Kenmore Mod# 110.87892601 / Ser# MW0603330

Complaint was that as soon as power button is pushed display lights up then immediately goes dead, (like power button was pushed again).

When I went out to check it, it worked perfectly, checked everything and could not get it to repeat the problem.    Told them most likely it would do it again and to call me when it did.

It did, the very next day they tried to use it and they could get it to run at all.

When I arrived this time it in fact was do what they said it was.

I got it to work by immediately pushing the start button after pressing the power on button, then it worked fine again, after disconnect and reconnecting all wires to power cube and user interface the problem came back again a few times then it started working ok again.

Tried to put it into diagnostics to see if any error codes are stored and when you do the key dance it will not go into diagnostics.  The display and all indicators light up as they are suppose to then all shuts down again immediately just like the when trying to turn it on.

I checked the power cube, it is getting the correct voltage, (118 volts AC), and putting out 5.26 volts DC to the user interface.

There are only two connections from the main CPU board to the user interface, the two wire 5 volt power supply and the three wire data line.  When the 5 volt power supply is removed from UI it won't respond to anything and nothing lights up as expected.   When the three wire data line is remove it will throw a F70 error after setting for a couple of minutes, (which is communication link problem which would be expected).  With the three wire data cable disconnected you get the same response from the UI when trying the diagnostic entry key dance.

It appears from all I've done it has to be a bad user interface board, can anyone that may have ran into or seen this type of failure before let me know if I'm on the right track?

I've run into this problem before. Discovered through the monkey-method that the touchpanel was the problem. Turns out this is not uncommon on these machines.

You are correct, I went to look up parts after making this post and find the model number I wrote down is wrong.

It should be 110.87892601

And also after looking up parts I see there are two control boards in the user interface/control panel.

The left side control with the power button and turn dial plus some other functions, Part# 'W10023340 Electronic Control' and

The right side control with the display and some other control options, Part# 'W10164491 User Interface, Right'.

Samurai, Thanks for confirming I'm on the right track.  But now I need a clue as to which of the two boards would be the problem.     My thinking would be the left side control with the power button and turn dial, but that is just a wild guess at this time.

Another question, anyone know which control boards are included in the 2nd year parts only warranty on the 'Sensor Smart Electronic Board', or if this one would even have the 2nd year part only on boards?  It was manufactured Feb/2008 and the only online user manual that I can find is dated 2006 which states the 2nd year board warranty, (I know in or around 2006 is when the manufactures started the flat one year parts and labor warranty only).

There are 4 boards in this unit.
1) Power Cube, (supplies 5 volt DC to control panel/user interface)
2) Main machine control, (all relays to control heater/motor/light etc.)
3) Electronic control, (turn dial/power and other user functions)
3) User Interface, right, (all LED displays and some other option buttons)

NCSU, Was the problem you had the same as I described and changing only the right side interface, (LED display and option buttons), corrected the problem?

Samurai, could you give a little more input on what board you have replaced to solve what problem and if there are any service bulletins pertaining to this problem?

Thanks

Hey, RegUS, any chance you have a service manual for this dryer?

Willie, we're not given enough information from the manufacturer to definitively pinpoint which board is bad. It's not a shortcoming on our part as technicians-- it's lack of detailed technical information from Whirlpool. Without that, the only way to know which board is bad is by field experience, as NSCU offered, or the plug n' pray method: replace a board and pray it's the right one. Since I don't have the time to screw around with multiple visits, in these kind of cases, I use the nuclear option and replace the entire touchpanel. Problem solved. On the very next trip. And the customer is happy, too. In my experience, customers who own these needlessly over-electronified, sorry-excuse-for-a-dryer are higher income and are more interested in having their dryer fixed taco-pronto than they are in saving a couple of shekels on a repair. So, until I get better technical information from Whirlpool on their crappy electronics, that's how I'll continue to play it.

Thanks Samurai, that's kind of what I was figuring you were going to say something like that, (but more like it was under warranty so you just replaced all the boards).

I was hoping someone that has gone down this road before with plug and pray method would have figured out what board was actually causing the problem.

Looks like I will just order both boards, (since only one supplier that I use has only 1 of each board in stock), I will try the right side board first per NCSU and if that takes care of the problem, I won't even open the other one and should be able to return it.

Again, anyone with a real service manual, (not just the tech sheet), for this unit???

Thanks RegUS, but that doesn't help any either.   This manual is for the Whirlpool branded unit and it only has one main user interface control board in the console, not two like the Kenmore I'm working on.

Or it might be that this manual is from 2006 and the dryer I'm working on is a much newer model, (Build date 2/5/2008).

I have had an issue similar to this but with the washer. After numerous conversations with tech line and several boards later I came to the conclusion that neither the tech. Line nor the tech. Sheet were correct. The voltage tests that tech. Sheet was showing for the CPU was not correct and tech line wasn't sure....long story short this unit was under warranty so the lady got a new machine....but I agree ....replace the whole thing

A follow up to close this out and hopefully save others from an embarrassment like this.

Ordered both User Interface boards.  Installed right/display interface first since it has all the computer chips on it and looks like the one that would be doing any processing.  Plugged in and little speaker was just little chirping away like a little birdy, so installed other, (left interface with dial), and plugged back in and got the same thing.  Wouldn't even power up and flash instantly off like the old one.

Quite embarrassing when you have over $200 in boards and it hasn't fixed the problem, (good thing this is a friends dryer and they were very understanding).

So put all old boards back in and got it back to the condition it was when I started.  Speaker wasn't chirping anymore and when power is pressed every thing lights up then  instantly turns off.  So back to diagnostics.

Checked power cube again, had 5.23 volts when sitting, and then I find my problem, with meter still connected to 5 volt DC output and watching meter as I push power button see voltage drop to around 1.5 volts each time power is pressed on then goes back to 5.23 volts when all display goes back out.

I say, must be a bad power cube.  Pulled power cube board out of plastic housing and there it is staring me in the face!!!!!   A BLOWN 100 uF 250 volt capacitor, top all bulged out and inner paper hanging out and sighs of it's juice in the bottom of the plastic housing.

Instead of replacing the the power cube for another $70.00 I purchase a 100 uF 350 volt capacitor, and install it and it all works again.

The reason for the miss diagnose was when first checking, this was an intermittent problem.  Was doing as described when I arrived but before opening up and testing after pushing a few buttons it started working for me and I check the power cube and of coarse it was showing the correct voltage.  It just wouldn't go into diagnostics for me and when the next day the customer called back and said it's doing it again I just assumed from all the help here and all I had tested it had to be one or both of the user interface boards.

The problem had to be the capacitor was just on it's last legs and had enough life to make it work those last few times for me and the customer even got it to work a few more times over the week waiting on the boards but the last 4 days it completely quite and they couldn't get it to work again.

I figure from all testing and all the old boards in the machine and the power cube repaired diagnostics also works now, it makes since the diagnostics wouldn't start up because it would draw to much of a load for the bad capacitor to handle in diagnostic because diagnostics would put a much heavy load on the power cube since it lights up all lights and displays.  The bad capacitor had just enough guts left to intermittently operate just the few lights and controls needed for normal operations until it completely died.

Great find, Willie, domo for posting it! :dude:

Those electrolytic capacitors are troublemakers on all appliance electronic boards; they're the reason the display dims on range ERCs. For others who come along and read this, here's what those capacitors look like (unbulged):
