What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WFAR080B048A1 — OEM 1176131 | 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 WFAR080B048A1 — OEM 1176131 | 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 the genuine OEM 25 MFD, 370-volt oval run capacitor (part number 1176131) for the ICP WFAR080B048A1 gas furnace, supplied with its mounting strap (part number 1014315). The run capacitor gives the blower motor the phase-shifted current it needs to start smoothly and run efficiently. As capacitors age they lose capacitance, bulge, or leak, and a weak capacitor forces the motor to draw extra current, overheat, hum, and eventually fail. Replacing a marginal capacitor is one of the cheapest and most effective ways to restore proper motor performance and protect the more expensive blower motor.

Compatibility

Direct OEM replacement for the ICP WFAR080B048A1 furnace and other ICP-family units (Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite) using the 25 MFD 370V oval capacitor 1176131. A 440V-rated capacitor of the same microfarad value may also be used. Verify the MFD value on your old capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the switch and breaker, then verify zero voltage and discharge the capacitor with an insulated resistor before touching the terminals.
Access — Remove the blower-compartment service panel.
Document — Photograph the terminal wiring before disconnecting.
Remove — Pull the leads off the spade terminals and loosen the mounting strap to free the old capacitor.
Install — Secure the new capacitor with the strap and reconnect each lead to the matching terminal per your photos.
Test — Restore power and confirm the blower starts promptly and runs without humming.

Signs You Need a Replacement

Blower motor hums but will not start.
Bulged, leaking, or swollen capacitor top.
Measured capacitance well below the 25 MFD rating.
Motor overheats or trips on its internal overload.

Frequently Asked Questions

Does this Capacitor fit my ICP WFAR080B048A1 — OEM 1176131 | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WFAR080B048A1 — OEM 1176131 | 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 WFAR080B048A1 — OEM 1176131 | 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.
