Product review (5 stars): Expensive solution to simple problem
This part replaces the following:

W10189966, AP4360738, W10112113, W10155109, W10188476, W10201186, W10121508, W10051176, W10130544, 8576385, W10112112, W10104830, W10051171, 8576386, W10104820, W10121311.

The real problem is that all of the above part numbers were faulty.  Whirlpool placed countless units into service under it's own name, Maytag, and the Sears Kenmore name, with bad parts.  So every unit which contained any of the above part numbers have to be serviced.

It is in fact, a very simple fix.  Truth be told, the consumer should not have to bear the cost of correcting this mistake.  If that many cars were sold with defective parts, there would be a recall.

The story on my machine was that the machine would stop, and display the "F1" error code.  Anyone who is mechanically inclined, with access to simple hand tools, should be able to replace this part in under 30 minutes.

On my machine, I needed a Phillips screwdriver, a nut drive, and wire cutters.  The units cover was fastened by 3 Phillips screws.  The control board was secured by a screw which required a nut driver.  I forget which size.  But if you have a set of nut drivers, you should be able to locate one in the right size.  In my unit, a few of the wires were held together by a zip tie.  I cut the zip tie off to make it easier to handle everything, but you don't have to.  Do not worry too much about the unplugging all the harnesses, and not remembering where to plug them back.  Simply put the new unit next to your existing unit, and transfer the wiring one harness at a time.  All of the harnesses are different sized, all of the wiring on a harness will be the same color, and the unit will have markings indicating which color bundle of wires goes where.

What really upsets me is that the poor senior citizens, or single moms, who have nobody handy around, will have to pay out of pocket for a repair person to come to their home to fix it for them.  In most jobs, parts accounts for 1/3 of the service bill.  An unscrupulous technician could easily bill someone into the hundreds of dollars to perform this service call.  In my area, an appliance repair tech could charge up to $300 for the service call, about $200 (including State Sales Tax) for the part, and maybe even spend an extra hour or tow doing diagnostics to run the bill up to $600 or $700.

Diagnostics?  Sure.  Before he takes the machine apart, he'll attempt to run it a few times to verify that the described problem exist.  Which means he stands there, turns the machine on, then waits for it to stop with the trouble code showing.  He documents the time into the wash cycle, and which part of the cycle the machine stopped at.  Then he repeats this about three times, to confirm the reported condition and to make sure that there aren't any other problems.

After the technician replaces the control board, he may go over the rest of the machine.  A detailed technician will actually want to take the panel off the back.  He or she will then inspect all moving parts for signs of wear, clean out any accumulated dirt, lint, et cetera, lubricate points of contact and movement.  And finally recommend replacement of worn moving parts.

Next, the technician will verify the repair.  This means that he will run the machine for several wash cycles to ensure that the new part works, and no other repair work is needed.  This gives you the peace of mind that when he leaves, you will have a working unit.  And he will also know that he will not have to return to correct something that he should have taken care of while he was on the premises.

What does that all cost?  How much do you have to pay for a house call which could last half the day?  Would it be better to disconnect the unit, and bring it to the repair shop and let them work on it there so that you don't pay for the "house call"?  Think about it like this:  if a mechanic works on your brakes, don't you want him to inspect the entire braking system as opposed to simply putting on new pads?  If he doesn't check, how do you know that you have clean brake fluid, your master cylinder isn't leaking, all the brake lines are in good condition?  What if he just replaces the brake pads, and doesn't machine or replace your rotors?  Or even worse, not test drive the car after installing the new brakes?

Is all that work really necessary?  I believe that when you do a job, you do it right.  I spent 4 hours on my machine, doing exactly what I described above.  Of course, I am not charging myself, and you may not want to spend your own time, or pay that much for the work to be done by someone else.  Just buy this part, install it, and be done with it.  If something else breaks, then worry about that later.
