The Whirlpool W10873801 Refrigerator Compressor Start Device is a critical electrical relay and overload protector combination that plays a pivotal role in the refrigeration cycle by providing the initial electrical boost required to start the compressor. Without a functioning start device, the compressor, which is the heart of the cooling system, cannot begin its operation, leading to a refrigerator that fails to cool or maain temperature. This component ensures the compressor receives a powerful but momentary surge of electricity, overcoming its initial inertia and allowing it to pump refrigerant efficiently. This start device also incorporates an overload protector, which safeguards the compressor motor from damage due to overheating or excessive current draw. When the refrigerator's cooling system encounters issues, or simply due to age and wear, the start device can fail, leading to symptoms like a clicking sound from the compressor area, the compressor attempting to start but failing, or the refrigerator not cooling at all. Replacing this part ensures the compressor can operate as ended, restoring the appliance's ability to preserve food effectively and preventing further, more costly damage to the compressor itself. is a critical electrical relay and overload protector combination that plays a pivotal role in the refrigeration cycle by providing the initial electrical boost required to start the compressor.
