What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WFSR120D060A1 — Single-Run Oval | 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 WFSR120D060A1 — Single-Run Oval | 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 is a genuine OEM single-run capacitor (370V, 35 MFD) for the ICP/Tempstar/Heil WFSR120D060A1 gas furnace. The run capacitor provides the continuous phase shift that keeps the blower or condenser fan motor turning smoothly and efficiently. When a run capacitor weakens, motors draw excess current, overheat, and fail prematurely. This kit includes OEM part 1184895 (capacitor, 370V/35 MFD) and the matching oval mounting strap, OEM part 1014315, so you have everything needed to seat the capacitor securely in the cabinet.

Compatibility

Designed as a direct OEM replacement for the ICP/Tempstar/Heil WFSR120D060A1 furnace. The 35 MFD / 370V rating is shared across many comfort-line air handlers and condensing units using the same blower motor. Always confirm the MFD and voltage rating stamped on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. A charged capacitor can hold a dangerous voltage — discharge across the terminals with an insulated resistor before touching.
Access — Remove the furnace service panel to expose the capacitor and mounting strap.
Document — Photograph all wire positions and terminal markings (HERM/FAN/C) before disconnecting.
Remove — Loosen the old oval mounting strap, slide the spent capacitor out, and transfer leads one at a time to avoid mix-ups.
Install — Seat the new capacitor in the included oval strap, reconnect each lead per your photo, and tighten the strap to the cabinet.
Test — Restore power and confirm the motor starts promptly and runs without humming or stalling.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my ICP WFSR120D060A1 — Single-Run Oval | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WFSR120D060A1 — Single-Run Oval | 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 WFSR120D060A1 — Single-Run Oval | 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.
