Leisure range makes a rattling or buzzing noise from the rear or top when the oven is on.

Safety first: Isolate power before tightening screws or touching internal parts.

Steps:

• With the oven off and cool, check and tighten all accessible rear panel and side panel screws.
• Remove the top panel to inspect the cooling fan assembly. Ensure all mounting screws are tight and any foam pads or anti-vibration mounts are in place.
• Secure any loose wiring looms with cable ties so they do not vibrate against metal surfaces.
• If the noise is clearly from a relay or transformer on the PCB, this is usually harmless but can indicate wear; consider PCB replacement if noise is excessive.
