What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WFSR120D060A2 — 35 MFD 370V 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 WFSR120D060A2 — 35 MFD 370V 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 OEM kit includes the 35 MFD / 370V run capacitor (part number 1184895) and its oval mounting strap (part number 1014315) for the ICP / Tempstar / Heil WFSR120D060A2 gas furnace. The run capacitor provides the phase shift the blower motor needs to start and run efficiently. A weak or failed capacitor causes the blower to hum without starting, start slowly, overheat, or trip on thermal overload — which in turn leads to poor airflow, short-cycling, and high-limit lockouts. Testing a suspect capacitor with a meter on the capacitance scale confirms whether it has drifted out of its rated 35 MFD range.

Compatibility

Built for the ICP/Tempstar/Heil WFSR120D060A2 furnace blower circuit and related WFSR-series furnaces using the same 35/370 blower capacitor. Confirm the rating on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter.
Access — Remove the blower-compartment service panel.
Document — Photo the capacitor terminal wiring before disconnecting.
Remove — Discharge the capacitor across its terminals with an insulated resistor, then unfasten the oval strap and lift it out.
Install — Secure the new capacitor in the strap and reconnect each lead to its matching terminal per your photo.
Test — Restore power and confirm the blower spins up to full speed without humming.

Signs You Need a Replacement

Blower hums but will not start, or starts sluggishly
Capacitor case is bulged, leaking, or domed on top
Measured capacitance has drifted well below 35 MFD
Furnace trips on high-limit from weak airflow

Frequently Asked Questions

Does this Capacitor fit my ICP WFSR120D060A2 — 35 MFD 370V Oval | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WFSR120D060A2 — 35 MFD 370V 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 WFSR120D060A2 — 35 MFD 370V 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.
