EC07 is the lower cabinet thermistor. On a dual-zone Sub-Zero wine unit it tells the control how cold the lower section is, so the control is guessing while this code is active. The trigger is the same as on the upper probe: an open or short for 10 seconds or more, or repeated erratic readings. Sub-Zero wine cooler display · also shown as EC 07, EC7 What to do when EC07 shows on the wine cooler ### Kind of code Temperature sensors The control has lost a believable reading from one of its thermistors: the probe in a zone, the one on the cold plate or coil, or on some models the one watching the room. With no trustworthy number, the cabinet either chills the bottles far below cellar temperature or lets a zone drift warm. A sensor sitting in frost, pinched behind a rack or unplugged during a move is ruled out before a new one is ordered. ### Usually leads to Wine cooler thermostat and sensor repair Testing and replacing the thermostat or the temperature sensors that tell a wine cooler when to cool, when the cabinet runs too cold, too warm or back and forth. ### Shows up as Wine Cooler Error Code A wine cooler error code appears as letters and digits on the display, a flashing temperature, dashes where a number should be or a blinking symbol, sometimes with an alarm tone and sometimes while the cabinet stays perfectly cool. ### Make Sub-Zero Sub-Zero wine coolers repaired in place, with the collection kept closed and dark until the visit. ### Source Sub-Zero answer: Undercounter Wine (UW) error code EC 07 Undercounter Wine (UW) models and Classic (formerly Built-In, BW) wine storage, which show two-digit EC codes. Designer wine columns and Designer undercounter units report the same kind of problem with three-part codes instead. ## Before you book, in this order. Each step comes from Sub-Zero's own guidance for EC07 on its wine coolers. Follow it to the end: the last card says whether this is a visit. 01 Check the lower section with a thermometer in a glass of water left for an hour. 02 Cut power at the breaker for 30 seconds, restore it and watch for EC07. 03 If it returns, book a visit; until then keep door openings short so the lower zone stays as stable as possible. ### Still there? It usually turns into [wine cooler thermostat and sensor repair](https://winecoolerrepair.center/services/wine-cooler-thermostat-and-sensor-repair/). Book with the code and the model number. ### What not to do EC07 is not a warm alarm for the lower section; that is EC12. It is also not the lower coil probe, which reports as EC08. ## What you may notice with it. The wine cooler problems EC07 tends to arrive with.

Check the lower section with a thermometer in a glass of water left for an hour. If it comes back, it needs a visit. ### My upper zone is fine but EC07 is showing. Is that expected? Yes. Each section has its own air probe, so a bad lower probe leaves the upper section unaffected. Only the lower zone loses its accurate reading. ### Could EC07 come from a loose connection rather than a bad sensor? It can. An open reading comes from a broken wire or connector as easily as from the probe itself, which is why the circuit is tested before a part is ordered. ### Will the lower zone freeze my bottles with EC07? It is possible if the control misreads the lower section as warm and keeps cooling. Watch the lower racks with a thermometer and book a visit if the code stays. --- **[Read on the site: Sub-Zero EC07: the lower wine compartment sensor is not reading](https://winecoolerrepair.center/error-codes/sub-zero-ec07/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
