What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model YK042GC2 — 2.5 MFD 370/440V | 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 YK042GC2 — 2.5 MFD 370/440V | 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 #1064218) provides the steady phase shift that keeps the fan or auxiliary motor running on your ICP/Tempstar/Heil YK042GC2 system. Rated at 2.5 MFD, it ships with the OEM mounting clamp for a clean, secure install. A weak or failed capacitor is one of the most common HVAC service calls: the motor it feeds may hum but not spin, start slowly, overheat, or trip on overload. Bulging tops, leaking oil, or a reading far off the 2.5 MFD rating all mean it's time to replace. This direct OEM part restores rated microfarad output and proper motor starting torque.

Access — Remove the service panel to expose the capacitor and its mounting clamp.
Document — Photograph all wire connections before disconnecting.
Remove — Pull the spade connectors, loosen the clamp, and lift out the old capacitor.
Install — Secure the new capacitor in the clamp and reconnect each lead to the matching terminal per your photo.
Test — Restore power and confirm the motor starts smoothly and runs at full speed.

Frequently Asked Questions

Does this Capacitor fit my ICP YK042GC2 — 2.5 MFD 370/440V | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP YK042GC2 — 2.5 MFD 370/440V | 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 YK042GC2 — 2.5 MFD 370/440V | 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.
