Good day sir/ma,am there are possibilities that the roach spray solution got on the contact terminals. DO NOT Turn it on, let it dry for several days. just to make sure. 3 days is enough. or if you choose to operate it, you must clean dry the circuit board. it requires that you dismantle it, clean the terminals dry and reassemble it again. this may not sound good. you may need to call your service center to be safe. hope this helps.

Put some of the COMBAT roach bait traps around the unit. when they come out and eat it they will die, put them under and around the unit. Buy extra, change them on suggested time intervals posted on the box. Place extra around kitchen to eliminate nests and spray kitchen cabinets too.

The right Half of the touch panel does not work and there is no power when start is pressed. Fans and lights work


Without a model number, I can only give you a general answer, but feel free to contact me with the full model number and detailed symptoms for a free estimate and/or do it yourself tips and part numbers, etc.

The problem is a failed keypad, which can occur due to manufacturing weaknesses, direct spraying of spray cleaners, heat or steam or grease accumulation due to failure to use the hood vent exhaust fan while cooking on the stove top, or just poor design.

Either way, you would have to replace the membrane keypad or outer door panel or control panel frame, depending on model.

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.

Chances are your membrane keypad has failed.

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.

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.

You can find helpful exploded view diagrams and order parts here.

I'd recommend that your bookmark this link to your favorites.


Otherwise, the keypad may be damaged or worn out, or control unit may be damaged.

Feel free to contact me directly (and please include your full model number from the tag in or on the unit) for a free estimate and free tips & do-it-yourself advice.

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 maybe an hour.

Then let us know if the hard reset does not fix it.

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.

Always spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

Always use the vent fan when cooking on the stove top to keep steam and grease out of the controls.

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

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.

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

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.

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.
