What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WAMA36004AT2 — 35+5 MFD 440V | 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 WAMA36004AT2 — 35+5 MFD 440V | 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 202300320025) is the factory replacement for the ICP/Tempstar/Heil WAMA36004AT2 3-ton condensing unit. A dual run capacitor provides the continuous phase-shift needed to run both the compressor (HERM terminal) and the outdoor condenser fan motor (FAN terminal) from a single component. Rated at 35+5 MFD and 440V, it stores and releases electrical energy to keep both motors turning efficiently. When a run capacitor weakens or fails, the compressor may hum but not start, the condenser fan may stall, the unit may trip the breaker, or you'll see hard starting and short cycling on hot days. This kit includes the OEM mounting strap (201270390202) so the capacitor seats securely in its bracket.

Specifications

OEM Part Number	202300320025
Included Hardware	201270390202 (Strap, Capacitor)
Type	Dual Run (round)
Brand	ICP / Tempstar / Heil

Compatibility

Designed as the direct OEM fit for the ICP/Tempstar/Heil WAMA36004AT2 condensing unit. The same dual run capacitor is shared across many 3-ton ICP-family outdoor units. Always confirm the MFD and voltage rating printed on your existing capacitor before ordering — a 440V capacitor safely replaces a 370V unit of the same MFD.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker. Verify zero voltage with a multimeter, then discharge the old capacitor across its terminals with an insulated screwdriver.
Access — Remove the condenser service panel to expose the electrical control area.
Document — Photograph all wires on the HERM, FAN, and C terminals before disconnecting.
Remove — Pull the spade connectors off, loosen the mounting strap, and lift out the old capacitor.
Install — Seat the new capacitor in the bracket with the included strap, then reconnect each wire to its matching terminal per your photo.
Test — Replace the panel, restore power, and verify the compressor and condenser fan both start promptly.

Signs You Need a Replacement

Compressor hums or buzzes but won't start
Condenser fan spins slowly or only after a manual push
Visible bulging or leaking at the top of the capacitor can
Intermittent cooling, short cycling, or tripped breakers in hot weather

Frequently Asked Questions

Does this Capacitor fit my ICP WAMA36004AT2 — 35+5 MFD 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WAMA36004AT2 — 35+5 MFD 440V | 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 WAMA36004AT2 — 35+5 MFD 440V | 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?
