What E5
actually means.
On U-Line's clear ice and craft ice models, E5 in the service error log means thermistor 1 is shorted. A shorted sensor gives the control a false temperature, so it can misjudge the bin or the cycle it is managing.

What to do when E5 shows on the ice makerKind of codeTemperature sensors
The control lost track of how cold the ice mold or the ice compartment is, because a thermistor reads nonsense or its wire lost contact. Without that reading the ice maker cannot tell when a batch is frozen, so it stops or harvests at the wrong time. Frost packed around the sensor and a loose plug are checked before the sensor itself is changed.

The control board, the thermistors, the bin sensor and the wiring that decide when an ice maker fills, freezes and stops, tested and repaired when a light flashes, a code shows, a breaker trips or the ice never stops coming.
Shows up asIce Maker Making Too Much Ice
The ice maker making too much ice overfills the bin, pushes cubes into the chute, jams the door ice compartment or keeps the freezer drawer from closing.

Before you book,
in this order.
Each step comes from U-Line's own guidance for E5 on its ice makers. Follow it to the end: the last card says whether this is a visit.
Write down E5 and the model and serial numbers from the plate inside the unit.
Watch whether the bin overfills or stays low; that tells the technician how the bad reading is affecting the unit.
Book a visit to have the thermistor and its harness tested.

It usually turns into ice maker control and sensor repair. Book with the code and the model number.
What not to do
E5 is not the same as E1. E1 means the sensor circuit is open, while E5 means it is shorted.

Still showing E5?
Book with the code or the blink pattern written exactly as the ice maker shows it, the full model number, and whether there is any water on the floor — when there is a code, that is where the diagnosis starts.
