What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WJH360000K000A2 — 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 WJH360000K000A2 — 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 1177750) provides the starting torque and steady-state phase shift for both the compressor and the condenser fan motor on your ICP heat pump. Rated 70+10 MFD at 370V, the 70 MFD section serves the compressor (HERM) and the 10 MFD section serves the fan (FAN), with a shared common (C) terminal. A weak or failed capacitor is one of the most common causes of a no-cool / no-heat call: the compressor may hum but not start, the outdoor fan may stall, or the unit may trip on overload. Capacitors degrade with heat and age, so a bulging top or out-of-tolerance microfarad reading means replacement.

Specifications

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

Compatibility

Direct OEM fit for ICP / Tempstar / Heil heat pump model WJH360000K000A2. A 370V capacitor is interchangeable in 440V applications of the same MFD, but never substitute a lower voltage rating. Confirm the 70+10 MFD value on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power, then verify zero voltage and discharge the capacitor across its terminals with an insulated resistor before touching.
Access — Remove the outdoor unit's electrical access service panel.
Document — Photograph the HERM, FAN, and C wire connections before disconnecting.
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 each lead to HERM, FAN, and C exactly per your photo.
Test — Restore power and confirm the compressor and condenser fan start and run smoothly.

Signs You Need a Replacement

Compressor hums or buzzes but won't start
Outdoor fan won't spin or needs a push to start
Bulging, leaking, or domed capacitor top
Measured capacitance outside the ±6% tolerance of 70+10 MFD

Frequently Asked Questions

Does this Capacitor fit my ICP WJH360000K000A2 — 70+10 MFD 370V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WJH360000K000A2 — 70+10 MFD 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 WJH360000K000A2 — 70+10 MFD 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?

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.
