Samsung Oven & Range Error Codes List: Every Code Explained
Every Samsung oven & range error code we could verify against Samsung's own documentation — what it means, what usually causes it, and the first fix to try — in one table. Codes differ between model series, so treat your model's tech sheet as the final word.
How to read and retrieve error codes on Samsung oven & ranges
Samsung ranges have a diagnostic/service mode on many models (entered with a pad sequence from the service manual) that displays stored error history (the C and E code families) and allows sensor readings (including the oven temperature sensor's live resistance-derived reading) to be checked without disassembly.
The complete Samsung oven & range error code list
| Code | Meaning | Most likely cause | First fix |
|---|---|---|---|
| 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. | Wi-Fi setup was started | Complete the pairing in SmartThings, or press the Smart Control button again / power-cycle to exit setup mode. |
| Bad Line | 'Bad Line' on a Samsung oven display = power line/supply problem — the oven is detecting incorrect or unstable incoming power (not a cooking fault). | One leg of the 240V supply missing | Correct the supply: breaker, receptacle, or terminal-block fault — electrician work for anything beyond resetting a breaker. |
| C-20 | Oven sensor malfunction; oven sensor is open or shorted while operating (fold 'C20'). | Open or shorted oven temperature sensor. | Press OFF/CLEAR and restart; disconnect power 30 seconds if it persists, then service. |
| C-21 | Oven temperature sensor fault — the sensor circuit is reporting implausible values (C-2x family member). | Sensor failure/drift | Replace the sensor if out of spec; repair the connector/harness if the sensor meters good at its terminals. |
| C-22 | Sensor malfunction; sub PCB sensor is open or shorted on range manuals. | Open or shorted sub PCB sensor while oven operating. | Press OFF and restart; disconnect power 30 seconds if it persists, then service. |
| C-23 | Temperature probe sensor is shorted while the oven is operating. | Short in the temperature probe sensor. | Press OFF and restart; disconnect power 30 seconds if it persists, then service. |
| C-24 | Oven temperature sensor fault family — C-24 is associated with the oven sensor circuit reading out of range on the high side (sensor resistance abnormal). | Temperature sensor drift/failure | Replace the sensor if its reading is out of spec with a sound connector. |
| C-30 | Main PCB sensor is open or shorted while the oven is operating. | Open or shorted main PCB sensor. | Press OFF/CLEAR and restart; disconnect power 30 seconds if it persists, then service. |
| C-31 | PCB temperature rises abnormally high (fold 'C31' is this code). | Control board (PCB) overheating. | Call for service; Samsung manuals list no user reset for this code. |
| C-A2 | Cooling-fan / panel-cooling error on Samsung ovens (C-A family covers the control-cooling system). | Cooling fan motor failure | Clean or replace the cooling fan (access via the rear/top panels, power off). |
| C-F0 | No signal / communication fault — the control is not receiving the expected signal (Samsung C-F family: key input / board communication). | Panel ribbon/connector fault | Reseat/inspect the panel connections (power off). |
| C-F1 | Error occurring only during EEPROM read/write operation. | EEPROM read/write failure on the control board. | Turn oven off and restart; power off 30 seconds or more and reconnect if it persists. |
| C-F2 | Communication error between the main control board and the touch panel (C-F family on Samsung ovens). | Loose or corroded panel connector/ribbon | Reseat and inspect the panel ribbon/connectors (power off). |
| C-d0 | Stuck/shorted key signal on Samsung ovens without a keypad membrane fault being isolated (C-d0 = a button seen as continuously pressed). | Moisture or cleaner in the panel | Dry-out first; reseat the panel ribbon if the fault persists. |
| C-d1 | Door lock/door switch fault on Samsung ovens — the control cannot confirm the door lock state (self-clean lock circuit). | Lock motor failure | Clear obstructions; straighten or replace a bent latch/strike. |
| E08 | Low-frequency/rarely documented Samsung oven code — not part of Samsung's core published oven code list; treat as a platform-specific fault and diagnose by symptom with the model's tech sheet. | A platform-specific sensor or control fault | Diagnose from the model's own documentation once the code's local meaning is known. |
| E-0A | Oven heating over (overheating) on older range models (fold '0A' is this code). | Oven heating exceeded its limit. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-0E | Door locking error on older range models (fold '0E' is this code). | Door lock mechanism fault. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-2E | Temp probe error on older slide-in range models. | Fault in the temperature probe. | Press OVEN OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-21 | Oven sensor opened on older slide-in range models. | Open circuit in the oven temperature sensor. | Press OVEN OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-22 | Oven sensor shorted on older slide-in range models. | Short circuit in the oven temperature sensor. | Press OVEN OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-24 | Oven heating over (overheating) on older slide-in range models (fold 'E24'). | Oven temperature rose above its limit. | Press OVEN OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-27 | Oven sensor opened on older range models (fold 'E27'). | Open circuit in the oven temperature sensor. