What -SE- means

On Samsung microwaves in the US, -SE- is the key short error. The control sees one of the keypad contacts as held down or shorted, even though nobody is pressing it. The owner typically sees -SE- on the display and a panel that ignores presses or will not start a cycle. Moisture on or behind the keypad is the most common reason a key reads as stuck, so drying the unit is the first thing to try.

Common causes of -SE-

Moisture under the keypad membrane
A key contact reading as pressed all the time
Keypad ribbon or connector contact
Control board input that stays latched

✓ One safe check you can try

1. Unplug the microwave or turn off the breaker. 2. If moisture got in, leave it unplugged until it has dried completely. 3. If it was not wet, wait 60 seconds. 4. Plug it back in or restore the breaker. 5. Do not press the keys hard or spray cleaner on the panel. If -SE- comes back, stop using the oven.

! Why to stop there

A key that reads as pressed after drying points to the keypad or its connection, and we confirm which
We check the ribbon contact and the board input rather than replacing the whole panel by guess
Nothing starts until you have approved a written price, and our work is warranted for 30 days

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

-SE--SE- questions

What does the S in -SE- stand for?

The message is listed as a key short error. In plain terms, a key on the panel is being read as shorted or stuck, whether or not anyone is touching it.

Will drying the microwave clear -SE-?

Often, yes, if moisture was the reason. Leave it unplugged until completely dry, wait a minute, and restart. If the message returns, the keypad or control needs testing.

Is it dangerous to leave it plugged in?

Not usually, but a stuck key can start or block cycles unexpectedly. We suggest unplugging it until it has been checked. Please leave it off until we have tested the keypad.
