What E1
actually means.
On CellarCool's Ceiling Mount, split and Ultimate models, E1 means the bottle probe is unplugged, badly connected at the PB1 terminal or defective. On the CX through-wall series the same code means the air-sensing probe has failed. Either way the controller stops reading the cellar and falls back to a timed pattern, 10 minutes off and 40 minutes on, until the probe is fixed.

What to do when E1 shows on the wine cellar cooling unitKind of codeSensors 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.

Shows up asWine Cellar Too Warm
A wine cellar too warm shows up slowly: the room smells of the house instead of cool stone, a bottle picked from a middle rack feels barely cooler than your hand, and the wall thermometer has crept from the mid 50s into the 60s over a week.

Before you book,
in this order.
Each step comes from CellarCool'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.
Identify your series from the rating plate: CX units sense air, the others use a probe in a bottle of liquid.
On a bottle-probe model, check the probe cable is plugged into its round connector and not crushed along the way.
Check the cellar with your own thermometer over the next day, since timed cooling does not follow the load.
On a CX, or if the plug is fine, book a visit to replace the probe.
Still there?
It usually turns into cellar controller and sensor repair. Book with the code and the model number.
What not to do
E1 is about the reading, not the refrigeration; the compressor is still running on its timer. On a CX, CellarCool treats the air probe as a service part rather than something to reseat at home.

Ducted cellar cooling unit
A self-contained cooling unit placed outside the cellar, in a mechanical room, attic or basement, that sends chilled air in and takes return air back through insulated ducts.
Split-system cellar cooling
An evaporator inside or beside the cellar and a condensing unit outside or in another room, joined by an insulated copper line set and charged on site.

Still showing E1?
When you book, type the code or the blink count as the controller shows it, add the full model number, and say what the thermometer in the cellar reads now — that gives the technician a head start.
