You can think of a refrigerator compressor as the heart of the machine. Knowing why can help inform you on whether or not you are in need of a repair or a completely new refrigerator.Ĭontinue reading to learn more about what a refrigerator compressor does and a few reasons why it may be failing. While this critical part lasts longer than most, it will eventually give out and fail. So, what does it mean if you hear a strange noise coming from your fridge? In most cases, the likely culprit is none other than the compressor. That is why it is so important that an unforeseen issue is resolved soon after it arises by our Grand Rapids appliance repair professionals. When it comes to the food we store and cook for our families, refrigerators are there to keep items fresh and safe to eat. If the fan is functioning correctly, you should feel airflow and hear the fan running.Our refrigerators are crucial to everyday home life. Also, check for proper airflow around the condenser coils at the back of the refrigerator. Test the new fan: Turn on the refrigerator and listen for the sound of the new condenser fan running. Plug in the refrigerator: Once you have completed the replacement and reassembly, plug the refrigerator back into the power source. Ensure they are properly aligned and securely fastened. Reassemble: Put back any covers or panels that were removed earlier to access the condenser fan. Double-check that the connections are secure. Use the screws or clips to secure it in place, ensuring it is properly aligned.Ĭonnect the new fan: Reconnect the wiring harness to the new fan, matching the correct wires or plug connections. Install the new fan: Take the new condenser fan and position it in the same location where the old fan was removed. Carefully remove the old fan from the refrigerator. Unscrew or unclip the old fan from its mounting bracket or housing. Remove the old fan: Typically, the fan will be held in place by screws or clips. It's important to note that testing a refrigerator compressor requires some technical skills, and if you're unsure or uncomfortable with any step, it's best to seek assistance from a professional appliance repair technician. Any rattling, grinding, or clicking noises could indicate a problem. A working compressor should produce a smooth, low humming sound. Listen for any unusual sounds coming from the compressor. Listen for sounds: Plug in the refrigerator and turn it on.If there is no continuity, it indicates a problem with the compressor. There should be continuity (a low resistance reading). Touch one probe to any terminal and the other probe to the metal casing of the compressor or a clean unpainted part of the refrigerator. Again, make sure the refrigerator is disconnected from the power source. This test checks if there is a continuous electrical path within the compressor. Check for continuity: Set the multimeter to measure continuity (ohms).If there is no resistance or an extremely high or low reading, it indicates a fault in the compressor. The resistance readings should be within a specific range provided by the manufacturer. Then, move one of the probes to the remaining terminal and record the resistance again. Locate the three compressor terminals, which are labeled "C," "S," and "R." Connect the multimeter probes to any two of these terminals and record the resistance reading. Disconnect the refrigerator from the power source. Measure resistance: Set the multimeter to measure resistance (ohms).If there is no voltage reading, it suggests an electrical issue. The multimeter should display the voltage (usually 110-120V or 220-240V) if the compressor is getting power. Connect the multimeter probes to the terminals, ensuring a good contact. With the refrigerator still unplugged, access the compressor terminals. Check power supply: Use a multimeter set to measure AC voltage to check if the compressor is receiving power.If you notice any of these issues, it may indicate a problem with the compressor. Look for oil stains, loose connections, or burnt components. Visual inspection: Inspect the compressor for any visible signs of damage or leakage. It is a cylindrical-shaped component with pipes connected to it. Access the compressor: Locate the compressor, which is usually located at the back of the refrigerator, near the bottom.Safety precautions: Before starting any work on the refrigerator, unplug it from the power source to avoid electrical shock.Here's a step-by-step guide on how to test a refrigerator compressor: Testing a refrigerator compressor typically requires some basic knowledge of electrical components and tools.
