What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPH3602000RKA1 | 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 WPH3602000RKA1 | 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 capacitor set powers the compressor and condenser fan on the ICP/Tempstar/Heil WPH3602000RKA1 heat pump. The primary component is a round dual run capacitor rated 80+10 MFD at 370V (part 1173703) — the 80 MFD side feeds the compressor and the 10 MFD side runs the condenser fan motor. The set also includes a 25 MFD 370V oval run capacitor (1176196) and the round capacitor mounting clamp (1064218). A capacitor stores and releases the phase-shifted charge that gets these motors spinning and keeps them running efficiently. A weak or bulged capacitor is the single most common cause of a heat pump that hums but won't start.

Compatibility

Fits the ICP/Tempstar/Heil/Comfortmaker WPH3602000RKA1 heat pump. The 80+10 MFD 370V dual run format is widely used across ICP-family condensing units. Confirm the MFD and voltage ratings stamped on your original capacitor before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage. Always discharge the capacitor across its terminals with an insulated resistor before touching it.
Access — Remove the service/electrical panel on the condensing unit.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Disconnect the spade terminals, loosen the mounting clamp, and lift out the old capacitor.
Install — Secure the new capacitor in the clamp and reconnect wires to the matching HERM, FAN, and Common terminals per your photo.
Test — Restore power, call for cooling, and confirm the compressor and fan start promptly.

Signs You Need a Replacement

Compressor or fan hums but will not start, or starts slowly.
Capacitor top is bulged, leaking, or domed.
Measured MFD is more than 6% below the rated value.
Unit trips the breaker or short-cycles on hot days.

How do I replace the capacitor on my ICP WPH3602000RKA1 | 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?
