Samsung E-0A Error Code — Oven / Range Fault Fix

Error Code Explained

What Does the Samsung E-0A Error Code Mean?

The E-0A error code on a Samsung range indicates a power supply or power management fault detected by the main control board. The board monitors supply voltage and internal power rails. When a reading falls outside acceptable parameters — either from an external supply issue or an internal power circuit failure — E-0A is displayed and the range halts operation.

Root Causes

Common Causes of the Samsung E-0A Error Code

1

Supply Voltage Abnormality

The incoming AC supply voltage is too high or too low for safe operation.
2

Internal Power Board Fault

The power supply board that converts AC to the DC voltages used by the control electronics has failed.
3

Main Board Power Regulation Fault

A voltage regulator on the main control board has failed, causing internal power rail voltage to fall out of range.

Step-by-Step Guide

How to Troubleshoot the E-0A Error Code

⚠️

Safety First: Always disconnect the Oven / Range from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Check the circuit breaker

Verify the range circuit breaker is fully on and the outlet voltage is normal. A half-tripped breaker can cause abnormal voltage conditions.
2

Power reset

Turn off the breaker for 5 minutes and restore. If E-0A appeared from a transient power event, it may clear.

When to Call a Samsung Technician

⚠ Stop DIY if any of these apply

Persistent E-0A requires a technician to test supply voltage and internal board power rails to determine whether the fault is external (electrical supply) or internal (power board or main board).
