What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WJH348000KTP0A2 — 370V 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 WJH348000KTP0A2 — 370V 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 a 70+10 MFD, 370-volt round capacitor designed for the ICP WJH348000KTP0A2 heat pump system. A dual run capacitor provides the steady phase shift that keeps both the compressor (70 MFD side) and the condenser fan motor (10 MFD side) running efficiently after startup. When a run capacitor weakens or fails, the system loses torque and draws excess amperage. Common failure symptoms include a humming compressor that will not start, a condenser fan that spins slowly or only when pushed by hand, hard starting on hot days, and tripped breakers. Capacitors are a wear item that degrade with heat and age, so replacing a bulging or out-of-tolerance unit restores rated capacity and protects the more expensive motor and compressor.

Specifications

Spec	Value
OEM Part Number	1177750
Type	Dual Run Capacitor (Round)
Brand	ICP / Heil / Tempstar
Capacitance	70 + 10 MFD
Voltage Rating	370 VAC
Tolerance	±6%

Compatibility

Engineered as the factory replacement for the ICP / Heil / Tempstar / Comfortmaker WJH348000KTP0A2 packaged heat pump. The 70+10 MFD 370V rating also serves as a direct match for many condensing units that call for this exact dual value — always confirm your existing capacitor's printed MFD and voltage before ordering.

Installation Guide

Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter. Discharge the old capacitor across its terminals with an insulated screwdriver before touching.
Access — Remove the service panel on the condensing unit to expose the capacitor mounting bracket.
Document — Photograph all wires and terminal positions (HERM, FAN, C) before disconnecting anything.
Remove — Pull the spade connectors off the old capacitor and loosen the retaining strap.
Install — Mount the new capacitor in the strap and reconnect each wire to the matching HERM, FAN, and COMMON terminal per your photo.
Test — Restore power and confirm the compressor and condenser fan start promptly and run smooth.

Signs You Need a Replacement

Compressor hums but will not start, or trips the breaker
Condenser fan spins slowly or only after a manual push
Visibly bulging, leaking, or domed capacitor top
Measured capacitance reads outside the ±6% tolerance

Frequently Asked Questions

Does this Capacitor fit my ICP WJH348000KTP0A2 — 370V Round | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WJH348000KTP0A2 — 370V 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 WJH348000KTP0A2 — 370V 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.
