What Flashing humidity with (!)
actually means.

When relative humidity passes setting 5, the remote flashes the humidity number with the (!) symbol until it falls back below the setting. The unit removes moisture as it cools, so persistent high humidity usually means moist air is getting into the room, the unit is not running enough to dry it, or a humidifier is overshooting.

What to do when Flashing humidity with (!) shows on the wine cellar cooling unit

Before you book,
in this order.

Each step comes from Wine Guardian's own guidance for Flashing humidity with (!) on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.

01

Check the door seal and any openings into the cellar, since a leak lets in moist air.

02

If a Wine Guardian humidifier is connected, check its setpoint (55% from the factory).

03

Look for condensation or mold on walls and racking; if you find it, book a visit to check the unit's run time and the room.

What not to do

Questions
about Flashing humidity with (!).

Can I clear Flashing humidity with (!) myself?
Check the door seal and any openings into the cellar, since a leak lets in moist air. If it comes back, it needs a visit.
Can a Wine Guardian lower humidity by itself?
The unit dries the air while it cools, but it has no separate dehumidify mode. If the room stays humid, the moisture source has to be found.
What humidity should a Wine Guardian cellar hold?
Wine Guardian sets its humidifier target at 55% from the factory. Most cellars do well from about 50% to 70%.
Why does the humidity alarm show after I open the cellar door often?
Each opening brings in warmer, wetter air. The reading should settle once the door stays closed and the unit runs a few cycles.
