--- title: "True clear ice maker showing E2: condenser thermistor" description: "What E2 means on True clear ice makers, what to check before booking, and when it is not a failure at all." url: "https://icemakerrepair.center/error-codes/true-e2/" --- # True clear ice maker showing E2 On True's 15-inch clear ice models, E2 is thermistor 2 failure. ## What E2 actually means. On True's 15-inch clear ice models, E2 is thermistor 2 failure. That thermistor is on the condenser outlet tube and cycles the fan motor; E2 means the probe has a bad or loose connection, so the control cannot manage the fan properly. True Residential ice maker display What to do when E2 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 No Ice Coming From the Ice Maker The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally. ### Make True Residential True Residential undercounter ice maker repair, from a slow harvest to water that will not drain. ### Source True ADA-height 15-inch TRUE ICE (TUIADA-15-D) install guide (true-caliber.com PDF) True Residential 15-inch clear ice models (TUI-15-D, and the ADA-height TUIADA-15-D).

Write down E2 and the model and serial numbers. If it comes back, it needs a visit. ### What part does E2 point to on a True ice maker? Thermistor 2 on the condenser outlet tube. It tells the control when to run the condenser fan. ### Can E2 make my True ice maker run hot or loud? If the control cannot read the condenser temperature, the fan may not cycle as designed. That can change how the unit sounds and how well it cools. ### Is E2 something I can fix on my True? No. True's action is to contact a service company to test and replace the probe or its connection. --- **[Read on the site: True clear ice maker showing E2: condenser thermistor](https://icemakerrepair.center/error-codes/true-e2/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
