SE
Samsung SE on a microwave: a touch key is held down
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On a Samsung microwave, SE means the control detected a touch key pressed for more than 10 seconds. Samsung says to unplug the unit and clean dust or water off the panel; if it returns, contact the service centre.
Safety first
Stop and check this first
- Do not take the microwave's outer cover off to look for the fault: inside there is a high voltage capacitor that can hold a lethal charge even when unplugged. The magnetron, door seals and safety interlocks are for authorised service only.
Safe checks you can perform
- Reading the code and the panel
- Unplugging and cleaning the keypad
- Normal use with a load inside
Leave these tasks to a qualified professional
- Do not attempt this professional task: Keypad and connector check
- Do not attempt this professional task: Operating test after the repair
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Keypad and connector check
What they doThe authorised technician checks the touch panel and its connection to the board following the service manual, with the unit disconnected and high voltage discharged as the procedure requires.
They must show youthe test that rules the keypad in or out, such as each key's response or the connector condition.
In writingthe cause found and, if the panel is replaced, its part number and the reason.
Operating test after the repair
What they doAfter the work, the technician runs a cycle with a load and presses every key to confirm the code does not return.
They must show youthe microwave heating a load and every key responding.
In writingthe test done, the result and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Reading the code and the panel
- Who:
- you, no tools.
- How:
- note whether it shows SE, -SE- or C-d0 and look for drops, grease or anything touching the keypad.
- Result that matters:
- that the code belongs to this family and whether the panel is wet or covered.
- If you see moisture or something resting on it:
- remove it and move on to cleaning.
- If the panel is clean and clear:
- cleaning is still Samsung's first step, but note that it was already clean.
- Evidence to keep:
- photo of the code and of the panel.

Unplugging and cleaning the keypad
- Who:
- you, with a soft dry cloth.
- How:
- unplug the microwave, clean the control panel until it is dry and wait a minute before plugging it back in.
- Result that matters:
- whether SE clears on power-up and the keys respond.
- If it clears:
- it was dirt or moisture on the keypad.
- If it returns without touching anything:
- rule out dirt and move on to service.
- Evidence to keep:
- note of the time, what you cleaned and the result.

Normal use with a load inside
- Who:
- you, with a microwave-safe container of water.
- How:
- place a microwave-safe cup of water inside, set a short time with the keys and watch. Do not run it empty.
- Result that matters:
- that it accepts the keys and finishes the cycle without SE.
- If it works and the code stays away:
- the problem is solved.
- If SE returns when pressing or by itself:
- note when, and call Samsung service.
- Evidence to keep:
- short video of the panel showing SE if it comes back.

What it means
Samsung UK groups SE, -SE- and C-d0 under one definition: the control registers a touch key pressed for more than 10 seconds. Samsung Canada calls it a key short error. Dirt or moisture on the panel, something resting against it, or a fault in the keypad or its connection can cause it. That is why the code alone does not prove the panel must be replaced: clean it and test again first. The table is Samsung UK's microwave guide; check your model's manual to confirm the code means the same.

Symptoms and causes
Probable causes · in order
- Water, grease or dust on the panelCommon
Samsung asks you to clean dust and water off the button. It fits if the code appeared after wiping with a wet cloth, heavy steam or splashes; it clears once the panel is dry.
Evidence: Samsung Microwave Oven error codes - what do they mean?
- Something pressing a keyPossible
An object leaning on it, a magnet or a finger held on the panel counts as a long press. You can tell because the code does not return once nothing touches the keypad.
Evidence: Samsung Microwave Oven error codes - what do they mean?
- Keypad or connection faultPossible
If SE returns with a clean, dry panel, Samsung points to the service centre: the keypad or its connection may be reporting a press nobody makes.
