I have questions on my washing machine. It doesn't spin, agitate, or drain
unless I have to unplug the power supply and replug it back after 30
minutes. Then after running for a while, it deads again. Do you have any
ideas what causing to these problems? I am thinking of replace the control
electronic board, which it costs about $200 not including the labors. Its cost is almost the same as replace a new machine. My washer machine is Kenmore and its model is 11020052992. Thanks for your help. Seng S #### Sir Charles W. Shults III Jan 1, 1970 0 It sounds to me like the processor or some other chip (such as a driver chip) is heating up and then failing. Allowing it to cool lets it resume operation. To troubleshoot it, you should have a can of freeze spray and open the box. When the failure occurs, try spraying the chips and when they cool down, see if it starts working again. Here is a thought- if the CPU is dying, then it will likely require rebooting to continue operation. If a driver or output chip is dying, then it should resume operation without a hitch. Now, are you able to replace these parts if you find the faulty ones? Many are surface mount these days. Cheers!

If it's the controller chip, it's proprietary and the only replacement you can get is the whole circuit board so he doesn't even need to worry about component level repair. Depending on the level of cooling needed to get it to run again and the amount of space available, he might be able to get away with gluing on a transistor heatsink T #### the Wiz Jan 1, 1970 0 Sengthum said: I have questions on my washing machine.

Motor overheating from excessive load, such as a sock in the pump or a partially
blocked drain hose?
