What Does Error E05 Mean?

The Breville microwave error E05 indicates a malfunction, most commonly related to the magnetron, which prevents the microwave from heating food. Users may notice unusual buzzing sounds accompanying this error. The issue often arises during heating cycles, and a temporary reset by unplugging the microwave for 5–10 minutes may clear the error. However, persistent problems could signal deeper internal faults in the control board or temperature detection system.

Common Symptoms:

  • Microwave stops heating and displays E05
  • Error often appears during or immediately before heating cycles
  • Unplug/plug‑in reset temporarily clears error in some cases

Possible Causes

  • Internal control/temperature detection fault (low)
  • Control board or touchpad communication issue (low)

How to Fix Error E05

DIY Fix Basic checks and reset

  1. Ensure the door is fully closed and latched before operation
  2. Unplug the microwave from power for at least 5–10 minutes and then plug back in to attempt a reset
  3. Try a different power outlet to rule out external power issues

Technician Only Internal diagnostics

  1. Use a multimeter to test the internal temperature sensor/thermistor (if accessible) for proper resistance values
  2. Inspect control board and ribbon cable connections for signs of damage, corrosion or loose contacts
  3. Check internal high‑voltage components only if properly trained

Parts needed: Temperature sensor/thermistor, Control board, Ribbon cable connectors

🛑 When to Call a Pro:
  • If error persists after basic reset and visual checks
  • If door latch mechanisms do not engage properly
  • If unit fails to heat at all despite appearing functional
