FAN, and C terminal wiring before removing any leads.
Remove — Pull the spade connectors, loosen the mounting strap, and lift out the old capacitor.
Install — Secure the new capacitor in the strap and reconnect HERM to compressor, FAN to fan motor, and C to common per your photos.
Test — Restore power, confirm the compressor and condenser fan start promptly, and verify normal running amperage.

Signs You Need a Replacement

Compressor hums but will not start, then trips on overload.
Condenser fan does not spin or needs a push to start.
Capacitor top is bulged, domed, or leaking oil.
Unit short-cycles or draws abnormally high amperage.

Frequently Asked Questions

Does this Capacitor fit my ICP WJH360000KTP0A2 — OEM 1177750 | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WJH360000KTP0A2 — OEM 1177750 | 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 WJH360000KTP0A2 — OEM 1177750 | 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?
