Product review (5 stars): Product works, but the repair job may be difficult if you are not experienced
The product worked, but this was not an easy repair for me to make.  I have a Kenmore front-load washer from 2009 (model number 417.48102701).  The controls started "acting crazy" (LEDs were randomly blinking, settings changing by themselves, etc.) and a quick Google search helped me identify the problem as being caused by a bad control board.  I found a forum that linked to the service manual for the washer, so I bought this board and replaced the bad board.  The good news is that the washer works again. The bad news is that it was a long, frustrating repair job which took something like 2 1/2 hours total.  I went through three iterations of disassembling-and-reassembling the machine.

The service manual was written for people who already know what they're doing, whereas I had essentially no experience fixing appliances.  The biggest problem was that after i re-assembled the washing machine, the program knob was badly misaligned, in the sense that the pointer on the knob didn't point to the correct program listed on the console.  So I had to partially disassemble the machine, and then troubleshoot the issue with the control board hanging down by its wires, while the machine was plugged in (possible electrical risk here).  I more-or-less figured out how to align the knob, but then re-assembly was surprisingly difficult (the shaft didn't seem to want to go into the knob properly, and I had to fiddle with the thing).  When I finally reassembled, the pointer was off by one click.  So I disassembled again, tried to fix it, and reassembled (again, with difficulty).  Still off by one click.  At this point, I gave up, and I now run the machine while keeping in mind that the pointer points one click to the right of the actual setting.

In addition to the above difficulty, I experienced several other, smaller issues, such as problems getting parts to snap in place properly (or unsnap when disassembling).  I'm sure that if I were more handy, I wouldn't have had these same frustrations.  Or, at least, I'd solve them quicker.

Anyway, the point I'm trying to make here is that if you want to fix your own washer, you should probably be more experienced than I was.  Or maybe you can find a friend, relative, or neighbor to do it for you.
