Samsung range and wall oven E-0A: oven overheating
E-0A means: Oven overheating.
How to fix E-0A
- Cut power at the breaker immediately.
- After cooling, meter the sensor (about 1080 ohms at room temperature; replace if far off).
- Inspect the control board for burnt relays; replace the board if the oven overheats with a good sensor.
When to stop and call a repairer
A stuck relay means the element will not turn off. Do not use the oven until fixed.
What it costs
Parts: Sensor $20 to $40; relay board $100 to $200.
Service: A home visit from an appliance technician runs $120 to $250 for diagnosis plus the part. Boards are the expensive part; sensors and switches are cheap.
Worth repairing? Sensor: yes. Board on an old range: compare quotes.
How to check the error log
Samsung ovens do not have a user-accessible error log. The code stays on the display until you fix the cause or cut power at the breaker for 3 minutes; if it returns after a reset, treat it as real.
Clear the log after a repair so you can tell whether the fault has really gone.
