Best Kenmore Refrigerator Compressor Relay Switch

Is your Kenmore refrigerator humming but not cooling? A silent fridge can be just as troubling. The heart of your refrigerator's cooling system, the compressor, relies on a small but crucial component: the start relay. This seemingly simple device is often the culprit behind cooling failures, especially in Kenmore refrigerators. Understanding its function and how to address potential problems can save you from costly repairs or premature appliance replacement.

The compressor start relay for a Kenmore refrigerator is a critical component for starting the compressor motor. It provides an initial surge of power, allowing the compressor to begin its cycle of compressing and circulating refrigerant. Without a functioning relay, the compressor won't start, leading to a warm refrigerator. Imagine it like the starter motor in your car: it gives the engine that initial push to get going.

The specific design of a Kenmore refrigerator compressor starting device has evolved over time, moving from mechanical to more modern electronic variations. Early models used a mechanical relay, which relied on a physical switch to engage the starting winding. Current Kenmore refrigerators often utilize a solid-state relay, offering greater reliability and quieter operation. Understanding these distinctions can help you diagnose and address any starting issues effectively.

The start relay plays a crucial role in the overall operation and longevity of your Kenmore refrigerator. A faulty start relay can lead to compressor overheating and eventual failure, a significantly more expensive repair. Identifying and addressing a malfunctioning start relay quickly not only restores cooling but also protects your investment in the appliance itself. Regularly checking the condition of this component can prevent major headaches down the line.

Common issues with a Kenmore refrigerator's compressor starting mechanism include a clicking sound coming from the relay, the compressor failing to start entirely, or the refrigerator cycling on and off frequently. These symptoms can point to a failing relay, but it's important to rule out other potential problems before replacing the part. Checking the power supply, thermostat, and overload protector can help pinpoint the exact source of the issue. Sometimes, a simple cleaning of the relay’s contacts can resolve the problem.

If the relay is suspected to be faulty, testing it with a multimeter is recommended. A multimeter measures the electrical continuity and resistance across the relay terminals. This simple test can definitively confirm whether the relay is functioning correctly. Several online resources provide clear instructions on how to perform this test safely.

Three benefits of a properly functioning Kenmore refrigerator compressor starting device are: consistent cooling, prolonged compressor life, and energy efficiency. Consistent cooling ensures food stays fresh and prevents spoilage. A functional relay reduces stress on the compressor, extending its operational life. Lastly, a properly working start relay prevents the compressor from cycling on and off excessively, minimizing energy consumption and reducing your electricity bill.

If your Kenmore refrigerator compressor start relay is malfunctioning, replacement is often the best course of action. Before starting, unplug the refrigerator from the power outlet. Locate the compressor and the attached start relay, usually clipped onto the side. Carefully remove the wires from the old relay and connect them to the new one, matching the terminals precisely. Secure the new relay and plug the refrigerator back in.
