Oven displays E8 and may stop heating or not reach set temperature.

Safety first: Turn off power at the breaker. Heating elements can have sharp edges; wear gloves.

Step-by-step checks:

• Visual inspection of elements: Inspect the bake (bottom) and broil (top) elements inside the cavity for blisters, cracks, or burn-through spots.
• Continuity test: Disconnect the oven from power, remove the rear panel, and disconnect the element terminals. Measure resistance across each element; an open circuit indicates a failed element.
• Check thermal fuse: Locate any inline thermal cutoff or high-limit thermostat on the rear or top of the oven. Test for continuity; replace if open.
• Inspect wiring: Look for burnt or loose connectors at the element terminals and along the harness.

When to replace parts: Replace the bake element or broil element if open or visibly damaged. Replace the thermal fuse / high-limit thermostat if open. If all components are good, the control board relay may be faulty.
