What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model YG042GC1 — 2.5 MFD with Clamp | 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 YG042GC1 — 2.5 MFD with Clamp | 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 genuine OEM 2.5 MFD round run capacitor with mounting clamp (part number 1051476) supplies the steady phase-shifted current that keeps the condenser fan motor on the ICP / Heil / Tempstar YG042GC1 spinning smoothly. A run capacitor stores and releases energy on every AC cycle to give the single-phase motor the rotating field it needs for efficient, continuous operation. When the capacitor weakens or fails, the fan motor may hum and fail to start, spin slowly, overheat, or trip on thermal overload — leading to high head pressure and poor cooling. The included clamp secures the round can to the unit so it cannot vibrate loose.

Compatibility

Direct OEM fit for the ICP/Heil/Tempstar YG042GC1 condensing unit and other Carrier-family outdoor units that originally used capacitor 1051476. Confirm the MFD rating and part number on your existing capacitor before ordering.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, verify zero voltage, then safely discharge the capacitor with an insulated resistor across the terminals.
Access — Remove the control-box service panel on the condenser.
Document — Photograph the terminal wiring before disconnecting.
Remove — Disconnect the leads, loosen the mounting clamp, and lift out the old capacitor.
Install — Secure the new capacitor in the clamp and reconnect the leads exactly per your photo.
Test — Restore power, call for cooling, and confirm the fan starts instantly and runs at full speed.

Signs You Need a Replacement

Condenser fan hums but won't start until spun by hand.
Fan runs slow or cycles off on overload.
Bulging, leaking, or burst capacitor can.
Measured capacitance is well below the 2.5 MFD rating.

Frequently Asked Questions

Does this Capacitor fit my ICP YG042GC1 — 2.5 MFD with Clamp | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP YG042GC1 — 2.5 MFD with Clamp | 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 YG042GC1 — 2.5 MFD with Clamp | 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.
