Short answer: If a draw-activated device stops responding, inspect only visible exterior vents and packaging as the maker directs. Do not probe the sensor or open the battery housing.
What you can check
Remove factory covers or plugs according to the packaging. Wipe loose lint from exterior openings with a clean, dry soft cloth. If a pod is designed to be removed, reseat it according to the instructions.
When to stop
A device that leaks, heats unexpectedly, activates on its own, or remains unresponsive should be set aside and referred to the seller or manufacturer. Avoid needles, compressed air and liquid cleaners in sealed openings.
For battery precautions, see the FDA battery safety guidance. Follow the instructions for your exact device.
