Samsung Oven Error Codes: Complete List with Fixes

Samsung ovens and ranges — including the Flex Duo double-oven, Slide-in ranges with Wi-Fi, and the Bespoke line — deliver precise cooking through multiple temperature sensors, convection fans, and smart controls. When something goes wrong, the control panel displays an error code. This guide covers every Samsung oven and range error code with detailed causes, professional diagnostic tips, and step-by-step repair instructions.

How Samsung Oven Error Codes Work

Samsung ovens monitor the cavity temperature through RTD (Resistance Temperature Detector) probes, track door lock position during self-clean cycles, and watch for communication integrity between the display board and the relay board. Error codes appear as alphanumeric sequences on the front display — some use the "E-XX" format (E-08, E-27), while others use letter codes (SE, tE, C-10).

Important: Many Samsung oven errors trigger a safety lockout where the oven refuses to heat until the code is cleared. This is by design — operating without temperature feedback or with a stuck relay creates a fire hazard.

To reset most Samsung oven error codes:

1. Turn off the oven at the circuit breaker (not just the oven controls) for 5 minutes.
2. Restore power and test with a low-temperature bake cycle (250 degrees F).
3. If the code returns, the underlying component needs repair.
4. Some codes (like SE) clear on their own once the oven cools completely.

SE — Key Panel / Stuck Key Error

The control board detects a continuously pressed button or a short circuit on the touchpad membrane.

Common causes:

• Moisture from cooking steam on the touchpad surface (the most common trigger)
• Grease buildup on the glass panel affecting the capacitive touch layer
• Touchpad membrane delamination from self-clean cycle heat (900 degrees F+)
• Control board fault (Samsung DG92-01003D) if touchpad is not the issue

How to fix:

1. Turn off the oven at the breaker and wait 5 minutes. Moisture from cooking steam evaporates, clearing many SE codes.
2. Clean the touchpad surface with a dry microfiber cloth. For grease, spray a mild glass cleaner on the cloth (never directly on the panel).
3. If SE appeared during or right after self-clean, wait until the oven is fully cool — radiant heat from the 900 degree F cavity migrates to the panel and warps the membrane temporarily.
4. To diagnose: disconnect the touchpad ribbon cable from the control board. If the SE code clears with the touchpad disconnected, the touchpad assembly needs replacement (Samsung DG34-series, model-specific).

Part cost: Touchpad/membrane switch $40–$80 (model-specific). Control board (DG92-01003D) $100–$200. Professional repair $125–$300.

tE / tS — Temperature Sensor Error

The oven RTD temperature sensor probe is reading abnormally, is disconnected, or has an open/short circuit.

Common causes:

• RTD sensor failure (Samsung DG32-00002B) — common after repeated self-clean cycles
• Wiring insulation cracked or melted near the oven cavity where temperatures reach 900 degrees F+
• Sensor connector loose at the back of the range
• Sensor corroded from exposure to oven moisture and food spatter

How to fix:

1. Turn off the breaker. Open the oven and locate the temperature sensor probe — a thin metal rod extending from the back wall, usually in the upper-left or upper-right corner.
2. Remove the mounting screw (inside the oven) and unplug the connector at the back of the range.
3. Test the sensor resistance: at room temperature (77 degrees F) should read approximately 1,080–1,100 ohms. This is a standard 1,000-ohm platinum RTD at 32 degrees F. At 350 degrees F, it should read approximately 1,600 ohms.
4. If the reading is significantly below 1,000 ohms at room temperature, the sensor has an internal short. Above 1,200 ohms indicates corrosion resistance.
5. Inspect the wiring from the back of the range to the control board. The wires pass through a high-heat zone and insulation can crack, especially after self-clean cycles.

Part cost: RTD temperature sensor (DG32-00002B) $15–$30. Sensor wiring harness $20–$40 (model-specific). Professional repair $100–$250.

E-27 — Temperature Sensor Open/Short Circuit

A more specific version of the tE code indicating an explicitly open or shorted circuit in the temperature sensor wiring.

Common causes:

• Sensor wire broken inside insulation (reads OL/open on multimeter at board connector)
• Sensor shorted to the oven frame (reads near zero ohms)
• Wire insulation turned brittle and brown from self-clean heat exposure
• Sensor connector disconnected after oven was moved

How to fix:

1. Turn off the breaker. Measure resistance at the control board end of the sensor harness — should be approximately 1,080 ohms at room temperature.
2. If the board-end reading differs from the sensor-end reading, the wiring between them is damaged. Trace the wire path for breaks.
3. Look specifically where wires pass through the oven insulation — self-clean temperatures exceed the wire insulation rating at these transition points.
4. Replace the sensor wire harness if insulation is damaged. Replace the sensor (DG32-00002B) if the sensor itself tests out of range.

