Samsung Range Underlined u error code

Difficulty: Easy · Cost: $0 · Duration: 1m

The underlined u symbol appears on Samsung induction cooktops and ranges and indicates a Pan Detection Error. It means the cookware placed on the induction element is unsuitable due to its size, material, or placement. Induction cooktops require magnetic cookware — stainless steel, cast iron, or induction-ready pans work correctly. If the issue is not corrected the element will turn off automatically after 1 minute.

Common causes

  • Cookware material is not induction-compatible — non-magnetic pans such as aluminium, copper, or glass will not work
  • Pan is too small for the induction element it is placed on
  • Pan is not centered properly on the element

How to fix it

  1. 1

    Check that the pan is made from a magnetic material — hold a magnet to the base of the pan to confirm it is induction-compatible

  2. 2

    Make sure the pan is large enough for the element and is centered on it

  3. 3

    Replace the cookware with an induction-compatible pan if it is not magnetic

  4. 4

    If the code appears with induction-compatible cookware that is correctly placed arrange professional service
