Breville Intermittent Power Loss to Control Board

Microwave clock resets to 0:00 or flashes after each use or when opening the door.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose power cord connection, Failing internal power supply on control board, Loose wiring harness connector, Faulty line filter board

Safety: Unplug the microwave before moving or inspecting the cord.

User-level steps:

1. Check plug fit: Ensure the plug fits snugly in the outlet and is not loose.
2. Inspect cord: Look for damage or kinks in the power cord.
3. Try another outlet: Plug into a different outlet to rule out a loose receptacle.
4. Avoid wiggling: Do not move or wiggle the plug while the unit is operating.

If the clock continues to reset, the control board or internal power supply may be failing and should be serviced by a technician.
