Viking Control Board Power Stability Issue

Microwave clock or timer loses time or resets intermittently.

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

Unstable household power, Loose power cord connection, Failing control board power supply, Electrical noise on line

Safety: Unplug the microwave before accessing internal wiring.

Check outlet: Ensure the Viking microwave is plugged into a dedicated, properly grounded outlet. Avoid using extension cords.
Secure plug: Make sure the plug fits tightly in the outlet and does not wiggle.
Power quality: If other devices on the same circuit flicker or reset, have an electrician check the circuit.
Control board: If power is stable but the clock still resets, the control board's internal power supply may be failing and require replacement.
