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.

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.
