Microwave fan is very loud or continues running for a long time after cooking ends.

Steps:

• Understand cool-down: Many Clatronic models keep the cooling fan running for a short period after cooking to protect internal components. This is normal if it stops within a few minutes.
• Check for obstruction: Ensure nothing is blocking the vents that could cause the fan to work harder.
• Clean vents: Use a vacuum and soft brush to remove dust from intake and exhaust vents.
• Technician cleaning: If the fan is excessively loud, a technician can remove the cabinet (unplugged) and clean the fan blades and check for worn bearings or loose mounts.
