Something that would be nice to see in the future would be a simple, cleanable filter on the fan inlet. We all have dust/hair/pet dander in our houses. A simple filter that you could take off and vacuum out would be awesome.
The EB3A is sealed and presuming Non-Serviceable Parts are inside - I doubt we’ll see this happening unless they change the housing design. People who camp and go to the beach should take precautions with placement of the unit keeping it away from gusts of sand and dirt. Accumulation of particulate matter will cause temps to rise within the unit for sure. Maybe add a fan filter to the opening when in risky locations. https://www.amazon.com/Dayton-Polyurethane-UL94HF-1-Replacement-31CC65-1/dp/B0748BQ6J8/ref=sr_1_20?crid=1FZMPI3D0VLF1&keywords=equipment+fan+filter&qid=1658329036&sprefix=equipment+fan+filter%2Caps%2C100&sr=8-20
