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 with mounting clamp (part 1095021) provides the starting and running phase shift for the fan motor on the ICP / Tempstar / Heil WPA3424000RKC1 heat pump. Rated at 2.0 MFD, it stores and releases the charge that keeps the condenser fan motor spinning efficiently. A weak or failed capacitor is one of the most common no-cool / no-fan service calls: the motor hums but won't spin, runs hot, or the unit trips on overload. A bulged top, leaking oil, or an out-of-spec microfarad reading all confirm replacement.

Compatibility

Direct-fit replacement for the ICP / Tempstar / Heil / Comfortmaker WPA3424000RKC1 condenser fan circuit. The 2.0 MFD round capacitor and clamp are common across many ICP-family outdoor units; confirm the MFD rating stamped on your old capacitor before installing.

Installation Guide

Safety First — Disconnect power, then discharge the capacitor across its terminals with an insulated resistor and verify zero voltage with a multimeter.
Access — Remove the control-panel service cover on the condenser.
Document — Photograph the capacitor terminal wiring before disconnecting.
Remove — Pull the spade connectors, loosen the round 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 and confirm the fan motor starts immediately and runs smoothly.

Signs You Need a Replacement

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?
