Samsung NC on tumble dryer: lint filter problem
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Your Samsung dryer shows NC or NC1 because it detects a lint filter problem. Unplug it, wait at least 30 seconds, check that the lint filter assembly is fitted properly and start it again.
Safety first
Stop and check this first
- Check the filter and cover only with the dryer unplugged and without tools. Do not open screwed panels: there are mains connected parts inside.
Safe checks you can perform
- 30 second reset
- Lint filter assembly
- Internal heat exchanger cover (NC2 only)
Leave these tasks to a qualified professional

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.
Full drying test
What they doAfter the repair, the technician runs a complete drying cycle.
They must show youthe cycle finished without NC.
In writingthe test result.
Filter system diagnosis
What they doService checks why the control does not detect the filter or the cover correctly, with the dryer unplugged before it is opened.
They must show youthe fault reproduced with the filter and cover fitted.
In writingthe cause found, the reference of any replaced part and why.
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.
30 second reset
- Who:
- you.
- How:
- unplug the dryer, wait at least 30 seconds and plug it back in, as Samsung instructs.
- Result that matters:
- whether the code clears when you start a programme.
- If it clears:
- it was a temporary control state; watch whether it repeats.
- If it stays:
- move on to the lint filter.
- Evidence to keep:
- a photo of the display with the exact code (NC, NC1 or NC2).

Lint filter assembly
- Who:
- you, with the dryer unplugged.
- How:
- take out the lint filter, check that all its parts are there and push it fully back in.
- Result that matters:
- the filter complete and properly seated.
- If the code clears:
- a badly fitted filter was the cause.
- If the code stays:
- the filter fit is ruled out; if it is NC2, check the heat exchanger cover.
- Evidence to keep:
- a photo of the fitted filter.

- the cover properly closed.
- If the code clears:
- a badly fitted cover was the cause.
- If the code stays:
- it is time to call Samsung service.

What it means
In its tumble dryer code table, Samsung defines NC and NC1 as Check filter: a lint filter problem, with the instruction to check the lint filter assembly. NC2 is different: it points to the internal heat exchanger cover. As a first step, Samsung recommends unplugging the dryer for at least 30 seconds so the control can reset. If the code stays with the filter fitted, Samsung refers you to its service centre. The code alone does not prove the filter or its sensor is faulty.

Evidence: Samsung Tumble Dryer error codes - what do they mean?
- Heat exchanger cover (NC2)Possible
If the display shows NC2 rather than NC, Samsung points to the internal heat exchanger cover, not the lint filter. That assembly is what to check.

- Fault that stays with everything fittedPossible
The code stays with the filter and cover fitted and after the 30 second reset. Samsung then refers you to its service centre.
