Most of the time the panel buttons stop working because grease gets between the outer panel and the contacts underneath. Disassemble the door and if you need to carefully peel back the outer panel, use some paper towels to remove the heavy grease, then using a Q-tip and some rubbing alcohol clean the back of the panel and the surface contacts on the board, then re-assemble.

Look into the connector and see the point of contact which is visible of the metal contacts. Now the carbon tracks must be on the side of the metal contacts of the connector. In this case it is possible that while you pulled out the flexible stip cord there is damage on the strip , can be that the carbon tracks were damaged and so it does not contact. if so use a carbon track pen to line the tracks so as to contact.
Reversing the cord will not do any damage as there will not be any contact.
finally make sure that the PCB( printed circuit board) was washed with petrol and brushed properly and then DRIED before the unit was powered or else it can damage the processor.
Check the connection leads that were removed and make sure that it went to the correct postion.
Sometimes the touch pads refuse to work once it is disturbed as it might get damaged in the carbon tracks within.

I have samsung microwave model number ME 1240SC. my front panel touch screen is not working properly, when i press the keys it is not working. so i think i need to replace the touch screen. so please...


That model does not user a touch screen, it actually uses a standard membrane keypad.

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 that doesn't work, leave it unplugged for about 5 minutes. Then try it again.

If it's still not responding, I would suspect your membrane keypad has failed.

Is it possible that some spray cleaner accidentally got into the controls?

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

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

The keypad may be damaged or worn out, or control unit may be damaged.

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.

If you wanted to order a new membrane switch / keypad, the part number is DE34-00145F and you can order it from the Pros here. They're our favorite supplier.

Otherwise, this is a pretty standard 1200W microwave, and you may find it better to simply replace it instead of repairing it.

It may be a glitch that can be corrected by a hard reset. Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

It may have gotten moisture, contamination, or grease inside, which can happen if one cooks on the stove top without having the microwave's hood vent fan on.

It may simply need repair.
