Ice Maker Not Working is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Altitude changes how quickly a mould reaches temperature, and a unit running to a fixed cycle produces small or hollow cubes as a result.
Shows up as slow or stopped production, and is a plumbing-side issue rather than the ice-making mechanism itself.
The mechanical components that form and eject cubes wear out gradually.
Boiling point here is closer to 202°F than 212°F, which changes how anything that steams or boils behaves. A steam cycle that never seems to finish is often altitude rather than fault.
