What P1
actually means.
P1 means probe 1 has failed. That is the sensor CellarPro uses to read the cellar and decide when to cool. Rather than stop, the unit switches to a timed auto-cycle, 12 minutes on and 8 off, and keeps that pattern until the probe is repaired or replaced.

What to do when P1 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 CellarPro's own guidance for P1 on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.
Check the cellar with your own thermometer in a glass of water over the next day; the timed cycle can drift warm on a hot day or cold in winter.
If an optional bottle probe is fitted, check its plug is seated, since it overrides probe 1.
Keep the door shut and 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
P1 does not mean the compressor or fans have failed; they keep running on the timer. It is also not the condenser probe, which is P3.

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 P1?
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.
