Here is how to reset different parts of an LG linear compressor refrigerator: Open the door and long-press the freezer switch. However, each make, model and size . Note that when the start relay is faulty, it cannot kick-start the compressor to work. The values add up correctly but the C-S seem quite high. Some technicians like to go a step further and check the amperage with an in-line amp meter. Run Winding 243V 2.6 = 93.4A Start Winding 243V 4.2 = 57.85A Otherwise, chat with our service technicians using the chatbox to your right. The top compressor pin is common, bottom left start, bottom right, run. Next, locate the three wires that power up the compressor the common, start and run winding and remove the wires from the contactor and the capacitor. A megger sends voltage through a cable and measures any current leakage in megohms (1,000 ohms). Check the connection between the duo, and reset it if there is a need. You have to join the one brown end of the resistor to the other gold end of the resistor. When the door is misaligned, it cannot cause a good seal. Furthermore, they may cause irreparable damages to the unit. This shows a component of the ice maker is faulty. Let a service technician handle this repair. If its tripped, you will read infinity (OL) between S to C and R to C, while seeing a measurable resistance between R to S. In this case, the compressor may be extremely hot to the touch. Let a service technician look at it. Since you cannot buy parts of the ice maker individually, you have to replace the ice maker assembly. Please enter a valid email address for yourself. Your email address will not be published. To reset the ice maker, open the ice maker compartment and remove the ice bucket. If the compressor passes the above tests, take a multimeter set to R x 10,000 (10K) and check each winding to ground. Hold the buttons for 5 seconds. The lowest reading should be below 10 ohms (this is the run winding). Any price and availability information displayed on [relevant Amazon Site(s), as applicable] at the time of purchase will apply to the purchase of this product. This shows an open pantry sensor. Where the normal operating current draw on a conventional compressor is somewhere between 1 and 2 amps, LR current could be somewhere north of 8 amps. Leave the appliance for 24 to 48 hours to normalize. Now connect one lead of the meter to the compressor common and the other connects the compressor uninsulated body place. If your ohm readings are above 30, it means that your compressor motor is likely faulty and you'll need to get it replaced. Loose and remove the overload protector. Save my name, email, and website in this browser for the next time I comment. Automotive Replacement Parts Switches & Relays Switches Air Conditioning Compressor Refrigerant Pressure Currently unavailable. Ensure you do not overload the shelves and drawers so they can fit right. Now you find and mark your compressor terminal. What Is the Linear Compressor In an LG Refrigerator? If you measure between the run winding and the start winding, you should get the sum of the other two readings. The overload protector keeps the compressor from overheating and causing a fire. If the dirt has caked up, use warm soapy water and a soft brush. Unfortunately, only a repair technician can fix it. Mostly in some compressors in which the common terminal is on the upper side then the left side will be start and the right-hand side will run the terminal, and Danfoss compressors in which the common terminal on the downside the right side will be the start terminal and left side will be run as I have shown in the below diagram. The condenser coils contain the refrigerant, and when they get dirty, they will not circulate the refrigerant efficiently. Switch your multimeter to ohms of resistance. You will be using the ohms function on you digital multimeter to troubleshoot the compressor, and having power applied to the circuit under test gives false readings and damages the meter..
