What Does Error E07 Mean?

The Breville microwave E07 error indicates a malfunction related to the inverter power supply, often resulting in the microwave failing to start and producing unusual buzzing sounds. This error may occur after a power surge and is typically linked to issues such as a faulty inverter power board, a shorted magnetron, or loose wiring connections. To troubleshoot, try power cycling the microwave and testing it with a cup of water to check if the heating function works.

Common Symptoms:

  • Microwave displays E07 and will not start. [TechFaultFix](
  • Often noted after a power surge. [TechFaultFix](

Possible Causes

  • Inverter power supply board failure (low)
  • Shorted magnetron drawing excessive current (low)
  • Power surge damage to inverter components (low)
  • Loose inverter wiring connections (low)

How to Fix Error E07

DIY Fix Power cycle and basic checks

  1. Unplug the microwave from the wall outlet and wait 10–15 minutes. [TechFaultFix](
  2. Plug it into a properly grounded outlet (avoid surge strips or extensions). [TechFaultFix](
  3. Test heating with just a cup of water inside to see if the error persists. [TechFaultFix](

Technician Only Inspect and replace inverter power components

  1. Disconnect power and discharge internal capacitors safely. [TechFaultFix](
  2. Check inverter board for visible damage, replace if necessary. [TechFaultFix](
  3. Inspect magnetron and associated wiring for shorts or excessive current draw. [TechFaultFix](
  4. Secure any loose wiring connections in the inverter and associated circuits. [TechFaultFix](

Parts needed: Inverter power board, Magnetron, Internal wiring harness

🛑 When to Call a Pro:
  • If the error persists after basic power cycling.
  • If there are signs of component damage such as burning smell or visible scorch marks.
  • If you are not qualified to work around high‑voltage microwave components.
