What Does Error U Mean?
The Samsung cooktop U error indicates a pan detection issue where the induction cooktop fails to recognize compatible cookware on the selected zone. This may result in the underlined 'U' appearing, and the affected zone will not heat. Common causes include using non-magnetic cookware or improper placement. To resolve, ensure the cookware is flat and magnetic, and centered on the cooking zone.
Common Symptoms:
- Underlined U appears when using a cooktop zone
- Affected zone does not heat
- Other error codes may not accompany this without pan detection
Possible Causes
- Cookware is not induction-compatible or not magnetic (high)
- Cookware improperly positioned or mismatched size (medium)
How to Fix Error U
DIY Fix Check cookware and placement
- Ensure you are using cookware with a **flat, magnetic base** suitable for induction cooking.
- Verify the pot/pan is placed **centrally on the active cooking zone**.
- Test cookware with a magnet — it should stick to the base.
- Use cookware whose diameter matches the size of the induction zone.
DIY Fix Power reset of cooktop
- Turn off the cooktop using the Power button.
- If the error persists, turn off power at the breaker or unplug for about **30–60 seconds**.
- Restore power and retry with proper cookware.
- Observe if the U code still displays.
Technician Only Inspect sensor and control circuits
- If U persists with correct cookware, inspect the **pan detection sensor circuitry** underneath the cooktop.
- Check wiring harnesses for the affected zone for loose or damaged connections.
- Test induction control board functionality with appropriate diagnostic tools.
- Replace faulty control board or sensor assembly as needed.
Parts needed: Induction cooktop pan detection sensor, Induction control board/PCB, Wiring harnesses
- If error persists after correct cookware use and power reset
- If multiple zones show U or other errors concurrently
- If there is physical damage or moisture under the cooktop surface
