Error codeSE / -SE-
ApplianceMicrowave
Quick answer
SE (shown as -SE-) is the key short error on current Samsung microwaves. Reset power first; request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so SE / -SE- may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
SE (-SE-) is the key short error on a Samsung microwave.
When a Samsung microwave displays SE, which can appear as -SE-, it is flagging a key short error. The entry is part of the table for current Samsung microwaves.
Clearing the code
Take power away first: pull the plug or turn off the circuit breaker. Moisture on the unit needs time to dry. With no moisture involved, simply wait 60 seconds before switching power back on.
If SE appears again, the next step is to request service.
Related display codes
A key problem can be mistaken for a touch problem, so compare it with TE, the touch communication error. The additional-error pair is also close by: E-X2 (additional short error) and E-X1 (additional open error).
