What MFD capacitor do I need for my ICP AC?

The correct replacement for ICP model WPG3242040LKB1 — Oval & 2 MFD Round | 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 WPG3242040LKB1 — Oval & 2 MFD Round | 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 capacitor assembly for the ICP/Tempstar/Heil WPG3242040LKB1 packaged gas/electric unit includes the original oval run capacitor (clamp-mounted) and the 2.0 MFD round run capacitor (P/N 1171552 and 1095021). Capacitors provide the phase-shifted starting and running torque that the condenser fan motor and compressor require. Rated at 440V, they charge and discharge on every cycle, making them among the most failure-prone parts in any air conditioner. A failed capacitor is the most common cause of a unit that hums but won't start, a fan that turns slowly, or a compressor that trips on overload. Replacing with the exact OEM parts restores rated microfarad output and protects your motors from premature failure.

Installation Guide

Safety First — Disconnect power at the disconnect box and verify zero voltage with a multimeter before touching any terminals.
Access — Remove the electrical service panel from the unit.
Document — Photograph all capacitor wiring before disconnecting anything.
Remove — Discharge the old capacitor across its terminals with an insulated resistor, then unclip the mounting clamp and pull the spade connectors.
Install — Seat the new capacitor in the clamp and reconnect each lead to its matching terminal per your photo.
Test — Restore power and confirm the fan and compressor start smoothly with no hum.

Signs You Need a Replacement

How do I replace the capacitor on my ICP WPG3242040LKB1 — Oval & 2 MFD Round | 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.
