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. U-Line ice maker display What to do when E5 shows on the ice maker ### Kind of code Temperature 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. ### Usually leads to Ice maker control and sensor repair 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 as Ice 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. ### Make U-Line U-Line undercounter ice maker service, including cleaning, descaling and drain repair. ### Source U-Line User Guide & Service Manual, UHCL115 15-inch clear ice model (u-line.com PDF) U-Line 15-inch clear ice (HCL, OCL, ACP) and craft ice (RCC) models. U-Line says all errors are logged in memory, but only the door error shows on the display with a tone; the others are read from the error log in service mode. ## 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. 01 Write down E5 and the model and serial numbers from the plate inside the unit. 02 Watch whether the bin overfills or stays low; that tells the technician how the bad reading is affecting the unit. 03 Book a visit to have the thermistor and its harness tested. ### Still there? It usually turns into [ice maker control and sensor repair](https://icemakerrepair.center/services/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. ## What you may notice with it.

Write down E5 and the model and serial numbers from the plate inside the unit. If it comes back, it needs a visit. ### Is E5 on a U-Line serious? It will not flood or damage anything by itself, but the control is working from a false temperature. Ice level or cycle timing can go wrong until the sensor is fixed. ### Can moisture cause E5 on an outdoor U-Line ice maker? Water at a connector is one way a sensor circuit can read shorted, and U-Line greases thermistor connections to keep them dry and clean. A technician checks the connector before condemning the sensor. ### Does replacing a U-Line thermistor clear E5 from the log? The log keeps past errors until it is cleared in service mode. After the repair, the technician clears it so any new code stands out. --- **[Read on the site: U-Line E5 in the error log: thermistor 1 shorted](https://icemakerrepair.center/error-codes/u-line-e5/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
