What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WFSR100C060A1 — 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 WFSR100C060A1 — 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 genuine OEM run capacitor kit fits the ICP/Tempstar/Heil WFSR100C060A1 and includes the 35 MFD 370V oval capacitor (part number 1184895) and its mounting strap (part number 1014315). A run capacitor provides the continuous phase shift a single-phase motor needs to run efficiently — it stores and releases energy each cycle to keep the motor torque smooth. A weak or failed capacitor causes the motor to draw high amperage, overheat, hum without starting, or trip on thermal overload. Capacitors are the single most common HVAC failure because they are exposed to heat and constant electrical stress; capacitance naturally drifts downward with age. Always verify the measured microfarad value with a meter — a capacitor reading below about 90% of its rated 35 MFD should be replaced. The included oval strap secures the capacitor inside the control box.

Compatibility

Built for the ICP / Tempstar / Heil WFSR100C060A1 and compatible across ICP-family units calling for a 35 MFD 370V run capacitor (part 1184895). A 440V-rated capacitor of the same microfarad value may also be substituted; confirm the MFD value matches exactly.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the control/electrical access panel.
Document — Photograph all terminal wiring before disconnecting; capacitor terminals are not interchangeable.
Remove — Safely discharge the capacitor across its terminals with an insulated resistor, then remove the leads and loosen the mounting strap.
Install — Secure the new capacitor with the strap and reconnect each terminal exactly per your photo.
Test — Restore power and confirm the motor starts immediately and runs at normal amperage.

Signs You Need a Replacement

Motor hums but will not start, or starts slowly.
Measured capacitance is below the rated 35 MFD.
Capacitor top is bulged, leaking, or visibly burst.
Motor overheats or trips on thermal overload.

Frequently Asked Questions

Does this Capacitor fit my ICP WFSR100C060A1 — With Strap | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WFSR100C060A1 — 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 WFSR100C060A1 — 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?

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.
