What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WFAR120D066B2 — 35 MFD 370V OEM with Strap | 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 WFAR120D066B2 — 35 MFD 370V OEM with Strap | 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 35 MFD, 370V run capacitor (OEM part number 1184895) is the factory replacement for the ICP/Tempstar/Heil WFAR120D066B2 and ships with the matching oval mounting strap (OEM part number 1014315). A run capacitor provides the phase-shifted current that lets the motor start and run efficiently. As capacitors age they lose capacitance, bulge, or short — leaving the motor unable to start, humming, overheating, or cycling on its overload. A weak capacitor is one of the most frequent causes of a motor that buzzes but will not turn. This OEM-spec unit is rated at 35 microfarads and 370 volts in the oval form factor secured by the included strap.

Compatibility

Engineered as the OEM replacement for the ICP/Tempstar/Heil WFAR120D066B2. The included oval strap (1014315) secures the capacitor in the original mounting location. Confirm the MFD (35) and voltage (370V) against the label on your existing capacitor before installing — a 440V capacitor of the same MFD is also acceptable, but never substitute a different microfarad rating.

Installation Guide

Safety First — Disconnect power at the breaker, verify zero voltage with a multimeter, then discharge the capacitor across its terminals through an insulated resistor.
Access — Remove the control or blower compartment service panel.
Document — Photograph every terminal connection before disconnecting.
Remove — Pull the spade connectors, loosen the mounting strap, and lift out the old capacitor.
Install — Secure the new capacitor with the included oval strap and reconnect each lead to its correct terminal per your photo.
Test — Restore power and verify the motor starts cleanly and runs without humming or overheating.

Frequently Asked Questions

Does this Capacitor fit my ICP WFAR120D066B2 — 35 MFD 370V OEM with Strap | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WFAR120D066B2 — 35 MFD 370V OEM with Strap | 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 WFAR120D066B2 — 35 MFD 370V OEM with Strap | 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?
