Samsung Oven E-0A — Oven Overheating

Samsung Oven · Error code E-0A

What E-0A Means

Alternate display of an overheating condition on older Samsung electric ranges. Functionally equivalent to C-21 — cavity temperature exceeded safe threshold.

Symptoms

  • E-0A on display, heat shuts off
  • Oven runs hotter than setpoint
  • Repeats on retry
  • May trip thermal fuse

Common Causes

1
Failed temperature sensor

RTD drifted and the relay overdrove the element.

2
Welded bake/broil relay on main PCB

Relay stuck closed.

3
Blocked oven vent

Cavity can't release heat.

4
Shorted element

Element grounded and stays energized.

How to Fix It

  1. Stop using the oven until repaired.
  2. Cut power at the breaker and let the cavity cool.
  3. Test the temperature sensor (~1080 ohms at room temp); replace if out of spec.
  4. Inspect and clear the oven vent.
  5. Test elements for short to ground; replace if shorted.
  6. If sensor and elements check out, replace the main control board (relay stuck closed).
