Samsung Range Error Codes: Complete 2026 Guide (SE, C-d1, C-20, E-08 and All Fault Codes)

Universal Reset Procedure for Samsung Range Error Codes

Every Samsung range error code should go through the same two-step reset before any diagnostic work — this clears transient faults and confirms whether a physical component has actually failed:

1. Press Cancel or Off. This is the primary clear key on all Samsung ranges. It clears the displayed error and returns the panel to standby. If the code clears and does not return during the next cooking cycle, it was a transient electronic event — no hardware has failed.
2. Circuit breaker reset. If Cancel does not clear the code, or if the code reappears within a few minutes, turn the circuit breaker for the range to the OFF position for 60 seconds. This fully discharges the control board's capacitors and resets the door lock motor's position memory. Restore power and wait 2 minutes before using the range.

If the same error code reappears after a circuit breaker reset during normal use, a physical component has failed. A reset will not fix it — but it proves the fault is genuine and eliminates "ghost code" as a possibility, saving diagnostic time.

SE / 5E — Touchpad Stuck Key (Most Common Samsung Range Error Code)

SE (sometimes displayed as 5E — the display hardware renders the letter S and the number 5 identically on many Samsung panels) is by far the most frequently reported Samsung range error code. It means the control board has detected one or more touchpad keys registering as continuously pressed for more than a few seconds.

Why it happens on Samsung specifically: Samsung ranges use a glass or polycarbonate membrane touchpad with capacitive or resistive key contacts behind it. Steam, cooking grease, and condensation from daily use gradually infiltrate the membrane layer and create a low-resistance short across a key contact. Self-clean cycles are a particularly common trigger — the extreme heat (900°F / 482°C in the cavity, elevated temperatures at the control panel) can warp the membrane and permanently bridge a contact.

Diagnosing Touchpad vs. Control Board: The Ribbon Cable Test

Before ordering any part, confirm whether the fault is in the touchpad or the main control board:

1. Unplug the range or turn off the circuit breaker.
2. Remove the rear panel or control panel housing to access the touchpad ribbon cable connector on the main control board.
3. Disconnect the ribbon cable. Restore power.
4. If SE is gone — the touchpad is at fault. Order a replacement touchpad panel ($80–160 for most NE58 and NE63 models).
5. If SE is still displayed with the touchpad disconnected — the main control board has a shorted input circuit. The board needs replacement ($150–350).

In the field, the touchpad membrane is the culprit in approximately 80% of SE occurrences. The control board is only implicated when the ribbon cable test returns SE with the touchpad disconnected, or when SE appears on a brand-new replacement touchpad.

C-d0 / C-d1 / C-d2 — Door Lock Errors

Three closely related codes all point to the door lock mechanism — the motorized latch that secures the oven door for self-clean cycles:

• C-d0: The door lock is in an indeterminate state — neither confirmed locked nor confirmed unlocked. Also displayed when the range is placed in Demo/Showroom Mode (controls respond but oven does not heat). To exit demo mode, press and hold two designated buttons (varies by model — typically Clock + Self Clean) for 3 seconds.
• C-d1: The door lock motor attempted to lock but did not reach the locked position within the expected time. This is the most common of the three and almost always appears after a self-clean cycle or when one was interrupted early.
• C-d2: The door lock motor attempted to unlock after a self-clean cycle but the latch did not reach the fully unlocked position. Result: the door may be physically stuck in the locked position after self-clean completes.

C-d1 Recovery Steps After Self-Clean

C-d1 after self-clean is almost always recoverable without parts:

1. Do not force the door open. The oven cavity may still be extremely hot. Wait at least 90 minutes after self-clean completes before any intervention.
2. Turn off the circuit breaker for 60 seconds to reset the lock motor's position. Restore power. In many cases, the motor will complete its unlock sequence on the next power-on.
3. Inspect the door latch area with a flashlight for any charred food debris or carbon buildup around the latch slot in the door frame. A buildup of even 1–2mm can prevent full latch engagement. Clean with a non-metallic scrubber — avoid metallic tools near the lock mechanism.
4. Start a new self-clean cycle, then immediately cancel it. This forces the lock motor to re-run its sequence. On many Samsung models this is the fastest resolution for a C-d1 or C-d2 after a completed self-clean.
5. If C-d1 returns at the next self-clean attempt after all the above: the door lock motor assembly has worn and requires replacement.

