What Does Error E08 Mean?

The Breville microwave error code E08 indicates a malfunction in the magnetron, leading to failure in heating food and unusual humming sounds. This error may manifest as the microwave running briefly before stopping or failing to heat entirely. Possible causes include a blown high-voltage fuse, a fault in the temperature sensor, or issues with the turntable motor. Addressing these issues promptly can help restore functionality.

Common Symptoms:

  • Microwave runs briefly then stops with E08 displayed
  • Microwave runs but does not heat
  • Turntable may not rotate when E08 appears (per one community list)

Possible Causes

  • High‑voltage fuse blown (no current to magnetron) (medium)
  • Temperature sensor / thermal protection fault (medium)
  • Turntable motor/rotation error (low)

How to Fix Error E08

DIY Fix Basic checks and reset

  1. Unplug the microwave from power for 5–10 minutes to clear transient faults.
  2. Check that the turntable is seated correctly and can rotate freely.
  3. Plug the microwave back in and test a short heating cycle to see if the error persists.

Technician Only Inspect high‑voltage fuse and magnetron circuit

  1. Disconnect power and remove microwave outer covers per service manual.
  2. Test the high‑voltage fuse for continuity; replace if open.
  3. Measure magnetron and diode circuits with appropriate equipment; replace faulty components.
  4. Verify thermal sensor/thermostat continuity and correct placement.
  5. Reassemble and test under supervision.

Parts needed: high‑voltage fuse, magnetron (if faulty), diode, temperature sensor/thermal fuse

🛑 When to Call a Pro:
  • If you cannot safely access internal components
  • If the error reoccurs immediately after simple reset
  • If high‑voltage components are suspected
