Samsung Oven Error Code LE
The control board is not getting the low DC voltage it runs on: the 12-volt supply has dropped under 9 volts. The fault sits in the transformer, the wiring to the board, or the board itself.
Common causes
- A loose wire between the low-voltage transformer and the electronic control board
- A damaged wiring harness dropping the DC voltage
- The low-voltage transformer has failed
- The electronic control board has failed
What to check, in order
- Switch off power at the breaker for at least 30 seconds and restore it; a sag after a power surge can set this code once.
- Unplug the range and reseat the connectors between the low-voltage transformer and the control board.
- Inspect the harness for damage and replace it if wires are broken or melted.
- If the wiring is sound, the transformer is replaced next; if the code still returns, the control board is at fault.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code LE, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
Questions people ask about LE
What does LE mean on a Samsung oven?
LE means: Low DC voltage error (below 9 volts DC). The control board is not getting the low DC voltage it runs on: the 12-volt supply has dropped under 9 volts. The fault sits in the transformer, the wiring to the board, or the board itself.
Can I fix Samsung LE myself?
Start yourself: the checks on this page cover the causes you can reach without opening the machine up. If they point to a faulty part, testing or replacing it is usually a technician job.
How do I clear Samsung LE?
Fix the cause first — clearing the code on its own brings it straight back. Then restore power and water, run the shortest programme, and watch the stage where the code appeared. If the programme finishes with no code, it is cleared.
