17 error codes

CodeMeaning
C-20C-20 means the control board is reading near-zero resistance from the oven temperature sensor, which is physically impossible under normal conditions. Basically the sensor circuit shorted, so the board can't trust any temperature data and locks the oven down completely. It's a safety lockout, not a glitch.
highintermediate
C-21Samsung C-21 means the NTC temperature probe resistance is outside the acceptable range, either reading too high (open circuit) or too low (basically a short). The control board can't establish a valid temperature reading and shuts the oven down as a safety measure.
highbeginner
C-24Samsung oven C-24 indicates a fault in the lower oven temperature sensor circuit on dual-oven models equipped with the FlexDuo divider system. C-24 is specific to Samsung FlexDuo ranges (NE59M6850SS, NE63T8911SS) - it appears only when the FlexDuo divider panel is installed, creating a separate lower oven cavity with its own dedicated NTC sensor.
moderateintermediate
C-A2Samsung's C-A2 fires when the control board can't detect the convection fan spinning at the right speed, or at all. That fan's the one inside the oven cavity that circulates hot air for even baking. No fan movement detected means the board shuts things down before the heating element cooks the electronics.
moderatebeginner
C-F2Samsung oven C-F2 means the oven temperature exceeded the 610 degrees F safety threshold, triggering an automatic shutdown. Unlike GE F2 which almost always points to a stuck relay on the control board, Samsung C-F2 has an additional possible cause specific to Samsung's design: a thermal cutoff fuse placed in series with the bake element circuit that blows at high temperatures and generates the same C-F2 code even when the board is working correctly.
highintermediate
COOKTOP-SCRATCHSurface abrasions or deep gouges on the glass ceramic cooktop caused by abrasive cleaning, sliding heavy cookware, or metal transfer from pan bottoms.
lowbeginner
DOOR-STUCKDuring self-clean, Samsung's control board energizes a latch motor to drive a hook bolt into the door frame. The board won't reverse that motor until it sees the cavity temperature drop below around 300°F from the thermal sensor. If that signal never comes, the door stays locked.
moderateintermediate
E-08E-08 means the control board got a temperature reading that's outside safe limits, or it lost communication with the RTD sensor entirely. The board panics and shuts everything down. Could be the sensor sending bad data, or the board misreading good data from a corroded connection.
highintermediate
E-24The E-24 error code signifies a communication failure between the oven's main control board and the sub-PCB, which is typically the display or touch interface board.
highintermediate
E27The control board is looking for a specific resistance value from the thermistor probe inside the oven cavity. When it sees an open circuit, a short, or a resistance value that's way outside the normal range, it decides the temperature sensor circuit has failed and throws E27 to prevent a runaway heating situation.
highintermediate
HUBThese C-prefix codes fire when the oven's temperature sensing circuit detects something's off. C-21 and C-24 are sensor faults, C-F2 means temperature runaway or a tripped safety fuse, and C-A2 is the convection fan. Samsung's NTC thermistor reads 10K ohms at room temp and resistance drops as heat rises. That's completely opposite from the RTD probes GE and Frigidaire use.
highintermediate
IGNITER-TROUBLESHOOTWhen you're troubleshooting this, you're basically checking if the igniter can draw enough current to heat the bi-metal strip inside the gas valve to the point where it snaps open. It needs to hit around 3.2 amps minimum. Below that, the valve stays shut and no gas gets through, period.
highintermediate
NOT-HEATINGThe oven's heating system has failed to produce or maintain temperature. Either the bake element has burned through, the gas igniter can't draw enough current to open the gas valve, or a safety component like the thermal fuse has tripped permanently to protect the appliance from damage.
moderateintermediate
RESET-PROCEDURESamsung ovens don't have a dedicated reset button. A reset means cutting all power so the control board loses its temporary memory and reboots fresh. You do that through the circuit breaker, or for minor glitches, through a keypad combination that interrupts whatever software loop it's stuck in.
lowbeginner
SESE means a key on your touchpad is sending a continuous 'pressed' signal to the control board. Could be a physical short in the membrane layers, moisture bridging the contacts, or heat causing the layers to mash together. The board sees a button held down indefinitely and throws the fault.
moderateintermediate
SMOKINGGrease, food debris, or factory coating on the heating elements or oven interior is combusting at high temperature. Less commonly, a bake or broil element is arcing and burning through its own metal coating as it starts to fail electrically.
moderateintermediate
WONT-STARTSamsung's control system lost a key input it needs to run a heating cycle. Could be no power reaching the board, a blown thermal fuse cutting the circuit, a locked control panel, or a relay board that's stopped passing commands to the elements.
