Samsung Range S-01 — What It Means & How to Fix It
Also shown as SO1 on some models.
S-01 is Samsung's safety shutoff: the oven ran continuously at its set temperature for hours and the board switched it off. It's a protection feature, not a fault — turn it off, remove the food, and use it normally.
What this code means
S-01 is Samsung's safety-shutoff code: the oven kept operating at or near a set temperature for longer than its timed safety limit and the control board powered down to prevent anything running unattended indefinitely. The limits are generous — Samsung lists roughly 16 hours below 105°C, 8 hours between 105°C and 240°C, and 4 hours above 245°C — so S-01 almost always follows a forgotten roast, a proofing run left on, or a warmed dish forgotten overnight. Samsung's own documentation calls it 'not a system failure.'
Samsung's official information-code documentation lists S-01 specifically as a safety shutoff for prolonged operation at temperature, with the time limits above, and says to switch the oven off and try again. Model number is on the frame behind the storage drawer or the oven door frame.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Oven left running at temperature for many hours | Very common | Yes — turn it off |
| Long, low-temperature hold like proofing or warming | Common | Yes — restart when ready |
| Oven set above 245°C for 4+ hours | Common | Yes — lower the setting |
| Intermittent control issue if it repeats with normal use | Less common | No — technician job |
What you can try yourself
- Turn the oven off and remove the food. S-01 is the board protecting the unit after a marathon run — nothing is broken.
- Restart the oven normally for your next cook. A single S-01 needs no other action.
- If the oven was running at its maximum setting, choose a slightly lower temperature or finish with a timer so the code can't trip mid-cook.
- An S-01 that appears during ordinary, timed cooking is unusual — that points at a control issue worth a technician's look.
When to call a technician
- S-01 appears during short, ordinary baking runs, not long unattended ones.
- The oven shuts off repeatedly at the same point in a normal cycle.
- The display behaves erratically alongside the code.
Typical professional repair cost: No repair cost — safety shutoff is expected behavior; a recurring control fault that needs a board would run $200–$450 including labor.
Frequently asked questions
Did my oven break when S-01 appeared?
No — the code exists precisely to stop a long-running oven before anything else goes wrong. Samsung's own materials explicitly say S-01 is not a system failure and to simply restart.
How long does an oven have to run before S-01 trips?
Samsung's stated limits: about 16 hours below 105°C (like a low proofing hold), 8 hours between 105°C and 240°C, and 4 hours above 245°C. Normal roasting never gets close.
Can I disable the safety shutoff?
No — and you wouldn't want to; it's a fire-safety feature for forgotten loads. If you need a very long hold, break it into segments by restarting the oven partway through.
