E-08 — Oven Not Heating
The control board commanded heat but never saw the cavity reach the expected temperature within the allowed time. On electric models this usually means a dead bake element or open element circuit.

The fix
Oven temperature sensor (RTD probe)
Oven temperature sensor error
Diagnose first: Sensor at the back of the oven cavity. Should read ~1080 ohms at room temp. Easy DIY - two screws and a plug connector.

How to fix it
- Shut off the breaker before working inside.
- Visually inspect bake and broil elements for blisters or breaks.
- With power off, test each element for continuity — open = replace.
- Inspect element spade terminals for burn damage and replace any pigtail with burned ends.
- Test the thermal fuse / hi-limit for continuity; replace if open.
- Verify 240V at the range terminal block (both legs hot to ground).
- If elements, wiring, voltage, and limits are good, replace the main control board (failed element relay).
Why it happens
Typical signs: E-08 displayed after preheat · Cavity stays cold or only weakly warm · Element doesn't glow · Bake works but broil doesn't (or vice versa)
- Failed bake or broil element Element coil burned open.
- Failed element relay on main PCB Relay not closing, no power to element.
- Open thermal fuse / hi-limit Safety device opened after prior overheat.
- Broken element wiring Spade terminal burned off at element.
- Incoming voltage low / one leg of 240V missing Element only gets 120V — heats very slowly or not at all.

Frequently asked questions
What does the E-08 code mean on a Samsung oven?
The control board commanded heat but never saw the cavity reach the expected temperature within the allowed time. On electric models this usually means a dead bake element or open element circuit.
What causes the E-08 code on a Samsung oven?
Failed bake or broil element: Element coil burned open. Failed element relay on main PCB: Relay not closing, no power to element. Open thermal fuse / hi-limit: Safety device opened after prior overheat.
Is it safe to keep using a Samsung oven with a E-08 error?
Limited use only. This is rated a serious-severity fault.
How do I fix E-08 on a Samsung oven?
Shut off the breaker before working inside. Visually inspect bake and broil elements for blisters or breaks. With power off, test each element for continuity — open = replace.
