Here is a previous answer that might be of help.......

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If it is still locked or goes into lock mode by itself, the "clear" key on your keypad may be shorting.
Here's how the child lock works on model FMV145:

Child Lock-Out
You may lock the control panel to prevent
the microwave from being accidentally
started or used by children.
To lock or unlock the controls, press and
hold CLEAR/OFF for about three
seconds. When the control panel is
locked, an "L" will be displayed to the
extreme right.

Frigidaire troubleshooting key pad seems to be stuck on child lock


If you have your owner's manual, read the section on how to disable the child lock. If that doesn't work the touchpad could be defective.

Cannot unlock the display panel


Elise,

So I'm understanding that the lock icon stays on no matter what you have tried. I would try pressing and holding the START/STOP button for 5-10 seconds to see if it changes. I don't know how long you've been leaving it unplugged for when you do unplug it, but i would suggest at least 3-5 minutes. If these don't work what I would do is either contact the manufacturer or maybe even a local authorized technician. This way they would be able to assist and possibly have some more suggestions or be able to find and solve the issue for you.

-Best regards-

We had a power outage and the display is blinking and there is no response to pressing any button


First, try unplugging the microwave for 2 to 5 minutes and then plugging it back in. Sometimes, a very brief power outage will be sensed by the control as an internal error and the control will lock itself out.

If it continues to blink and does not respond to key presses after this "hard reset", it is likely a portion of the control board could have been damaged from the power outage.

FYI ... the touch panel for this model is no longer available. I mention that because no response from any key press can also denote a shorted key pad.

MY displat shows a Child Lock problem. I find nothing in the manual about chikld lock. How do I unlock?


Manuals for some Thermador Microwaves are available here: http://www.thermador.com/trade/specifications-guides . Scroll down to Microwaves and select your model. Then press the link for Product Manuals and then choose the manual.

On the
MBES and MBESLFTD, the child lock feature is unlocked by pressing Settings 5 2 (touch each pad/number once).

If you have a different Thermador microwave, I'll check my stack of manuals for the specifics. (On a few other brands, the child lock can be toggled by pressing and holding the Start key. One of my other microwaves has a small padlock on the key to indicate the correct key. With that toggle, press and hold the key for 3-4 seconds or longer.)

I hope this helps.

LG LMVM2055SB over the range microwave keys not working


Is it possible someone may have sprayed cleaner directly onto the keypad area?

This causes moisture to get into the keypad and sometimes onto the control board.

This could mean that they control panel frame with keypad (membrane switch) would need to be replaced.

Can you give more details on the cleaning?
