What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model YK048G — 440V | 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 YK048G — 440V | 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 round run capacitor (Part #1051476) provides the phase shift that starts and runs the outdoor fan motor on your ICP YK048G condensing unit. Rated at 2.5 MFD / 440V, it stores and releases the charge that keeps the motor spinning efficiently. Capacitors weaken with heat and age — a failing one causes a fan that hums but won't spin, slow or intermittent starts, or a motor that overheats and trips. Replacing a bulged or out-of-tolerance capacitor restores full motor torque and protects the windings.

Installation Guide

Safety First — Disconnect power, verify zero voltage, and discharge the capacitor across its terminals with an insulated resistor.
Access — Remove the control-panel service cover.
Document — Photograph the terminal wiring before disconnecting.
Remove — Slide the leads off the spade terminals and loosen the mounting clamp.
Install — Secure the new capacitor in the clamp and reconnect the leads per your photo.
Test — Restore power and confirm the fan starts promptly and runs smoothly.

Frequently Asked Questions

Does this Capacitor fit my ICP YK048G — 440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP YK048G — 440V | 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 YK048G — 440V | 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.
