What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3604090LKC1 — Clamp Mount | 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 WPG3604090LKC1 — Clamp Mount | 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 2.5 MFD round run capacitor provides the phase-shifted starting and running torque for the motor it serves in your ICP / Tempstar / Heil WPG3604090LKC1 packaged unit. It is a clamp-mounted round can capacitor that stores and releases electrical energy to keep the motor running smoothly and efficiently. As capacitors age they lose microfarad capacity, bulge, or short out — leaving the motor unable to start or causing it to hum, overheat, and trip on thermal overload. Replacing a weak capacitor is one of the cheapest and most common HVAC repairs. This part replaces OEM 1064218 (Clamp Capacitor, Round, 2.5 MFD).

Compatibility

Direct OEM replacement for the ICP Tempstar Heil WPG3604090LKC1 packaged gas/electric unit and related ICP-built brands such as Comfortmaker, Arcoaire, KeepRite and Day & Night. Always confirm the MFD rating stamped on your existing capacitor matches 2.5 MFD before installing.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter; discharge the old capacitor across its terminals with an insulated resistor before handling.
Access — Remove the service panel to reach the capacitor.
Document — Photograph all wire connections before disconnecting.
Remove — Loosen the mounting clamp and pull the spade terminals off the old capacitor.
Install — Secure the new capacitor in the clamp and reconnect each wire to its matching terminal per your photo.
Test — Restore power and confirm the motor starts immediately and runs without humming.

Frequently Asked Questions

Does this Capacitor fit my ICP WPG3604090LKC1 — Clamp Mount | Ships Today?

Yes. This is the factory-specified OEM capacitor for the ICP WPG3604090LKC1 — Clamp Mount | 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 WPG3604090LKC1 — Clamp Mount | 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.