Repair cost: Door lock motor assembly — $40–100 in parts depending on model (most NE58 and NE63 models use the same lock assembly). All-in with a technician: $180–280.

E-08 — Oven Not Reaching Temperature

E-08 means the oven failed to heat to the target temperature within the expected window — the control board commanded the heating system on, sensed the cavity temperature was not rising as expected, and shut down the cycle. It is the Samsung equivalent of LG's F9 and Whirlpool's F9 E0.

Electric ranges (NE58, NE63, NX58, NX63):

• Bake element failure (most common): Visually inspect the element on the floor of the oven cavity. A failed element almost always shows visible cracks, blistering, or a burn spot where the wire inside has arced. If the element looks intact, test with a multimeter: disconnect the range from power, remove the two mounting screws holding the element to the oven rear wall, and measure resistance at the element's wire connectors. A healthy Samsung bake element reads 15–35 ohms. An infinite resistance reading (OL) confirms failure. Replacement elements: $30–70 for most models. This is a beginner DIY — 2 screws, 2 push-on wire connectors, 15 minutes.
• Temperature sensor fault: If the bake element tests normal, the oven temperature sensor (a thin probe mounted at the top-rear interior wall) may be reading incorrectly. At room temperature (~70°F), a healthy Samsung oven sensor reads approximately 1,090 ohms. A significant deviation — or a reading of OL (open circuit) — confirms sensor failure. Sensor replacement: $20–50, same 2-screw procedure as the element.
• Bake element wiring: If both the element and sensor test correct, inspect the element wiring harness connectors at both ends (at the element and at the control board) for loose contacts, heat damage, or corrosion.

Gas ranges (NX60, NX58G gas models): E-08 on a gas range indicates the oven burner failed to reach temperature. The oven igniter may be drawing insufficient current — a Samsung gas oven igniter must draw approximately 3.2–3.8 amps to fully open the gas safety valve. An aging igniter can still glow visibly while drawing only 2.0–2.8 amps — not enough to open the valve. If the burner takes more than 90 seconds to light, replace the igniter before considering the gas valve ($40–80 for the igniter; $150–280 all-in with labor).

E-08 on broil only: If E-08 appears exclusively when using the Broil setting, while Bake works normally, the broil element (top of cavity) has failed separately. Test it with the same 15–35 ohm resistance target as the bake element.

C-20 / C-21 — Overtemperature Codes (Safety-Critical)

C-20 and C-21 are Samsung's overtemperature alarm codes. Both require immediate attention — they indicate the oven cavity has reached a temperature above its safe operating threshold.

C-20 — Oven temperature rising too rapidly: The oven temperature is climbing faster than the control board expects for the selected setting. Most commonly caused by a temporarily blocked vent or an oven sensor reading slightly low (causing the board to command more heat than needed). A single C-20 occurrence often resolves after a breaker reset and ensuring the oven vent slots (typically at the rear burner surface) are clear. Repeated C-20 codes warrant professional inspection of the temperature sensor and relay board.

C-21 — Safety-critical overtemperature: The oven has reached a temperature significantly above the safe threshold and the control board cannot bring it under control. Press Cancel/Off immediately. Do not open the oven door while the cavity is overheating. If the code does not clear or the oven continues to feel abnormally hot, shut off the circuit breaker. Do not use the range again until a technician has inspected the temperature sensor and the relay board. C-21 that recurs on a sensor that tests correctly almost always indicates a relay contact welded shut on the main control board — a situation that will not self-resolve and is a fire hazard.

Root causes of C-20 / C-21 in order of frequency:

1. Failed temperature sensor reading low (causing the board to command excess heat)
2. Relay contact welded closed on the control board, keeping the bake or broil element permanently energized
3. Main control board failure (rare, typically after one of the above has already been ruled out)

Repair cost for relay board replacement: $180–350 for parts; $350–550 all-in with a technician.

