What does SE error code means?

"Some say it is a SE is a sensor error. Others, a Key short error.

The SE error code indicates that you have a stuck key on the control keypad or a failed electronic control board. A technician will need to diagnose and repair this type of failure. Microwaves are inherently dangerous to service. Internal high voltage components can retain a lethal electrical charge even when the microwave is completely unplugged. A microwave shielding test must be performed on the unit to detect any possible radiation leakage following any internal component repair. These are the reasons that I recommend having a technician service the microwave."

My microwave did that but also showed SE one-two-three-four intermittently ,it was evidently a loose connection on the touchpad ribbon to the board. Remember You must push the ribbon firmly into the connector before closing the clamp.

Umm microwaves don’t use radiation to cook food!! They use “microwaves” absolutely no radiation other than standard electro magnetic radiation which is emitted by every single electronic product everywhere!!

My Samsung Microwave had a SE / 5E error. All I did was open it up, disconnected all the cables tot he board, removed the front panel then I used a few earbuds to clean the board and a paper towel to clean the ribbon. Finally I left the microwave open and everything disconnected overnight. The next morning I put everything back together and all is working fine

Is e s same as s e ?
