Garage door opener emits a burning smell or visible smoke during or after operation.

Safety first: Immediately unplug the opener and do not operate it again until inspected. Risk of fire or electric shock.

Steps to inspect:

• Identify source: After cooling, remove the cover and look for charred components, melted insulation, or discolored circuit board areas.
• Check motor: If the smell is strongest at the motor housing, the motor windings may be burned. Replace the motor assembly.
• Inspect capacitor: Look for bulging or leaking capacitor. Replace if damaged.
• Examine wiring: Tighten any loose high-current connections and replace burned wires.
• Replace damaged assemblies: Any visibly burned logic board or motor must be replaced with Motorlift-approved parts. Do not attempt to repair burned boards at component level.
