Samsung Oven Error Codes: What They Mean and How to Fix Them
- E08 — no heat: check bake/broil elements (or igniter on gas), temp sensor, wiring.
- E-OA — overheating: cool down, check temp sensor and stuck relay on the control.
- E27 / E28 — bad temp sensor or harness fault.
- SE — stuck or dead key on the touch panel.
- LE — low or unstable voltage (power supply issue).
- E54 — main control board fault.
- E-55 — panel ↔ control communication fault.
- cE-56 — internal control error.
- E-OE — door lock did not lock or unlock.
Safety first: switch the breaker off before removing panels or testing parts. 240V can be dangerous.

Before you start
- Turn the oven off at the breaker for 2–3 minutes, then back on. Many codes clear after a clean power reset.
- Make sure the wall outlet and cord are not hot, burnt, or loose.
- Have a flashlight, #2 Phillips, nut driver, and a multimeter (ohms) ready.
- Find your model/serial sticker (door frame, drawer area, or rear panel). Take a photo for reference.
Fast reference table
Code | Meaning | First checks | Typical symptoms |
---|---|---|---|
E08 | No heat | Elements/igniter, temp sensor, wiring | Oven cold, preheat stalls |
E-OA | Overheating | Let cool, temp sensor, stuck relay | Runs too hot, burning smell |
E27 / E28 | Temp sensor fault | Sensor plug, harness, sensor ohms | Wild temps, long preheat |
SE | Defective key | Dry/clean panel, reseat ribbon | Buttons stuck or dead |
LE | Low voltage | Dedicated circuit, terminals tight | Dim display, random reboots |
E54 | Control fault | Board plugs, ground, reset | Random errors, no response |
E-55 | Panel comms | Ribbon cable, corrosion | Panel unresponsive |
cE-56 | Internal control | Reset; test board | Returns after reset |
E-OE | Door lock error | Lock motor/switch, latch path | Door won’t lock/unlock |
E08 — Oven not heating
What it means: The oven is not reaching set temperature.
Likely causes: open bake/broil element (electric), failed igniter or gas valve (gas), bad temp sensor, loose or burnt wiring, or a control relay fault.
DIY steps:
- Reset power. Try Bake then Broil. Note which one fails (helps narrow the faulty circuit).
- Elements (electric): look for blisters or breaks. Test continuity (no continuity = replace). Typical element resistance is often in the tens of ohms.
- Igniter (gas/dual fuel): should glow bright within ~30–60s. If it glows but the burner never lights, the igniter is usually weak. Replace the igniter first.
- Temp sensor: reseat the connector. See “How to test the temp sensor” below.
- Inspect wiring from parts to the control. Replace burnt spades or melted wires.
E-OA — Overheating
What it means: The oven got too hot or the board “thinks” it did.
Likely causes: bad temp sensor, shorted sensor harness, or a stuck heater relay on the control board.
DIY steps:
- Let the oven fully cool. Do not use self-clean until fixed.
- Check the temp sensor value (see table below) and the harness for cuts or shorts to chassis.
- If it overheats again with a good sensor, the control relay may be stuck closed. Board service/replacement may be needed.
E27 / E28 — Temperature sensor fault
What it means: The control sees an open, short, or out-of-range reading.
DIY steps:
- Kill power. Pull the sensor plug at the back wall inside the oven or from behind.
- Measure resistance at room temp. If way off (see table), replace the sensor.
- Check the harness from sensor to control for pin damage or broken insulation.
SE — Defective key
What it means: A touch key is stuck or not reading.
- Reset power. Clean and dry the glass.
- Open the console. Reseat the flat ribbon. Look for corrosion or kinks.
- If still bad, replace the touch panel (and ribbon if worn).
LE — Low voltage
What it means: Power supply dipped below spec or is unstable.
- Use a dedicated circuit. Do not share with other heavy loads.
- Inspect the terminal block on the oven. Tighten loose lugs. Replace burnt parts.
- If the home supply is unstable, speak with an electrician.
E54 — Electronic control board error
What it means: Internal control fault.
- Reset power. Reseat all board connectors. Check for burnt spots near relays.
- If the error returns or functions are random, the board likely needs repair or replacement.
E-55 — Touch panel communication error
What it means: The panel and board are not talking.
- Power cycle. Reseat or replace the ribbon cable first.
- Check for moisture or corrosion in the console.
- If still failing, test/replace the panel and/or main board.
cE-56 — Internal control issue
What it means: A control circuit failed self-check.
- After a reset, if the code returns, plan for board diagnosis and likely replacement.
E-OE — Door lock error
What it means: The door lock did not move or did not report the correct state.
- Wait until the oven is cool (especially after self-clean).
- Check the latch path for debris or a bent hook.
- Listen for the lock motor. If silent, test the motor and door lock switch.
- Manually release the lock (access varies by model; often from the top once the console is open).
How to test the temperature sensor (easy)
- Power off. Unplug sensor from its connector.
- Measure resistance (Ω) across the two sensor pins.
Approx. Temp | Typical Reading* |
---|---|
20–25 °C (room) | ~1,000–1,100 Ω |
100 °C | ~1,350 Ω |
260 °C | ~1,650 Ω |
*Values are typical for many Samsung oven probes; check your model’s service data if available.
Electric vs. gas / dual-fuel note
- Electric ovens: heat comes from bake/broil elements controlled by relays.
- Gas or dual-fuel ovens: no glow or no flame usually points to the igniter. A weak igniter often glows but never opens the gas valve—replace the igniter first.
Signs of a control board problem
- Heats when it should be off (stuck relay).
- Random beeps/restarts, dead display, or codes that return after a clean reset.
- Visible burn marks near relays or a hot electrical smell.
Prevent issues
- Avoid running self-clean right before a big event; it runs very hot and can expose weak parts.
- Keep the oven cavity and door gasket clean so heat control stays stable.
- Do not slam the door; it can damage the lock and the panel.
- Use the right circuit and tight electrical connections.
What to note before calling
- Exact error code(s) and when they showed up (after self-clean, during preheat, etc.).
- Which functions fail (Bake, Broil, Fan, Lock).
- Any smells, clicks, or buzzing you hear.
- Model and serial number, and a quick photo of the cord/terminal block if it looks burnt.
When to call a pro
- Codes return right after a reset.
- You find burnt wiring, a cracked element, or a swollen/burnt control board.
- Door stays locked or the unit overheats.
