Unit emits a metallic clicking or popping sound from the heater area during use.

Safety first: Unplug and cool before touching internal metal parts.

• Differentiate normal vs abnormal: Occasional light clicks from metal expansion can be normal. Loud or repetitive clunks suggest a mechanical issue.
• Inspect heater mounts: Check that the heater bracket screws are tight and the element is secure.
• Look for contact points: Identify any metal parts touching that should have clearance and adjust or bend slightly to eliminate rubbing.
• Clean element: Remove any visible grease blobs on the element that may sizzle or pop when heated.
