Ice Machine Running but Not Making Ice

What it
usually means.

Every cube starts with four things working in order: water reaching the sump, the pump spreading it over a cold evaporator, the cooling system pulling that plate well below freezing, and a harvest that drops the finished slab into the bin. A machine that makes nothing has lost one of them, or has been told not to start. The simplest reasons are settings and use: the switch left on clean or off after the last sanitizing, the bin control reading full because a scoop, a bag or a pile of cubes is resting against it, or a delay after a power cut. Water is next: a supply valve closed during other work, a filter cartridge so clogged that it barely passes water, or low building pressure at the busiest hour. After that come the parts of the cycle itself, the inlet valve, the water pump, the thickness sensor and the hot gas valve, and last the cooling side: a condenser choked with dust or grease in a hot room, a dead fan, a remote condenser on a roof boxed in by leaves or debris, or a compressor that will not start.
