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. Unlike the traditional compressor that stops running when the compartment becomes cold, then kick-starts again, the linear compressor works differently. This shows an open pantry sensor. Alternatively, use a multimeter to test it for continuity. Therefore, when you remove the compressor leads (wires) from the plug to check resistance through the compressor windings, the pressure of the Freon can launch the plugs with as much as 20,000 pounds of force. comp failures aren't limited to just electrical failures. Otherwise, replace the part. If it is hotter than usual, it is a sign something may be wrong with the compressor. If you continue to use this site we will assume that you are happy with it. If you want to reset the compressor on your LG refrigerator, all you have to do is to reset the thermostat. The math still doesn't line up perfectly because even in a heat strip, the resistance increases as the temperature increases, but it's in a much smaller fashion than in a light bulb. The cause is usually due to frost building up on the fan. Since you cannot buy parts of the ice maker individually, you have to replace the ice maker assembly. if that shows different results then the compressor winding is burned or crossed. intelegent person Pls send me detail information about compressor dryer. Motors, solenoids, contactor coils, lightbulbs and heater elements are examples of electric loads. The compressor should be replaced. If you need more clarification, the video below would be helpful. Right, it's just I would expect a much lower resistance with a shorted winding. The work of the thermostat is to send voltage to the cooling system: compressor, evaporator fan, and condenser fan. If the compressor on your LG refrigerator will not start, here are the common culprits: The overload relay is a part of the compressor that keeps it from overheating and causing a fire. Compressor burnout is a very specific mode of failure that may be caused by high temperatures in the motor windings or discharge area of the compressor. There was a backorder on compressors for a short time. Note that you can only do this if you have an idea of what the resistance of what youre measuring ought to be. To check the working condition of the thermistor, use a multimeter to test it for continuity. Alternatively, you can use a multimeter to test the functionality of the overload relay. You can defrost the fan manually by unplugging the refrigerator for some hours.

The Never Clean condenser coils are in locations where you cannot easily access them. High temperatures break down the motor winding insulation, which may cause a loss of electrical resistance and result in a short to the ground or even an open winding. Purchase a new compressor motor if your ohm readings are high. So, they measure their voltage, grab a calculator, and calculate. The internal overload is wired in series with both the start and run winding which prevents the compressor from coming on. Let a service technician handle this repair. When the condenser fan is faulty, it cannot cool the coils. This is because the dirt prevents the dissipation of heat from the refrigerant. Additionally, when the refrigerator does not cool properly, check the compressor. Therefore, before you can access the compressor, you will need to gain access to the rear of the refrigerator first. If the range is too high, then the reading will stay on 0 or close to it. To stop these error codes from repeating, level the unit according to the leveling guide, and free the air vents. Consequently, the compressor starts to overheat. However, you need to know when the noise is a cause for alarm. Bear in mind that when your refrigerator is in the Display/Demo mode, it will be on but wont cool. If that is the case, remove the objects causing the entanglement. Other times, it will be several clips. High Ohms on Compressor 2,887 views May 10, 2017 This compressor had very high Ohms. To test for a short to ground, set a multimeter to the ohms scale and touch one lead to a clutch coil terminal and the other to a ground point on the compressor. In the case that any of the tests above fail, you need to check the compressor posts themselves. John '92 SSP (ex-FHP 797) stock - SOLD Save However, this can only be true if your refrigerator does not have the Never Clean condenser coils. 240 volts. C - R = 4 Ohms. Available 8 ohms. But if you want to check your compressor yourself then this post is for you. Just disconnect the refrigerator from the power source for 2 minutes, then plug it back in. If you check the clutch coil resistance and it is outside of 3.5 to 4.0 ohms, it would be a good idea to contact the compressor supplier and see what they say. Your compressor ohms readings are too high. Ensure the refrigerator is not on demo or display modes. Caps and relays look ok, found high resistance when ohming the compressor. So, with this, your refrigerator runs with little current, making the electricity bill lower. Which is the most sensitive range of ohms? If it is, change it. Finally, the resistance between run and start should be the sum of S to C and R to C. Remember, there should be a measurable resistance through each winding. Your Compressor is old and is experiencing normal wear and tear, which makes it stop working. This can be due to excessive loads, poor airflow or lack of superheat. That is because the repair is sensitive and requires experience. 