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-28 | Oven sensor shorted on older range models (fold 'E28'). | Short circuit in the oven temperature sensor. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-54 | Communication error between oven main control and HYB30M on older models. | Interrupted communication between main control and cooktop module. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-55 | Communication error between oven main control and Touch PCB on older models. | Interrupted communication between main control and touch board. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-56 | Communication error reporting a cooktop error on older models. | Cooktop error communicated to the oven control. | Press CLEAR/OFF and restart; disconnect power 30 seconds if it persists, then service. |
| E-83 | Communication error on older slide-in range models (fold 'E83' is this code). | Communication fault between oven controls. | Press OVEN OFF and restart; disconnect power 30 seconds if it persists, then service. |
| OE | Not a standard Samsung oven fault code — OE is a washer/dishwasher-family code (drain/overflow); on an oven it most likely indicates a mis-read display or a model-specific rendering that needs the model's own code table. | Display mis-read | Diagnose the actual oven symptom with the correct code list: no-heat faults, sensor faults and panel faults each have their own Samsung oven codes and pages. |
| Pr E | Oven is preheating; display clears when set temperature is reached. | Normal preheat in progress, not a fault. | Keep door closed and wait until display disappears at set temperature. |
| S-01 | Safety shutoff; oven ran at a set temperature for an extended time. | Timed shutoff: 16 hours under 105C, 8 hours 105-240C, 4 hours above. | Not a failure; turn oven off, remove food, then use normally. |
| SE | Keypad short / touch panel error — a shorted key or faulty touch membrane on the oven control. | Moisture/cleaner ingress | Dry-out period first (above) — free and surprisingly often permanent when moisture was the cause. |
| dC | Divider check needed, displayed as -dC-; divider inserted or removed while oven operating (fold 'DC'). | Divider removed in Dual Cook mode or inserted in Single Cook mode. | Seat divider properly and restart; power off 30 seconds or more if it persists. |
| dE | Divider error, displayed as -dE- on older models; divider check needed on newer models. | Divider removed in Dual Cook mode or inserted in Single Cook mode. | Seat divider properly and restart; power off 30 seconds or more if it persists. |
| tE | Communication error (Touch), displayed as -tE- on older models (fold 'TE'). | Touch control communication fault. | Press OVEN OFF and restart; disconnect power 30 seconds if it persists, then service. |
How to reset / clear error codes on Samsung oven & ranges
Samsung range codes clear with a power reset: trip the breaker for about 5 minutes (ranges are usually hard-wired or on a 240V outlet behind the unit — the breaker is the safe disconnect), restore power and test a bake cycle. Keypad and sensor codes that return at power-up are active faults the board detects in its start-up self-check.
How to diagnose any Samsung oven & range code
Work the problem in this order: (1) record the code exactly — ranges often show the code only briefly or store it, so write it down before resetting the breaker; (2) note the context: did it appear during preheat, mid-bake, broil, or during/after a self-clean cycle — oven codes split into temperature-sensing, latch/lock, and control families, and self-clean heat is the stress that exposes most of them; (3) let the oven cool fully before judging a latch or sensor fault, because several codes are thermal states, not failures, until the temperature falls; (4) run the external checks: breaker fully reset (both poles on a double breaker), the oven sensor probe visibly intact and not touching the cavity wall, the door closing and latching evenly; (5) test the temperature sensor before the control board — sensors drift and fail far more often than boards, and an oven that consistently runs hot or cold with no code is describing the same component. Do not run self-clean again on an oven that coded during one until the cause is found.
The most searched Samsung oven & range codes, in detail
E08 — Low-frequency/rarely documented Samsung oven code
E08 does not appear in Samsung's standard published oven fault lists (which run through the F, C-, E- families documented for each model). Owners occasionally report E08-style codes from specific regional or older platforms, but Samsung publishes no universal definition, and inventing one would send you after the wrong part. The reliable approach: capture the exact display, note what the oven was doing when it appeared, and use the model's tech sheet (tucked inside the oven's rear panel or toe-kick area) or Samsung service for that model.
Most likely cause: A platform-specific sensor or control fault — On the models that use it, E08 belongs to that model's own code table — which only the tech sheet defines.
First check: Photograph the exact display and note the cooking mode in use when it appeared.
If it keeps coming back: If E08 returns with a pattern (only in self-clean, only at high temperature), that pattern plus the tech sheet is what a technician will use — note it.