E-0A / E-0b / E-24 — Relay and Control Board Codes

These three codes indicate faults in the control board's relay section — the components that switch the bake element, broil element, and other high-current loads on and off based on the board's commands:

• E-0A: Relay contact fault — a relay on the control board has failed in the open position (element cannot be energized) or the board has lost confidence in the relay's state. First response: 60-second breaker reset. If E-0A returns during the next cooking cycle, the control board requires replacement.
• E-0b: Broil element relay fault. Specifically flags the broil circuit relay. Same diagnostic path as E-0A. Before concluding the board is failed, verify the broil element itself is not open-circuit (test resistance: 10–25 ohms healthy; OL = failed element). A failed broil element that draws no current can sometimes trigger E-0b as a secondary effect.
• E-24: Relay contact or oven temperature rising anomaly — related to the control board's detection that the oven temperature is not responding correctly to relay commands. May co-occur with C-20 on some Samsung models. A 60-second breaker reset is the first step. If E-24 returns, inspect the temperature sensor before replacing the board.

All three codes: If a breaker reset does not resolve them, do not attempt to use the range until the control board has been inspected. A relay fault that allows an element to remain energized without a command is a fire hazard analogous to C-21.

C-d3 / E-0E — Temperature Sensor Codes

Where C-d1 and C-d2 deal with the mechanical door lock, C-d3 on some Samsung models indicates a door sensor or position switch fault — the board cannot confirm the door's physical position. This is distinct from a door lock fault. Check for any debris or damage to the door position switch (a small mechanical switch visible inside the door frame) before ordering a lock assembly.

E-0E signals an oven temperature sensor (NTC thermistor) that is reading out of the expected range — either an open circuit (broken wire or failed element) or a short circuit (near-zero ohm reading). The diagnostic is identical to the sensor test described in the E-08 section above: disconnect the range from power, remove the sensor probe (two screws, rear interior wall), and test resistance at the connector. Target at 70°F room temperature: approximately 1,090 ohms. OL (open) or near-0 ohm (short) both confirm sensor failure. Replacement: $20–50, 15-minute swap.

nF / nC — Gas-Specific Codes

These codes appear only on Samsung gas ranges (NX60 series and NX58 gas models) and relate to the gas ignition system:

• nF (No Flame): The oven burner igniter attempted to light but the control board did not detect a flame within the expected time. The most common cause is a failing igniter — see the E-08 gas diagnosis above. Also check that the gas supply valve to the range is fully open. If nF appears on surface burners (not just the oven), inspect the surface burner igniters and the burner caps for alignment and clogged ports.
• nC (No Communication): The main control board has lost communication with the gas valve control circuit. This is less common and typically indicates a wiring harness failure or a failed gas valve solenoid board. A 60-second breaker reset is the first step. If nC returns, have a licensed technician inspect the gas valve wiring — any work near the gas valve system should be performed by a qualified appliance technician or gas service professional.

bE — Button Error

bE is related to SE but indicates a slightly different failure mode. Where SE is a key registering as continuously pressed, bE signals that the control board has received an invalid or unexpected button signal — either a button combination that isn't a valid command, or a button that fired at a time when input is not expected. bE is more commonly associated with button pad circuit board faults than with moisture-induced shorts.

A 60-second breaker reset resolves most bE occurrences. If bE returns regularly, particularly during or immediately after cooking, the control panel button board may have a failing solder joint or damaged trace. Repair typically requires touchpad or control board replacement ($80–350 depending on model and which component is at fault).

2024 Samsung Electric Range Recall: What Error Code Users Need to Know

In August 2024, Samsung and the U.S. Consumer Product Safety Commission (CPSC) issued a recall of approximately 1,120,905 Samsung slide-in electric ranges due to a fire hazard. The recall is not triggered by a fault code — it is a design issue with the front-mounted control knobs that can be activated accidentally by a person or pet brushing against them, turning on a burner without the owner's awareness.

