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 dual run capacitor (part 1173702) delivers the running torque for both the compressor and the condenser fan motor in the ICP / Heil / Tempstar WTH3482000RKA1 heat pump. Rated at 45+10 MFD and 370V in a round can, the 45 MFD section supports the compressor while the 10 MFD section drives the outdoor fan. A degraded run capacitor causes hard starting, a humming compressor that won't spin up, a stalled outdoor fan, and breaker trips. Replacing it with a correctly rated OEM unit restores reliable starting and full cooling/heating output.

Access — Remove the condenser control-box service panel.
Document — Photograph the HERM, FAN, and C terminal wiring before disconnecting.
Remove — Pull the spade connectors, loosen the mounting strap, and lift out the old capacitor.
Install — Secure the new capacitor and reconnect HERM, FAN, and C per your photo.
Test — Restore power and verify the compressor and outdoor fan start and run smoothly.

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.
