Sometimes, they fail shortly after one year of ownership. Some potential safety situations may not be foreseen or covered in this manual. The start relay is the tiny black box that looks like an ink cartridge attached to the compressor. To keep this from recurring, ensure nothing is blocking the air vents, and replace the gasket if it is damaged. 5 What should the resistance of an ohmmeter be? This can be due to excessive loads, poor airflow or lack of superheat. . But this post is especially about the check compressor motor winding. The meter should read 120V AC. When the contactor completes the circuit, the run winding WILL actually draw really high amps for a split second (first electrical cycle) until the inductive reactance kicks in. A technician needs to check a single-phase compressor. Now, check the WiFi connection on your refrigerator. Step three is not that complicated but it is delicate. Your email address will not be published. These were models manufactured between January 1, 2014, to December 31, 2017. That happens because the flame is heating [], Fenestration is a fancy architectural term that means openings in the outside of the building. You will see this word a lot when you read ACCA manual J or when you are doing a manual J load calculation. Bear in mind that when your refrigerator is in the Display/Demo mode, it will be on but wont cool. 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. Does a short to ground exist? Gain access to our free AOP (Ask a Professional) Section to get real answers for your questions. Meaning to say there is no continuity. 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. As you place the testing ends on the copper pipe, move them around. BUT, if I understand correctly, the smallest Ohm reading should be found between COMMON and START. 2. Some leak detectors, including the INFICON Stratus, measure concentrations in PPM (parts per million). Mostly we use white or black color for common. As we know, the wear and tear on the compressor are due to constantly going on and off. This method is good for detecting grounded or open windings and windings that are suspect (resistance too high). The lowest resistance will be found between the run(R) to common(C). Here, the piston will move along this linear track to reduce the loss of energy and minimize friction. Leak detectors come in many varieties, including heated-diode, ultrasonic, and infrared; each type has unique maintenance needs. If they do, the compressor is shutting down. Does the unit have a TXV, and if so is it equipped with a kickstart? While an inductive load does have SOME resistance when de-energized that can be measured with an ohmmeter, the majority of the electrical resistance only shows up once the current is applied. However, the NFPA and IEEE have recommended a ground resistance value of 5.0 ohms or less. For a 460-volt motor, the pass/fail threshold value would be 1.46 megohms, or a current leakage rate of 500 V dc / 1,460,000 ohms 342 microAmps. Then you need to check your sh and sc to make sure your refrigeration side didn't have anything to do with your comp failing. Consequently, the leakage causes the refrigerant to build up excessive pressure, putting stress on the compressor. The control panel will beep. I guess since it's a brother of a friend the reality of it is he's trying to save money by not calling a company out that would want to get paid full price so he bothers you in your free time. The reason LG refrigerator compressors fail is like different bridges linking together. Touch the meter leads to the corresponding leads on the start capacitor, red to positive and black to negative. Otherwise, change the motherboard. 1" Throat High Frequency Driver. Now if your compressor terminals reading shows the same as in the above post then your compressor winding is not burned or if its shown different reading between common, start and run then your compressor winding is burned. This shows an open pantry sensor. A pressure relief valve is installed on the compressor to relieve excessive high-pressure buildup (450 psi and above) and prevent damage to the compressor and other A/C components. 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. Taking ohm readings on compressor terminals I'm getting 0.8, 20, 20.8. . Press J to jump to the feed. MI mechanical license since 1998, 99% residential experience.
