E1 means the controller has lost the bottle probe, the sensor in liquid that it normally cools to. The probe may be unplugged at its round connector, loose where it meets the board or controller, or failed. WhisperKOOL's safety logic then runs the compressor on a fixed pattern, off 10 minutes and on 40, so the cellar keeps some cooling while the code stays on the screen. WhisperKOOL wine cellar cooling unit display · also shown as “E1” What to do when E1 shows on the wine cellar cooling unit ### Kind of code Sensors and probes The controller has lost a sensible reading from one of its probes: the one sampling the cellar air, the one on the evaporator coil, or on a remote probe the lead that runs out to a rack. With no number it can trust, the unit may chill the room well below 55°F, stop and start every few minutes, or run on without end. A probe unplugged during a rack install, pinched behind a board or sitting in a draft from the door is ruled out before a new one is ordered. ### Usually leads to Cellar controller and sensor repair Getting the controller, its display and its probes to read the cellar truthfully and call for cooling at the right time. ### Shows up as Wine Cellar Too Cold A wine cellar too cold feels like stepping into a walk-in: the thermometer sits in the 40s, bottles come out beaded with water, and the unit keeps running long after the room should have been satisfied. ### Make WhisperKOOL WhisperKOOL systems serviced where they are installed, whether the cellar is warming, the coil is frosting or the unit never rests. ### Source WhisperKOOL Platinum Split 4000/8000 owner's manual (01/2022) Shown by both WhisperKOOL controller families: the digital controller on Platinum Split, Ceiling Mount, Extreme tiR and Phantom, and the SC PRO and Slimline LS through-the-wall controller. ## Before you book, in this order. Each step comes from WhisperKOOL's own guidance for E1 on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit. 01 Find the bottle probe in the cellar and check that its cable is plugged into the round connector on the unit. 02 Follow the cable for a crushed or cut section, especially where it passes racking or a door. 03 Put a thermometer in a bottle of water on a middle rack and check it over a day; the timed cycle can drift warm or cool. 04 If the plug is seated and E1 stays, book a visit to test and replace the probe. ### Still there? It usually turns into [cellar controller and sensor repair](https://winecellarrepair.center/services/cellar-controller-and-sensor-repair/). Book with the code and the model number. ### What not to do E1 does not mean the compressor or refrigerant has a problem; the unit is cooling on a timer. It also never shows in the alarm folder: on the digital controller it stays on the main screen until the probe reads again. ## What you may notice with it.

Find the bottle probe in the cellar and check that its cable is plugged into the round connector on the unit. If it comes back, it needs a visit. ### Can my WhisperKOOL keep the cellar cool with E1 showing? For a while, yes. The timed 10-off, 40-on cycle keeps it running, but it cannot correct for a hot day or a full load of warm bottles, so check the room with your own thermometer. ### Where is the bottle probe on a WhisperKOOL? It sits in a small bottle of liquid in the cellar, on a cable that plugs into a round connector on the unit. On the digital controller that cable runs to the PB1 terminal on the circuit board. ### Is the WhisperKOOL bottle probe something I can replace myself? Reseating the plug is easy. Replacing the probe means opening the unit to reach the board terminal on most models, which is best done on a visit. --- **[Read on the site: WhisperKOOL E1: the bottle probe is unplugged or has failed](https://winecellarrepair.center/error-codes/whisperkool-e1/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
