Ambiano Unstable Low-Voltage Power Supply

Microwave clock loses time or resets intermittently without a full power outage.

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

Failing control board power supply capacitors, Loose power cord connection, Intermittent line voltage dips, Internal line filter issues

Safety first: Unplug the microwave before internal inspection.

Check plug and outlet: Ensure the plug fits tightly in the outlet and that the outlet is not loose.
Monitor for outages: Confirm there are no brief power interruptions in your home (lights flickering, other devices resetting).
Inspect control board: Remove the control panel and look for bulging or leaking capacitors on the control PCB.
Replace control board: If the power supply section shows signs of failure, replace the control board with an Ambiano-compatible part.
