Unclip the black plastic cover at the left-hand side of the compressor, and wiggle it out. After you access the relay and compressor on your fridge, use a multimeter to test the ports to make sure it has a low resistance. I already publish a post about the start, run, and common identification guide on this blog. If your LG refrigerator compressor keeps running, it shows the compressor is bad. If you want to learn more about inductive reactance, please check out this article HERE. The following are tell-tale signs that the compressor of an LG refrigerator is bad: The compressor makes a humming sound and clicks on/off while it is running. Although it is uncommon for the compressor to be the cause of refrigerators not cooling, we cannot overlook it. Here is how to reset different parts of an LG linear compressor refrigerator: Open the door and long-press the freezer switch. Then they ohm out a residential compressor or other single-phase motor windings for the first time. A megger sends voltage through a cable and measures any current leakage in megohms (1,000 ohms). If you measure between the run winding and the start winding, you should get the sum of the other two readings. So, ensure you have tried troubleshooting the other components before coming to these. Only the control relay would operate. Whatever the case, once the evaporator fan stops working, the refrigerator will stop cooling. If it does not have continuity, then it is faulty. If your refrigerator has a shortage of refrigerant, there is a bigger problem; the gas is leaking. Example - C -S = 7 Ohms. This shows the ice maker sensor is disconnected, or the fan motor is malfunctioning. Your refrigerator may be due for a service repair. The thermostat ranges from 0-9. Basically, using a digital ohmmeter, you pull the compressor's relay and overload off its three terminals, then check the resistance between each of these three pins. Mountable in any orientation. However, it should not overheat. Compressors are equipped with internal overload devices which open on a rise in temperature. In addition, LG refrigerators with a linear compressor are better at maintaining a stable temperature within the unit. If you have an iPhone, subscribe to the podcastHERE, and if you have an Android phone, subscribeHERE. It starts up slowly and slows down when the refrigerator is cool enough. Refer to your owners manual for instructions on how to disable the display mode. If the range is too high, then the reading will stay on 0 or close to it. It is probably ice building up around the fan. If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. Its a good idea to approach leak detection with a plan, including starting high on the coil and moving down (because refrigerant is heavier than air and may set off the leak detector below the actual leak). With the system pressure lowered, it is now safer to remove the plug and test the compressor terminals directly. Use your multimeter in continuity setting, measuring the Ohms across 3 compressor terminals Common to Run should have the lowest resistance Common to Start should have the 2ndlargest resistance Run to Start should have the largest resistance Now connect one lead of the meter to the compressor common and the other connects the compressor uninsulated body place. Leak detectors come in many varieties, including heated-diode, ultrasonic, and infrared; each type has unique maintenance needs. Unplug the fridge and pull it away from the wall. So, close the refrigerator door tightly to ensure a good gasket seal. If they do, the compressor is shutting down. Watt's law is just as easy: With this newfound knowledge, the student walks confidently into the real world with two equations and some elementary algebra skills, expecting to be able to predict volts, amps, watts, and ohms using this secret knowledge.
