Whirlpool Fridge Capacitor (W10662129)

The Whirlpool Fridge Capacitor helps the refrigerator’s compressor start and run by storing and releasing an electrical charge at startup. It supports steady compressor operation so the sealed system can circulate refrigerant and maintain proper cooling. Capacitors can fail from heat exposure near the compressor, age-related electrical breakdown, voltage spikes, or moisture intrusion. A weak capacitor may still work at times but struggle under load, while a failed capacitor may prevent the compressor from starting. Common signs that point to a capacitor problem include: Refrigerator is warm while the interior lights and controls still work Compressor does not start, or starts briefly and stops Repeated clicking sounds from the compressor area as it tries to start Humming followed by a click, then a pause, repeating in cycles Intermittent cooling that comes and goes without changes to settings Burnt odor or visible damage on the capacitor housing, such as bulging or cracking
