What dF
actually means.

dF is a status message, not an alarm. Wine-Mate's earlier controller puts the unit into defrost every day for about 30 minutes and shows dF while it runs; holding the defrost button for more than 5 seconds starts one by hand. On current controllers the defrost light comes on instead, and the default interval is every 12 hours for up to 30 minutes.

What to do when dF shows on the wine cellar cooling unit

Before you book,
in this order.

Each step comes from Wine-Mate's own guidance for dF on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.

01

Wait: the older manual gives 30 minutes as the most a defrost should take.

02

Look again after about 15 minutes to see whether the unit has gone back to normal cycling.

03

If dF stays on far longer than half an hour, or the coil is still iced afterward, book a visit.

Cleared?

The controller has stopped showing the code and the cellar is drifting back to its set point without any new part. If the code returns within the week, or the room creeps warm again, book a visit and tell us it came back.

What not to do

dF does not mean the unit has stopped working, even though the compressor is off. A unit that is off with no dF and no lights points to power or the controller instead.

All problems

No repair indicated

Nothing to repair.

Something the controller was told to do, not a part that wore out: a display switched between Fahrenheit and Celsius so 13 looks alarming, a set point or differential changed by someone leaning on the keys, a keypad lock that ignores every press, a standby state left on after a power cut, a reminder that service is due. The unit is fine, and the controller's own keys or its manual put it back.

In Wine-Mate's own words

This is not a alarm signal, but rather an indication that the unit is in defrost mode

Questions
about dF.

Can I clear dF myself?
Wait: the older manual gives 30 minutes as the most a defrost should take.
Why is my Wine-Mate not cooling while dF is showing?
Wine-Mate lists defrost among the reasons a unit is not running, since the coil needs a break to shed its frost. Cooling picks up again when the cycle ends.
Can I start a defrost myself on a Wine-Mate?
Yes. On the older display, hold the defrost button for more than 5 seconds; on the current five-button controller, press and hold the defrost key until the defrost light comes on.
What if the Wine-Mate coil keeps icing even with defrost?
On current controllers Wine-Mate suggests setting FnC to C-y, idF to 4 and MdF to 20, which defrosts more often. If ice keeps forming after that, the airflow or the refrigerant side needs a technician.

Back to your everyday

Still showing dF?

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.