Affected models include NE58K9430SS, NE58N9430SG, NE58R9431SG, NE58R9431SS, NE58R9431ST, NE58F9500SS, NE58K9500SG, NE58F9710WS, NE58K9850WS, NE58K9852WG, NE63T8111SG, NE63T8111SS, NE63T8311SG, NE63T8311SS, NE63BG8315SS, NE63CB831512, NE63BB851112, NE63T8511SG, NE63T8511SS, NE63A8711QN, NE63BB871112, NE63T8711SG, NE63T8711SS, NE63T8751SG, NE63T8751SS, and others manufactured May 2013 through August 2024.

Remedy: Free knob lock kits are available from Samsung. Contact Samsung at 1-833-775-0120 (M–F, 9am–8pm ET) or visit samsung.com/us/support/range-knob-kit. If your range is also displaying an error code, treat the recall and the error code as separate issues — the recall remedy does not resolve hardware fault codes.

Use ApplianceIQ's recall check to verify recall status and any open safety actions on your specific model and serial number in seconds.

All-in costs are 2026 US estimates including parts and labor in a typical market. Actual costs vary by region, service provider, and model. Safety codes (C-21, E-0A when persistent, nC) require professional inspection regardless of cost.

Samsung Range Error Codes: DIY vs. Call a Tech

Always run the two-step reset first — Cancel/Off, then 60-second breaker off — for every code before doing anything else. SE, C-d1, C-d0, and E-24 are frequently transient and may not return after a clean power cycle.

Safe to diagnose and repair yourself:

• SE / 5E (touchpad stuck key): Clean the panel with a dry cloth. Inspect for sticky residue. Do the ribbon cable test to confirm touchpad vs. board. Touchpad membrane replacement is a moderate DIY on most NE58/NE63 models — the control panel housing typically releases with a few screws or clips.
• E-0E (temperature sensor): Sensor replacement is a 2-screw, 2-connector swap with the range unplugged. Beginner-level repair on all Samsung ranges. Always confirm the range is completely unplugged and has been off for 10+ minutes before touching any internal wiring.
• E-08 on electric (bake/broil element): Visual check for damage, then multimeter test. Bake element swap is a beginner DIY — unplug, 2 screws, 2 push-on connectors. Verify with a multimeter before ordering parts — a bake element that looks intact can still be open-circuit.
• C-d0 / C-d1 (door lock) — after the recovery steps above: Door lock motor replacement is a moderate DIY on most freestanding models. Access typically requires removing the rear control panel. Confirm your model's specific disassembly path before ordering parts.
• nF (no flame) on gas: Checking gas supply and inspecting igniter alignment is safe. Replacing the oven igniter is moderate-difficulty DIY — requires shutting off the gas supply to the range, accessing the oven bottom, and a leak test after reassembly. If you are not comfortable with gas leak testing, use a licensed technician.

Call a licensed technician:

• C-21 (overtemperature): Do not attempt to use the range if C-21 returns after a breaker reset. Relay board inspection and replacement cannot safely be done without proper diagnostic equipment to confirm which relay is at fault.
• E-0A or E-0b that returns after a breaker reset: A relay contact fault that persists is a potential fire hazard. A technician needs to confirm whether the relay is stuck closed (element remains energized when off) or stuck open (element cannot be energized) before ordering any part.
• nC (gas valve communication) on gas models: Any fault involving the gas valve control circuit should be handled by a licensed appliance technician or gas service professional. This is a safety-critical system.

Repair vs. Replace: Applying the 50% Rule to Samsung Ranges

The appliance industry standard is the 50% rule: if the all-in repair cost exceeds 50% of a comparable replacement unit's current price, replacement is typically the better financial decision. In 2026, comparable Samsung freestanding electric ranges run $900–$1,600; slide-in models run $1,400–$2,400; gas models run $1,000–$1,800. The 50% threshold lands at $450–$1,200 depending on the model tier.

The key variable in the repair-vs-replace decision is the range's actual manufacture date — not the purchase date, which can lag the manufacture date by 12–18 months if the unit sat in a warehouse or showroom. The manufacture date is encoded in Samsung's serial number: the 8th character is the year code and the 9th is the month code on 15-character serials. Use the Samsung serial number decoder guide to extract the exact manufacture date, or look it up instantly at /product/serial-decoder. Then run the repair-vs-replace math with the correct manufacture date before committing to an expensive repair.
