Viking Relay or Transformer Noise

Viking oven emits a buzzing or humming noise from the control area when heating.

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

Worn or vibrating relays on EOC, Loose mounting of control board, Noisy low-voltage transformer, Induced vibration from cooling fan

Safety: Disconnect power before touching the control board or mounting hardware.

Steps:

Remove the control panel and identify the source of the noise while the oven is operating (use extreme caution and insulated tools if testing live).
Tighten mounting screws for the EOC and any transformers or relays to reduce vibration.
If a specific relay is chattering or excessively loud, the EOC may need replacement.
Check that the cooling fan is balanced and not transmitting vibration to the control panel.
