Whirlpool WP12555902 Refrigerator Start Device Relay & Overload
Product Description
The Whirlpool WP12555902 is a critical component of your refrigerator's compressor. This functions as both a safety mechanism and a regulator. The overload prevents the compressor from overheating by cutting off the power supply if it senses a dangerous temperature increase. This avoids lasting harm to the motor. The device additionally works as a relay, restarting the compressor once it has cooled to a safe operating temperature. The WP12555902 is a small electrically connected device that is housed within the refrigerator's sealed system. This measures the compressor's current draw, which rises as the motor works harder. If the current exceeds a safe limit, the overload will trigger, disconnecting power to the compressor.
