What HI
actually means.
HI flashes when the temperature input goes above 99°F. A cellar anywhere near that hot would normally have tripped the overheat shutdown first, so we test the sensor, its connection and the position of any bottle probe before anything else.

What to do when HI 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 asCellar Cooling Unit Error Code
A cellar cooling unit error code appears as letters or digits on the controller, a flashing reading, a blinking light on the unit, or an alarm tone, sometimes while the cellar still holds its temperature.

Before you book,
in this order.
Each step comes from Breezaire's own guidance for HI on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.
Check the cellar with a separate thermometer to see whether the room is actually hot.
If a bottle probe is fitted, make sure it has not ended up near the warm exhaust side or a light fixture.
Do a manual reset by holding WARMER for at least 5 seconds and see whether the reading comes back to normal.
If HI stays, book a visit to test the sensor.

What not to do
HI is not the AL warning, which flashes when a working sensor sees the cellar above your alarm point. If the room really is hot and the unit has stopped, the display shows OH.

Breezaire wine cellar cooling unit repair
Through-the-wall cellar cooling unit
A self-contained box set into an opening in the cellar wall: its cold face blows into the wine room, and its warm face breathes out into the room next door.
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.
In Breezaire's own words
if above 99°F (37°C) it will flash “HI”.

Still showing HI?
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.
