How to check the error log

Samsung ovens do not have a user-accessible error log. The code stays on the display until you fix the cause or cut power at the breaker for 3 minutes; if it returns after a reset, treat it as real.

Clear the log after a repair so you can tell whether the fault has really gone.

Questions

Is it worth repairing?

Depends.

to / ts during startup or during use?

Samsung range and wall ovens report to / ts any. That timing is a useful clue when narrowing the cause.

Can I keep using the machine with to / ts showing?

Usually you can finish the drink you are making, but do not ignore it — the underlying fault rarely heals itself. Work through the cheap checks first.

Will to / ts clear on its own?

Rarely. A reset or power cycle is worth one try, but to / ts with a "hard" difficulty rating almost always means a failed component that has to be replaced.

How long does the repair take?

This one is a bench repair for most owners — the teardown, test and reassembly are the bulk of the work, not the part itself.

How reliable is this page?Samsung’s UK support page lists some oven codes, such as C-d0, C-20, C-21, C-22 and C-F0 to C-F2. For codes not on that page the meanings come from third-party sources and are lower confidence. Model revisions can differ: if your machine behaves differently, tell us. See our editorial policy.