Part cost: Same as tE above. Professional repair $100–$275.

E-08 — Door Lock Malfunction

The oven door lock motor cannot engage or disengage, or the lock position switches are not confirming the expected state.

Common causes:

• Lock motor failure (Samsung DG94-00761C)
• Lock position switch contacts worn (Samsung DG34-00041A)
• Thermal expansion of the door preventing lock engagement during self-clean
• Lock slide rail dry — needs high-temperature grease

How to fix:

1. Turn off the breaker and wait 30 minutes for any residual self-clean heat to dissipate. The lock will not release while the oven is hot.
2. After cooling, restore power and try to unlock: press Cancel, then hold Broil for 3 seconds on some Samsung models.
3. If the door will not unlock, access the lock motor from the top of the range (remove screws securing the top panel). The lock assembly is behind the control panel area.
4. Test the lock motor by applying 120V directly — it should slide the lock bar. No movement means the motor has failed.
5. Apply high-temperature grease to the lock slide rail to prevent intermittent failures from thermal expansion friction.

Part cost: Door lock motor assembly (DG94-00761C) $40–$80. Door lock switch (DG34-00041A) $15–$30. Professional repair $150–$300.

E-OA / E-OB — Oven Overheating

The oven temperature has exceeded the safe threshold. E-OA indicates the upper/broil element; E-OB indicates the lower/bake element. This is a safety hazard — do not ignore.

Common causes:

• Control board relay welded closed (stuck on) — visible under magnification as fused contacts
• Temperature sensor reading artificially low, causing the board to overheat
• Bake element shorted to ground (Samsung DG47-00023A)
• Relay switching a failing element that draws excessive current, fusing the relay

How to fix:

1. Turn off the breaker immediately. Do not open the door if you suspect extreme heat — let the oven cool for 1–2 hours.
2. Test the temperature sensor (see tE section). A sensor reading too low causes the board to keep the element on.
3. If the sensor tests good, inspect the control board relay for burn marks or discoloration. A welded relay cannot be repaired — the board must be replaced.
4. Test the oven with a separate oven thermometer: set to 350 degrees F. If temperature climbs past 400 degrees F and keeps rising, the relay is confirmed welded.
5. Always test the element impedance when replacing the board — a failing element that draws excessive current will kill the new board too.

Part cost: Control board (DG92-01003D) $100–$200. Bake element (DG47-00023A) $30–$60. Temperature sensor (DG32-00002B) $15–$30. Professional repair $200–$450.

C-10 — Communication Error

The main relay board and the display/UI board cannot communicate over the internal serial bus.

Common causes:

• Power spike disrupting board-to-board communication (common on shared circuits)
• Communication cable damage or corrosion between boards
• Main relay board failure (Samsung DG92-01003D)
• UI/display board failure (Samsung DG92-01012A)
• Line noise from other appliances on the same circuit

How to fix:

1. Turn off the breaker for 5 minutes. Samsung dual-oven and slide-in models have multiple boards communicating over a serial bus — a power spike can disrupt communication.
2. Access the control boards by removing the back panel. Inspect the communication cable for damage, corrosion, or loose connectors.
3. Reseat all inter-board connections firmly.
4. If C-10 persists, replace the main relay board first (more common failure point). If it continues, the UI board or the harness between them is at fault.

Diagnostic tip: If the range shares a circuit with a microwave, dishwasher, or other motor-driven appliance, the motor start current causes line noise that can trigger C-10. A dedicated 40A or 50A circuit for the range eliminates interference.

Part cost: Main relay board (DG92-01003D) $100–$200. UI/display board (DG92-01012A) $80–$150. Communication cable $15–$30 (model-specific). Professional repair $225–$475.

E-54 — Convection Fan Error

The convection fan motor is not spinning or the control board cannot detect fan rotation. On Flex Duo models, E-54 may reference either the upper or lower convection fan.

Common causes:

• Convection fan motor failure — bearings seized or windings open
• Fan blade loose on the motor shaft (set screw backed out from vibration)
• Wiring harness damaged between fan motor and control board
• Control board not sending power to the fan motor circuit

How to fix:

1. Turn off the breaker. Remove the oven back panel inside the cavity (Phillips screws) to access the convection fan behind the rear wall.
2. Spin the fan blade by hand — it should rotate smoothly with no grinding. Grinding or stiffness means the motor bearings have failed.
3. Check that the fan blade is securely attached to the motor shaft. Tighten the set screw if loose.
4. Test the fan motor: disconnect leads and measure winding resistance (typically 15–30 ohms). Open reading confirms motor failure.

