Error codeu (underlined u)
ApplianceRange
Quick answer
The underlined u code is a Pan Detection Error on Samsung induction cooktops and ranges. Cookware size, material or placement is the issue.
Model compatibility: Samsung reuses codes across series and model years, so u (underlined u) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Pan Detection Error (induction): cookware unsuitable by size, material or placement; element turns off after 1 minute.
The underlined u symbol on the display depicts a pot bottom over a surface. This Pan Detection Error is limited to Samsung induction cooktops and ranges.
What triggers it
Unsuitable cookware, whether by size, material or position on the element, makes the code appear. The pan will not heat, and without a fix the element turns off after 1 minute.
What to check
Check how big the pan is, what it is made of and where it sits on the element.
Reach Samsung range service in Los Angeles by calling (310) 896-4231. The oven and range repair page has the range details; when you call, bring the code, the model number and whatever you already tried.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
