What LF
actually means.

Holding the Light Brightness button for 3 seconds switches the interior lights between two behaviors. LF is Automatic Mode, the default, where a sensor at the front vent lights the cabinet when the door opens. LN is Display Mode, where the lights stay on with the door closed and use more energy.

What to do when LF shows on the wine cooler

Before you book,
in this order.

Each step comes from Zephyr's own guidance for LF on its wine coolers. Follow it to the end: the last card says whether this is a visit.

01

Read the letters as a setting confirmation, not an alert.

02

Choose LN to keep the bottles lit behind the glass, or LF to light them only when the door opens.

03

Hold the Light Brightness button for 3 seconds to switch.

04

If the lights do not come on in either setting, book a visit to check the lights and the door sensor.

Cleared?

The display has gone quiet and the cabinet is back at its setting without a new part. Should the code reappear this week, or the reds start feeling warm again, book a visit and mention that it came back.

What not to do

LF is not a light failure; it is the default automatic setting. Lights that stay dark in both settings point to the LED strip, its driver or the door sensor.

What you may
notice with it.

The wine cooler problems LF tends to arrive with. Answer these at the wine cooler before anyone is booked.

All problems

No repair indicated

Nothing to repair.

A setting someone switched on, often by leaning on the touch panel or left over from the showroom floor, rather than a part that wore out: a demo mode that lights the display and the rack lamps while the cooling never starts, a Sabbath setting that turns off the lights and alarms, a child or control lock that ignores every key press, a reminder that the glass door stood open. The cabinet is fine, and its own keys or its manual switch the mode back off.

In Zephyr's own words

Display Mode will be signaled by showing “LN” on the display, and Automatic Mode will show “LF” on the display.

Questions
about LF.

Can I clear LF myself?
Read the letters as a setting confirmation, not an alert.
Why do my Zephyr lights only come on when I open the door?
The lights are in LF, the automatic default. Switch to LN if you want the bottles lit through the glass all the time.
Does LN use more energy on a Presrv?
Yes. Zephyr says the always-on display lighting uses more energy than the automatic setting.
My Zephyr lights no longer come on with the door open. What now?
Automatic lighting depends on a sensor at the front vent. If neither setting lights the cabinet, the sensor or the lights need checking.

Back to your everyday

Still showing LF?

When you book, copy the code or the blink pattern as the display shows it, add the whole model number, and say whether the bottles still feel cool — a code gives the technician a head start.