OE — Not a standard Samsung oven fault code
Samsung's oven fault system uses F-codes, C-codes (C-21, C-F2, C-A2, C-d0/d1) and SE for the keypad. OE is not among the published Samsung oven codes — it belongs to Samsung laundry/dishwasher families (drain on dishwashers, overflow on washers). If an oven display seems to show OE, the productive steps are: confirm the characters (displays are easy to misread), confirm the appliance family the code list belongs to, and then diagnose the oven's actual symptom (no heat, panel fault, door fault) with the oven's own code table.
Most likely cause: Display mis-read — Partial segments can render other characters as 'OE'.
First check: Photograph the display and re-read the characters carefully.
If it keeps coming back: If the display repeatedly shows unclear characters, the panel/board itself may be failing segment drivers — a technician can confirm with the panel test in service mode.
SE — Keypad short / touch panel error
On Samsung ovens and ranges SE is the well-known 'shorted keypad' code: the control detects a key that appears permanently pressed — a short in the touch membrane, moisture or cleaner ingress behind the panel, or a failing control board input. The oven usually beeps, may accept phantom inputs, and locks out cooking for safety. It is the oven equivalent of a stuck button.
Most likely cause: Moisture/cleaner ingress — Steam from kettles/pans and spray cleaners creep into the membrane edges — SE often follows a big steam cooking day or a panel wipe-down.
First check: Kill power and let the panel dry: leave the breaker off for 24 hours in stubborn moisture cases — many SE faults clear permanently once dry.
If it keeps coming back: SE that returns after dry-outs, increasingly quickly, is a dying membrane: the short is becoming permanent. Replace the panel rather than living on resets.
AP — Access Point mode
AP on a Samsung oven display means the appliance has entered Wi-Fi Access Point mode for smart setup: it is broadcasting its temporary setup network so the SmartThings app can find and register it. It appears after pressing the Smart Control / Wi-Fi setup button (or during first-time setup) and is a normal state, not a fault. The oven's cooking functions are unaffected; AP simply times out or completes when pairing finishes.
Most likely cause: Wi-Fi setup was started — Someone pressed the Smart Control/setup control, or the oven is new and awaiting registration.
First check: If you were setting up SmartThings: continue in the app — select the appliance network if asked and finish registration.
If it keeps coming back: AP repeatedly appearing on its own points to a panel button issue rather than Wi-Fi — treat it as a panel problem only if it recurs uninvited.
Bad Line — 'Bad Line' on a Samsung oven display = power line/supply problem
Some Samsung ranges display the words 'Bad Line' (owners usually meet it right after installation or a panel/electrical change) when the incoming supply isn't what the oven requires — a missing leg of the 240V supply, a miswired outlet, a tripped half-breaker, or severe voltage sag. The oven refuses to operate its heating elements on a bad supply. Note: some harvest data mistitles this as a GE code — 'Bad Line' wording is characteristic of Samsung range displays; GE uses letter/number codes (F-series) for its faults.
Most likely cause: One leg of the 240V supply missing — A half-tripped double breaker, a failed breaker pole, or a burnt outlet contact — the oven gets 120V only and can't heat.
First check: Check the breaker: a double-pole breaker with one side tripped looks 'on' at a glance — switch it fully off, then on.
If it keeps coming back: Bad Line that comes and goes with heavy loads (AC, dryer running) suggests a deteriorating connection heating up under load — electrician promptly; that's a fire-risk pattern.
C-21 — Oven temperature sensor fault
C-21 sits in Samsung's oven-sensor family (C-20 short-side, C-24 high/open-side on Samsung's published convention); the family as a whole means the control cannot trust the temperature sensor. Symptoms are an oven that won't heat, heats erratically, or faults out mid-cook. Sensor, connector and harness — in that order — are the diagnosis.
Most likely cause: Sensor failure/drift — Heat-aged sensors leave their resistance window.
First check: Meter the sensor: ~1,080Ω at room temperature is healthy; far-off, open or shorted is not.
If it keeps coming back: Recurs with a proven sensor = board input fault.
Less common and model-specific codes
Search data shows owners also meet these codes on Samsung oven & ranges: 0A, 0E, E03, F0, F11, F2, F9, OA. They are not part of the core code list Samsung publishes for most models — several are series-specific, abbreviated display readings, or codes carried over from a sister platform — so we do not publish meanings for them rather than guess. Treat them by symptom: note what the machine was doing when the code appeared (filling, draining, heating, spinning), run one full power cycle (5 minutes off), and if the code returns, match the symptom to the closest documented family in the table above and check the tech sheet stored inside your machine for the model-specific definition.
