Question about KitchenAid KHHS179L Convection/Microwave Oven

Open Question

KitchenAid touch screen display is fogged and loose

In Sept 2005 I bought a KitchenAid KHHS179L in Florida. A couple of years later the touch screen display fogged up though still readable. Is that from the humidity? Recently it came unattached from where it was adhered. It seems like the glue membrane dried up or something, but the square touch screen is loose. (still works). KitchenAid wants over $200 for the part. If I replace it, I don't see any screws to open up the housing where it sits.

KHHS179LSS-3 touch screen has stopped working. When I un-plug it and then plug it back in, I get a "Touch Error" message saying 'Y High Fail 255 95; Y HiLo Pass 255 0; Y Low Fail 255 0; X...

There is no reset other than unplugging the power for a minute then plugging it back in.

If this in under warranty I would contact the manufacturer via the information in your owner's manual for a free repair.

If for some reason you don't still have yours, you can download Kitchenaid / Whirlpool owner's manuals and installation instructions here.

If it's out of warranty, we repair these controllers for $39.95, or you can order an LCD assembly (part number ) from the Pros here or get a refurbished unit from us here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Touch pad will not respond to the touch. repair man wants to charge over $400 to fix it? this can't be right, what do you reccomend?

You guessed right- it isn't right. I think his price is based on the cost to replace the whole thing minus $100 or $200.
The touchpad is part of a board that may cost some bucks but not likely over $100 and replacing the failed one shouldn't take a blind man more than an hour; there are some housing screws to be removed, some board screws to be removed, one or two connectors to pull and replug on the new board.
If Kitchenaid wants more than $100 for the board, it is because they don't want to fool with repair items at all. I estimate that the finished board probably costs about $15 when it leaves the assembly line.
They really want you to donate yours to the landfill and buy a new one.

My KHHS179LSS-3 will not let you control microwave from touch screen un pluged unit plug back in touch error high fail low fail appears on screen

I was afraid I needed to replace the microcomputer when my KHHS179L touchpad was unresponsive. I was able to use the ADD A MINUTE feature, so I knew the unit worked. There had been a power outage of less than a minute to my home recently (I was unaware of this until I asked the kids if they had done anything to the microwave). I popped around on and really didn't find an easy solution-my favorites. I loaded and found the answer in the FAQ's. Although the control lock out icon was NOT LIT-apparently, that power surge locked my controls. By holding the stop button for 5 seconds once and then aagain a second time, miraculously, my touchpad was restored> HOORAY!

Buttons on microwave do not work at all

Yes. The time base is important.

You could unplug it and try it again, but it may not work.

Another model's manual says, "a 120 Volt, 60 Hz,
AC only, 15- or 20-amp fused electrical supply (or circuit breaker)
is required."

Error Code

F7 problems are usually caused by poor connections. I suggest to unplug the ribbon connector off the control board and cleaned the copper connectors using alcohol or with a pencil eraser. If that does not work the touch pad may be defective.
