Jenn Air model JJW3430WS00 control issues

[AWSHandy]

The control is unresponsive after a cooking cycle is done. The power needs to be shut off then on again.  Then it responds.  Is this a function of cooling off or temp sensors. I have the tech sheet.  It does not seem to run a self test.  When in diagnostic mode it lets you turn various functions on and off.  Is there a way to run a self test and get error codes.  Currently, no error codes are coming up.  Any help appreciated.  Thank you.

sounds like your control board is going bad,  usually anytime something works after rebooting, the control is going to be the issue

You would need to go through the tech sheet and check voltages after it fails.

It's likley that it needs a new control panel (I've changed a few now), but they're about $2,000 and most of the colors are out of stock, so it's better to be certain. Maybe you'll get lucky and it's one of the other boards. 8-)

Error codes aren't likely to be useful if the board is dying. If it can't keep the lights on, it probably can't detect and store error codes either.

I looked up the parts on this.  There is a control panel, a console, and an electronic control board.  I have NO idea how to determine which one might be the cause. AND these are VERY expensive components that when opened from packaging are non returnable.  ?????

I use the wonderful technique I learned from Son of Samurai. 8-)

When the service information doesn't have a clear method for determining which board is bad, I quote all that it could possibly be.

If the customer goes for it, I order them all, then install the most likely suspect first. In this case, it's the main board with the display & touch panel. If that doesn't do it, I install the other board(s). If the first board fixed it, I give the customer the good news and return the unopened second/third board. Otherwise, I keep installing boards until it works and the repair costs exactly what I quoted.

There really is no way to know which one is bad because the service docs contain the infamous "replace this and if it still doesn't work replace that", and if this is the board I'm thinking of it actually talks over a fiber optic cable and there's no documentation on how it talks, what it's saying or how to monitor it. 

However I'm not getting stuck with a $2000 board. Or a $300 board. Or the $160 board. So if the customer won't authorize the worst-case scenario, it's not my problem. I'll happily collect my service call and leave.

The down-side is that the customers get a little annoyed and has sticker shock, but that's not my problem. I didn't build the oven and there's no 100% certain way to diagnose it with the available information, so I'm not taking chances at owning a $2K board.
