What E12
actually means.
T1 sits at the evaporator outlet and tracks how cold the plate gets. When it reads over 113°F, True's first suspects are warm incoming water and a hot room, then the probe itself.

What to do when E12 shows on the ice machineKind of codeCooling system
The board saw temperatures or pressures that the sealed system should never reach: a discharge line too hot, a suction side that never cools, or a compressor that starts and stops on its overload. A dirty condenser can push a healthy system into this family, so it is the first thing to rule out; a low charge, a leak or a tired compressor is not. On many current machines that system holds R-290, which is flammable, and only a technician opens it.
Usually leads toIce machine compressor and sealed system repair
The compressor, its start parts and the sealed system, including machines on flammable R-290, tested for pressure and leaks and repaired by the maker's procedure.
Shows up asIce Machine Error Code or Flashing Light: What It Is Telling You
An ice machine error code may show as a number on a small display, a pattern of blinking lights on the control board, a colored light on the front, or a machine that stops with one indicator flashing.

True ice machine visits begin with the installation: the supply, the drain fall and the clearance the machine needs to cool.

Before you book,
in this order.
Each step comes from True Residential's own guidance for E12 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Check that the head is plumbed to a cold water line, not a hot or mixed one.
Check the room temperature and airflow around the head.
If the water and room are normal, book a visit so T1 can be measured with a meter.

What not to do
E12 is a high reading, while E13 is the opposite limit, below -20°F, and E1 means T1 is open or shorted. It does not mean the machine is harvesting too long; that is E26.

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
