Safety first: Disconnect power before accessing the control compartment.

Locate noise source: Remove the top cover and carefully identify which component is buzzing when the oven is heating (requires brief live test by a qualified person).
Tighten mountings: With power off, tighten screws securing the PCB, transformer, and relays to reduce vibration.
