It sounds like you may have spray cleaner or another liquid in the keypad.

I always recommend that users spray the cleaner on a soft cloth (not on the keypad itself) then wipe the control panel off.

Otherwise, the spray can get into the controls and lock it up or make it act odd.

I recommend a soft cloth since paper towels can scratch the plastic. Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.

If it does not dry out over time, it may need to be manually dried or blown out with compressed air.

Ideally the control panel (if it's an over the range model) or outer cover (if it's a counter top type) should be removed to aid in the drying.

The keypad may also be damaged and need to be replaced.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can get Samsung parts here.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

My Jenn-aire microwave says locked and has a picture of a padlock. I was microwaving bacon and had just put it some to cook ( my second batch per se) and everything was locked up. I tried pushing options...


Most likely you set a child lock (front panel lock) by holding a button too long (3 seconds). Without a model number, I can't be absolutely sure of the keypad lock for your Jenn-Aire microwave. Usually, the key will have a small padlock icon on it. Press and hold this key. On my microwave you press and hold Start to toggle the lock off.

On a Jenn-Aire JMW2430 and similar models, the Button Lock is activated by a several step process (More and Button Lock). However, pressing and holding the Start button will deactivate it.

I hope this helps.

MICROWAVE BUTTONS WILL NOT RESPOND TO ANY ACTION. IS THE MICROWAVE LOCKED.


Hi and welcome to Fixya, I am Kelly. This is usually from the Child lock being activated: 1. Touch STOP/CLEAR.

2. Touch and hold START/ENTER more than 4 seconds.

LOCKED will disappear and two beeps will sound.

Thanks for choosing FixYa, Kelly

I have accidentally locked my microwave oven (profile performance convection oven). I was cleaning the front. Can you tell me what to do?


Got you covered. Here you go:

Microwave - Explanation of the Child Lock Out Feature
Many microwave control panels can be locked to prevent accidental use or access by children.
There are two different ways to lock the control panel:
1. Press and hold the CLEAR/OFF pad for 3 seconds. The display will show "LOCK" and then revert to the time of day.
A small "L" will appear in the corner of the display as a reminder that the control panel is locked. If anyone tries to use the microwave, the display will show "LOCK".
2. On some models, press and hold the 5 and 7 pads simultaneously for 3 seconds.
To unlock the control: Repeat the procedure which was used to lock the control. (Press and hold the CLEAR/OFF pad for about 3 seconds or hold the 5 and 7 pad simultaneously for 3 seconds.)

Kenmore elite microwave oven displays "Locked" and will not respond


My Kenmore Elite microwave (don't have the model number in front of me) also mysteriously locked its own keypad (we were sitting in an adjacent room, heard a strange beep, and got up to find the LED reading "Locked."). I pressed and held down the Stop/Clear button for ~10 seconds and it returned to normal.

The control panel has the child lock turned on.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

If that doesn't work, try holding down the "0" pad for about 5 seconds.

Different models use different keys, so try "Stop/Clear" and other keys.

If all that fails, contact LG customer support at 1-800-243-0000 or http://us.lgservice.com

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?
