Samsung cooktops share the MICOM control-code family used on Samsung ranges and ovens. C-F0 and C-F1 flag a communication fault between the touch control and the main board. C-20 through C-22 flag a temperature-sensor fault, most relevant on induction models that monitor pan and coil temperature, with C-10 as the sensor self-test. C-d0 flags a stuck or shorted key. An underlined “u” on an induction zone means the cooktop does not detect an induction-compatible pan on that burner — it is a detection message, not a hardware failure, and usually clears with a magnetic-base pan of the right size and position. -SE- flags a shorted touch key, often from spills or moisture pooled on the glass. Wipe the control area dry, power-cycle at the breaker, and try a different pan for the “u” message; a temperature, key, or communication code that returns points at the touch panel, a sensor, or the induction coil driver, and needs a hands-on check to isolate. See the error codes library, then book cooktop repair.
