Samsung oven C-24: Oven temperature rises too quickly

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

Oven temperature rises too quickly.

C-24 means temperature is rising faster than expected. A covered rear cooktop vent is a documented cause to check.

First safe check

Look for cookware or another object covering the rear oven vent.