Part cost: Convection fan motor $40–$80 (model-specific). Professional repair $150–$300.

E-F2 — Oven Too Hot During Self-Clean

The oven temperature exceeded the maximum safe threshold during a self-clean cycle, triggering a safety shutoff.

Common causes:

• Door seal (gasket) deteriorated, allowing heat to escape and triggering uneven temperature readings
• Temperature sensor drift reading lower than actual (causing the oven to overshoot)
• Oven door not fully latched during self-clean, preventing proper heat containment
• Excessive food residue in the oven causing flare-ups during self-clean

How to fix:

1. Allow the oven to cool completely (2+ hours). The code will clear once the temperature drops.
2. Before running self-clean again, remove all racks and wipe up large food deposits. Heavy residue can ignite during the 900 degree F cycle.
3. Inspect the door seal/gasket around the oven frame — it should be soft, flexible, and make full contact when closed. A hardened or cracked gasket leaks heat.
4. Test the temperature sensor (see tE section) to ensure accurate readings.

Part cost: Door gasket $20–$40 (model-specific). Temperature sensor (DG32-00002B) $15–$30. Professional repair $100–$200.

Samsung Oven Diagnostic Mode

Samsung ovens offer diagnostic access for troubleshooting:

1. SmartThings App Diagnosis: For Wi-Fi-enabled models, open SmartThings, select your range/oven, and tap Device Care > Self Check. The app reads sensor data and error history.

2. Service Mode (non-smart models): Turn the oven off at the breaker. Restore power while holding the Bake and Broil buttons simultaneously for 3 seconds. The display enters service mode showing real-time temperature, element status, and sensor readings.

3. Relay Test: In service mode, you can activate individual relays to test each heating element independently. The display shows which relay is energized and the current draw.

4. Error History: Some Samsung ovens store the last 5 error codes. Access through the service mode menu by pressing the Clock button repeatedly to cycle through stored codes.

5. Door Lock Test: In service mode, press the Self Clean button to activate the lock motor without starting a clean cycle. This tests the lock mechanism in isolation.

Frequently Asked Questions

Q: My Samsung oven shows SE but all buttons seem fine. What should I check? A: The SE code detects electrical continuity on the touchpad membrane, not physical button movement. Even if buttons feel normal, the membrane contacts behind the glass can have internal shorts from moisture or heat damage. Try turning off the breaker for 30 minutes — if SE clears, it was moisture. If it returns immediately, the membrane needs replacement.

Q: Can I still use my Samsung oven if it shows tE or E-27? A: No. Without a functioning temperature sensor, the oven has no overheat protection. The control board either locks out the oven entirely (safety mode) or in rare cases allows heating with no temperature feedback, which creates a fire hazard. Replace the sensor before using the oven.

Q: Why does my Samsung oven overshoot the set temperature by 25–50 degrees? A: A small overshoot (15–25 degrees F) during preheat is normal — the element stays on until the sensor reads the target, and residual heat pushes temperature slightly higher. Overshoots of 50+ degrees F indicate a weakening temperature sensor giving low readings. Test the sensor resistance at room temperature (should be 1,080–1,100 ohms). Even a 10% deviation causes significant overshoot.

Q: Is it safe to run self-clean on my Samsung oven? A: Self-clean cycles reach 900+ degrees F and are the #1 cause of oven failures, particularly touchpad membrane warping (SE code), temperature sensor wire damage (E-27), and door lock failures (E-08). Many technicians recommend avoiding self-clean on Samsung ovens older than 5 years. Instead, use a commercial oven cleaner spray for similar results with less stress on components.

Q: My Samsung Flex Duo shows different temperatures in the upper and lower ovens. Is that a code? A: Not a code, but a symptom. Each oven cavity has its own temperature sensor. If one sensor is drifting, that cavity will read differently. Test each sensor independently — both should read approximately 1,080 ohms at room temperature. A 10% difference between them explains the temperature gap.

When to Call a Professional

Certain Samsung oven errors require professional service:

• E-OA / E-OB (overheating) — A welded relay is a fire hazard that requires board replacement and element testing to prevent recurrence.
• C-10 (communication error) — Multi-board diagnosis and replacement requires electronic expertise and sometimes model-specific firmware.
• 84E with gas ranges — Gas igniter and valve repairs should only be performed by licensed technicians due to gas safety risks.
• E-08 with door stuck locked — Forcing a locked oven door can break the latch mechanism. Let a professional release it safely.
• Repeated SE after touchpad replacement — May indicate moisture ingress behind the glass panel requiring resealing, or a failing control board.
• Any gas smell or visible sparking — Turn off the breaker and the gas supply immediately. Do not attempt repair.
