Most searched Samsung oven & range codes

Code	Meaning
AP	Access Point mode — not an error. AP means the oven's Wi-Fi is in pairing/setup mode, waiting to be connected to the SmartThings app.
Bad Line	Power cord installed improperly — Samsung's range manuals define the display 'bAd LinE' in one line: the message appears if the power cord is installed improperly (if the power connection is plugged in improperly), and it disappears when the power connection is reconnected properly. On Samsung ranges with an LCD display the same condition reads 'Wire installation fail'. It is an installation message about the range's own power connection, not a cooking, element or sensor fault.
C-21	The oven is overheating — Samsung's manuals define C-21 as the internal temperature rising abnormally high. Samsung's support site files C-21 with its sensor malfunctions (C-20/C-21/C-22), because the temperature sensor is the control's only witness to the heat. [Corrected 2026-10-28, verification pass: Samsung range manuals + samsung.com support + Samsung service manuals.]
C-24	Oven vent blocked — in Samsung's gas-range manuals, C-24 means the oven vent or cover air path is obstructed, so exhaust heat cannot escape properly. It is a heat-path report, not a sensor fault. [Corrected 2026-10-28, verification pass: Samsung manuals NX60A6711SS/AA + NX60A6311SS.]
C-A2	Cooling-system error on Samsung ovens — the definition is model-dependent (corrected 2026-10-28 against Samsung manuals): on Samsung wall ovens C-A2 means the cooling motor is operating abnormally; on Samsung ranges such as the NE63 series it means the sub PCB temperature has risen abnormally high.
C-F0	Communication interrupted between the main PCB and the sub PCB — Samsung's definition ('no communication between the main PCB and sub PCB'). The touch-panel link is a different code, C-F2. [Corrected 2026-10-28, verification pass: samsung.com support + Samsung service manuals DOB30 / NSE6D.]
C-F2	Communication error between the main control board and the touch panel (C-F family on Samsung ovens).
C-d0	Button problem — a short in the control key: Samsung range manuals define C-d0 as 'this code occurs if the Control key is short for 1 minute' (NE59-series) and 'there is a short in the control key' (NE63-series); Samsung support calls it a button problem that displays when a button is pressed and held for a period of time. (Corrected 2026-10-28 against the NE59K3310 and NE63A6511 range manuals, the NV51 wall-oven manual and Samsung's oven information-code page: the earlier entry's 24-hour dry-out procedure, ribbon-reseat step and membrane-replacement narrative appear in no Samsung source and have been removed — Samsung's remedy is the OFF/CLEAR sequence below.)
C-d1	Door lock/door switch fault on Samsung ovens — the control cannot confirm the door lock state (self-clean lock circuit).
E08	Oven heating error — Samsung's electric range manuals list E-08 in their function-code tables with the cause 'Oven heating error': the oven is not heating as it should when it is run. The same table gives the sensor faults their own codes (E-27 oven sensor opened, E-28 oven sensor shorted), the overheating fault its own code (E-0A oven heating over) and the door-lock fault its own code (E-0E door locking error) — E-08 is the heating failure itself, and Samsung's remedy for the table is CLEAR/OFF and restart, then disconnect all power for at least 30 seconds if the problem persists, then call for service.
OE	Not a Samsung oven code as printed — but the reading these searches are about, 'E OE', is Samsung's E-0E (E, zero, E): Door locking error. Samsung's range manuals list E-0E in their function-code tables with the cause 'Door locking error', alongside E-08 (oven heating error) and E-0A (oven heating over). A bare OE — letter O, letter E — appears in no Samsung oven list checked; OE/oE spellings belong to Samsung's dishwasher family, where Samsung US defines them as the over-level water error. On an oven display, the middle character is the whole diagnosis: 0 is a door-lock code, O is a mis-read.
SE	Keypad short / touch panel error — a shorted key or faulty touch membrane on the oven control.
