What Lo t1
actually means.
On True's 15-inch clear ice models, Lo alternating with t1 means the evaporator thermistor fell below 14°F (-10°C) within the first 5 minutes of the freeze. True links it to the water pump sprays or spray nozzles, since without water flowing over the molds the evaporator chills too quickly.

What to do when Lo t1 shows on the ice makerKind of codeIce making and harvest
The ice maker froze a batch and could not release it, or the harvest never started: the ejector arm or the twisting tray stalled, the mold heater did not loosen the cubes, or the arm that senses a full bin reported the wrong thing. Ice jammed against the arm and a bin pushed in crooked are cleared first; a motor module or a whole ice maker assembly comes after.
Usually leads toIce maker assembly replacement
A new ice maker module fitted in the freezer compartment or the door compartment, after the water, the temperature and the bin sensor have been proved good, so the new part is not blamed for an old problem.
Shows up asIce Maker Making Small or Hollow Cubes
The ice maker making small cubes, thin crescents, hollow shells with water inside or fragments that break apart in the bin tells you the mold is not getting a full fill.

Before you book,
in this order.
Each step comes from True Residential's own guidance for Lo t1 on its ice makers. Follow it to the end: the last card says whether this is a visit.
Turn the unit off and check that the spray nozzles are not clogged with scale.
Run the automatic clean cycle if scale is visible or the cleaning reminder is on.
If Lo t1 returns with clean nozzles and the pump spraying, book a visit.
