Hi good folks;hope you all had a great new year entrance;afamily member asked me to look at their wash machine Maytag MVWC465HW that is dead no leds turn on , i already took out main board but it's hard to troubleshoot due to the amount of wax covering all the board both sides,all fuses to the rectifier and filtering are good, tried to order it but no boards available and cost more than a new wash machine,so i'm trying to repair it at component level,i would appreciate if you could lid me the way any tip that will help me to fix the main board,there is no parts available for this mod# so it seems,power supply is bad somewhere, could be any component in the power supply, suspect U4 AC-DC Off-Line Switcher, Integrated MOSFET, but there are no Part # or marks on top of the Chip and is covered with WaX as the whole board which is hard to test components ,i have to scrape the wax around components to be able to test, so far don't see anything that maybe suspect besides U4 Mosfet but since no part # visible, it's similar to this one see link bellow ; ,don't know if it would fix the issue ,
So i'm stuck here with no info on the board,they sell other boards since it seems these boards are made by Whirlpool, but none for this machine with part# W10857311 ,and they costs as much as a new machine,wouldn't be wise to order an expensive board that not sure work with this machine,it's not worth it for a machine with 2 years and no assistance at all, if i can find the crupit component fine if not not worth it,thanks for trying to help, if you think of anything that i can check on this board please do,thanks in advance
