What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WFSR080B048A2 — 25 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 WFSR080B048A2 — 25 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 oval run capacitor is engineered for the ICP/Tempstar/Heil WFSR080B048A2 gas furnace. Rated at 25 MFD and 370 volts, it provides the steady phase shift that keeps the blower motor running smoothly and efficiently. A run capacitor stores and releases electrical energy on each cycle; when it weakens or fails, the motor draws excess current, overheats, and eventually stops. Common failure symptoms include a blower that hums but won't start, a motor that runs hot, intermittent operation, or a bulged/leaking capacitor can. Kit includes OEM part 1176131 (CAP RN OV 370V 25 MFD) and 1014315 (oval capacitor mounting strap) for a complete, secure replacement.

Compatibility

Direct-fit replacement for the ICP/Tempstar/Heil WFSR080B048A2 furnace. Also compatible with many ICP-family blower assemblies that call for a 25 MFD / 370V oval capacitor. Always confirm the MFD and voltage rating 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. Discharge the capacitor with an insulated resistor before touching terminals.
Access — Remove the furnace blower compartment service panel.
Document — Photograph all wire connections before disconnecting.
Remove — Loosen the mounting strap, note terminal markings, and pull the spade connectors off the old capacitor.
Install — Secure the new capacitor with the included oval strap and reconnect each wire to its matching terminal per your photo.
Test — Restore power and confirm the blower starts promptly and runs without humming or overheating.

Signs You Need a Replacement

Frequently Asked Questions

Does this Capacitor fit my ICP WFSR080B048A2 — 25 MFD 370V Oval | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WFSR080B048A2 — 25 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 WFSR080B048A2 — 25 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.
