What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WTA3602000RKA1 — 80+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 WTA3602000RKA1 — 80+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 number 1173703) is rated 80+10 MFD at 370 volts and is the factory-specified motor-start/run component for the ICP WTA3602000RKA1 condensing unit. A dual-run capacitor delivers a phase-shifted current to both the compressor (the 80 MFD side) and the condenser fan motor (the 10 MFD side), allowing both motors to start under load and run efficiently. When the capacitor weakens or fails, the compressor and fan lose the torque needed to start. Common failure symptoms include a humming compressor that will not start, a condenser fan that spins slowly or only after a manual push, repeated tripped breakers, hard starting on hot days, and a bulged or leaking capacitor can. Replacing a marginal capacitor is one of the most common and inexpensive HVAC repairs.

Specifications

Compatibility

Engineered for the ICP / Tempstar / Heil WTA3602000RKA1 air conditioning condenser. The 80+10 MFD 370V rating must match your unit's original capacitor — always confirm the MFD and voltage stamped on the old can before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter. A charged capacitor can shock you — discharge it across the terminals with an insulated resistor.
Access — Remove the condenser service panel.
Document — Photograph all wire connections (HERM, FAN, C) before disconnecting.
Remove — Pull the spade connectors, loosen the mounting strap, and lift out the old capacitor.
Install — Mount the new capacitor, secure the strap, and reconnect each wire to the matching terminal per your photo.
Test — Restore power and verify the compressor and condenser fan start promptly and run smoothly.

Signs You Need a Replacement

How do I replace the capacitor on my ICP WTA3602000RKA1 — 80+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.
