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.

Kitchenaid microwave model KHMS155L, starts randomly for 3 minutes with "PAN" flashing on display screen, than locks up with "F-2" message on display screen


"F2" means you have a shorting membrane keypad. The "Pan Heat" key is shorting.

On these models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

You can find helpful exploded view diagrams and order parts by entering your full model number* from the tag on the oven here.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.

My Kitchenaid microwave goes in "No Mains" mode when I utilize the back burners what is causing this I have the distance from the cook top 18-20 inches


My Whirlpool elite does the same thing when i have the exhaust running while cooking hot stuff. The phrase No Mains with a cartoon character jumping up and down on the lcd display. Tech support claims its low voltage. But my voltage is fine. Moving the plug to a different circuit doesn't help. Unplugging it for an hour seems to be a temporary fix because the problem happens again.

Keeps flashing a 'mains low' message on display. Have already tripped the main and the message in no longer constant but comes up whenever you try to use the unit.


What else is on the same circuit?? You may have to check on another outlet and see if you get the same message.If not ,that's the problem>too much pulling on 1 circuit.

Power source is fine turntable slow to move...no


In all likelihood the Magnetron has failed, or perhaps even the Power Supply is faulty. You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.Yes they are right.

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 fixya.com and really didn't find an easy solution-my favorites. I loaded kitchenaid.com 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!