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. Required fields are marked *. Otherwise, the refrigerator will require a service repair. The other two sides should be 0. The reason this happens is that the thermostat monitors the temperature within the refrigerator. It is never the same. C to S was 2.4, others were 11.5 ohms. It indicates zero ohms when there is no resistance between the test points. That should clear the error code. 1" Throat High Frequency Driver. You have to change it. System pressure is too high. In these conditions your Compressor will overheat and can fail. That means that its job is to convert electrical energy to an electromagnetic force. Sorry for the bad news. Fenestration loads include heat losses and gain through windows, doors, skylights, etc., and they can make up [], 2023 - HVAC School | All rights reserved. They are junk. Including recorded tech training, interviews, diagnostics and general conversations about the trade. Whatever the case, once the evaporator fan stops working, the refrigerator will stop cooling. ASD-1001B. Yep, I agree with you. I did in between fix a power cord that might have had a short. If the cooling system runs short on refrigerant, you may need to hire a service technician to fix it. The thermostat ranges from 0-9. This shows that there is a transmission error between the display and the control board. The leveling of the refrigerator can also affect the sealing of the doors. Participate in over 40 different forums and search/browse from nearly 3 million posts. I had a look at the data sheet of the compressor (NJ2212GK) and the resistance rating for the start winding is 7.25 ohms, the rated resistance value for the run winding is 1.95 ohms. He labels the three terminals "A," "B," and "C" and takes resistance readings of the windings. Last year alone, at the dollar stores I do, I had many many burned up compressors. Were dealing with electricity here; dont mess around! So, for a faulty condenser fan, you need to replace it. Also, check any pin to ground to see if you have a short to ground. Run Winding 243V 2.6 = 93.4A Start Winding 243V 4.2 = 57.85A So, they do not require you to clean them manually. To test the compressor on your refrigerator, follow these step-by-step guide below: Unplug the refrigerator from the power outlet, shut off the water supply, and pull the appliance away from the wall. Please select the application form language. If the start relay makes a rattling noise, it is most likely faulty. You can also call it the overload switch or overload relay. High side max pressure (Ps) 46.1 bar: High value of nominal voltage at 50Hz [V] . In the case above, a compressor/fan motor/contactor coil, etc., is an inductive load. Adjust the temperature controls to the setting you desire. Unless you are an engineer, it's much easier to measure what you have on a functioning component rather than attempting to calculate amperage and wattage based on voltage and ohms. 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. So, when the temperature thermostat is faulty, it will most likely keep the compressor running. The essence is to effectively keep the freezer and refrigerator compartments cool. To determine if the compressor receives voltage from the motherboard, test the wire connecting to the compressor using a multimeter. Older relays looked a bit different than the solid state one below, but pulled off pretty much the same way. The compensation price started from $50 to above $3,500. Some potential safety situations may not be foreseen or covered in this manual. The compressor is behind the bottom rear access panel on your refrigerator. Motor winding resistances of the single door direct cooled refrigerator compressor is as below:Common running = 29 ohmCommon starting =32 ohmRunning-starting = 60 ohmCan we conclude that compressor ok? Remember to exercise extreme caution because on a 90-degree day, the pressure in a de-energized R410A system can be approximately 275 psi and when a compressor has shorted out, the plug can overheat and become soft. 6 Which is the most sensitive range of ohms? Remove the test light, set the multimeter to DC volts, and touch the leads across the switch pins or test . I was starting to second guess myself because I couldn't picture it. In some cases, we also have to watch for automatic zeroing capabilities. In the case of the bulb above, we know its cold resistance is 12.2 ohms, but by working Ohm's law backward, we can also tell that its HOT resistance is 142.57 ohms, which means that the hot resistance is 11.6 times higher than cold in this particular instance. Next to the liquid . Once the wires are disconnected, you can ohm out the wires, plug and compressor as they all require an inspection. Firstly, you will need two resistors of 1000-ohm. Thus, it does not require so much energy to operate. Turn the range down on the ohmmeter 1 step at a time to test the circuit. But if the compressor has received the power supply and still not working or running then maybe its starting capacitor or relay is not working. VerticalScope Inc. All Rights Reserved.
