Kathy May 01, 2023 for Model Number LDF7932ST My noise filter board is completely burned out, what would cause this to happen?
1 Answer Kathy, Most of the time when you have burned sections on boards it is from loose connections. Read More...
Bryan February 23, 2023 for Model Number Lg dishwasher. My LG dishwasher is not powering up. I tested the old noise filter and there was no continuity on the middle terminals. I purchased a new one and installed , but I still have no power. I just check and the middle terminals on the new one have no continuity. Should they? Or is my new noise filter faulty. (0n 6201ec1006t) Or could it be something else ?
1 Answer Hello Bryan, the center tap is not used on the line noise filter so it will not show continuity, at this point you would need to check for 120v getting to the noise filter then out of the noise filter, then follow the wires to the main control board and again check for 120v going into the main control board, check the board for any signs of shorts or burn marks.

Jay December 02, 2022 Will testing for continuity on a noise filter 6201ec1006t be Sufficient for determining a good part or does power need to be applied? Saw a video on YouTube that showed testing from one leed to the other, stating there should be continuity across all 3 terminals. Can’t seem to find any other info other than applying power to test.
1 Answer Jay, An example would be part number AP5251356, when testing the terminals you will test the terminal on the white connector to the terminal on the red connector for continuity. Or VAC in to VAC out. Read More...
Terry October 03, 2022 for Model Number Fgmo205kfb Electronic noise filter is shorted. Power in, no power out. Obvious burn on the underside of board. Would this be the problem, or the result of the real problem? Don’t want to put in a new one just to have it fry immediately. Suggestion?
1 Answer Terry, You would need to check for any other burned or shorted components but you may have to replace this to determine. This filter is designed to absorb some power surges so this could be the only issue if a power surge was the cause. Read More...
Wayne August 11, 2022 for Model Number WM2101HW Been getting the PF code for about a week mid cycle and now no power at all. I'm trying to determine if the noise filter is good or bad. I have 120v at the power input on the top contact. On the output side the Top is 120v, middle is 60v, bottom is 0v. Should there be 120v at all 3 outputs on the noise filter or is this testing OK? Thanks!
1 Answer Wayne, If you have 120 Vac across the line and neutral going in and coming out of the noise filter then it is good and would need to check wiring of the unit and if the wiring is good then it would be a faulty main control board. The line and neutral should be black and white wires. Read More...
1 Answer Hello Chad, the manufacturer does not provide that information as the fuse is part of the line noise assembly and not considered replaceable, if the fuse has tested as open you should be able to see the fuse specs which are imprinted in the fuse end caps. Read More...
Michael January 24, 2022 for Model Number WM3360HWCA The noise filter on my LG WM3360HWCA has failed and I plan to replace it however I want to know if it is ok to do a test by using jumper wires to bypass the filter to see if the machine powers up normally? If the test shows the machine does not power up normally then I know I have a problem besides the noise filter. However I don't want to do the test if it will harm the machines electronics. Can I do the bypass test without harming anything? Thank you, Mike
1 Answer Hello Michael, line noise filters are very common on appliances using electronic control boards, they filter out possible incoming line noise, which could disrupt the electronics operation, also it filters out outgoing line noise the washer can generate in normal operation that could disrupt other electronics in the house. That all being said we cannot tell you that bypassing it even for testing will or will not cause a different problem in the appliance, specifically with the main control board. Read More...
Leo January 13, 2022 for Model Number LG direct drive front load Heard a snap sound followed by electrical burn smell, found the noise filter faulty by checking filter fuse. Ordered exact OEM replacement EAM60991301 .before installing i checked incoming voltage to be 120v at the filter connector.Installed the new filter and plugged unit in to see filter fault out. New filter also now shows open circuit across fuse. My question is, could a faulty main board cause this filter to short out? Does the filter not simply protect the unit from a power surge along with controlling the frequency noise? I rang out the hot and neutral lines from 120 v plug straight through to circuit board with no ground faults or open curcuits? What else could cause filter to fault out? Now removed main board and found fuse ok with no visable board burn marks? Not sure about now purchasing another filter and possibly main board.
1 Answer Leo, The filter board is not protecting the unit from a surge but is there to clean up any line noise that may come in through the power lines. Check for wiring that may be damaged and if there is not any damaged wiring then the main control board would likely be the issue. Read More...
Chris October 07, 2021 for Model Number LDF7774ST When I went to check line/noise filter, the wires were burnt and melted. Assuming I'll have to replace filter but this seems to be a larger problem. What would cause this.
1 Answer Hello Chris, I would verify the proper voltage is supplied to the unit and that there are no "dead shorts" in the unit. You will then need to replace the noise filter assembly 6201EC1006T. Read More...
Scott September 14, 2021 for Model Number LDF5545BD/00 Measuring between pins 3 and 8 on the Main PCB CN1 connector to the front panel/display PCB gives 5 VDC as expected. So this means my Main PCB is good and I should focus downstream, yes? Is the most likely suspect the front control panel/display PCB now? Is there another diagnostic test to confirm that? I don’t want to think about it being a short/open in a harness, but I’ll cross that bridge when I come to it… Thanks. —————— LG dishwasher LDF5545BD will not power up. Good power at breaker, junction box, and noise filter. The red LED on the PCB will light upon application of power. A voltage detector will indicate power on the right/back-of-unit side of the board about to the position of the LED, but then reads nothing on the left/front-of-unit side. Unsure as to what to go after next, whether it could be a partly bad PCB, maybe a bad harness somewhere, or the front control panel. Any advice as to what to troubleshoot next would be appreciated. Thanks. Scott for Model Number LDF5545BD/00 ANSWER Scott, if a 5vdc signal voltage will not leave the main control AGM76429503 to the user interface, then it has failed and would need to be replaced. The voltage can be tested using the main control connection CN1 from pin 8 to pin 3. Answered by AppliancePartsPros.com | Tuesday, September 14, 2021
1 Answer Scott, If you have power coming from the control board to the User interface but the interface is not coming on then it would be a faulty User interface. Read More...
