--- title: "Sub-Zero EC08: the sensor on the freezer coil has stopped reporting" description: "What EC08 means on Sub-Zero EC08: the sensor on the freezer coil has stopped reportings, what to check before booking, and when it is not a failure at all." url: "https://freezerrepair.center/error-codes/sub-zero-ec08/" --- # Sub-Zero EC08: the sensor on the freezer coil has stopped reporting EC08 (07’s neighbor, printed as 08 on IC-27 and UC models) refers to the freezer evaporator thermistor, the sensor clipped to the cooling coil that lets the control judge when defrost is complete. ## What EC08 actually means. EC08 (07’s neighbor, printed as 08 on IC-27 and UC models) refers to the freezer evaporator thermistor, the sensor clipped to the cooling coil that lets the control judge when defrost is complete. When it reads open or shorted for 10 seconds or more, or keeps giving erratic values, the control logs this code. Sub-Zero freezer display · also shown as EC 08, 08 What to do when EC08 shows on the freezer ### Kind of code Temperature sensors The control lost its reading of how cold the cabinet, the coil or the air around the freezer is, because a thermistor reports nonsense or its wire came loose. Without that number the control either runs the compressor without stopping or lets the cabinet drift warm. A sensor packed in frost and a connector loosened by a move are checked before the sensor itself is replaced. ### Usually leads to Freezer thermostat and temperature control repair Repairing the dial thermostat or the sensor and control that decide when a freezer cools, so it stops running without end or quitting too early. ### Shows up as Freezer Error Code A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running. ### Make Sub-Zero Sub-Zero freezers repaired in the home, with the food kept shut in while the cause is found. ### Source Sub-Zero answer: 600 or 700 Series EC07 or EC08 600 and 700 Series (EC08 or EC 08), IC-27 integrated columns and UC undercounter models (08). ## Before you book, in this order. Each step comes from Sub-Zero's own guidance for EC08 on its freezers. Follow it to the end: the last card says whether this is a visit. 01 Look through the vents at the back of the freezer for a thick white frost coat, which suggests defrost has stopped ending properly. 02 On IC-27 and UC models, turn the breaker off for 30 seconds and on again, then check whether 08 returns. 03 Book a visit if the code stays, and give the technician the code and the freezer temperature from the display. ### Still there? It usually turns into [freezer thermostat and temperature control repair](https://freezerrepair.center/services/thermostat-and-temperature-control-repair/). Book with the code and the model number. ### What not to do EC08 does not mean the cabinet sensor has failed; that is EC07. It also does not by itself mean the defrost heater is broken, which the 20-series codes report. ## What you may notice with it. The freezer problems EC08 tends to arrive with.

Look through the vents at the back of the freezer for a thick white frost coat, which suggests defrost has stopped ending properly. If it comes back, it needs a visit. ### Why would a bad coil sensor on a Sub-Zero cause frost? The evaporator thermistor tells the control when the coil is clear during defrost. Without a sound reading, defrost may not end at the right time, and frost can build on the coil and choke the airflow. ### Is it safe to keep food in a Sub-Zero freezer showing EC08? Usually yes for the short term, since the compressor still runs. Check the food temperature daily until the sensor is replaced, because a coil that frosts over will slowly lose cooling. ### What is the difference between EC07 and EC08 on Sub-Zero? EC07 is the sensor that reads the air in the freezer compartment; EC08 is the one clipped to the freezer evaporator coil. They are different parts in different places. --- **[Read on the site: Sub-Zero EC08: the sensor on the freezer coil has stopped reporting](https://freezerrepair.center/error-codes/sub-zero-ec08/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
