VERIFIED
F4 indicates a freezer-compartment evaporator sensor fault on the platforms that document this token.
Owners seeing F4 note the display and measure the affected zone separately.
Seal contact is verified first when F4 appears on the panel.
One power cycle is tried if F4 may be transient.
Ongoing F4 with poor temperatures leads to testing the documented part.
Controller response for the indicator is checked against series notes. This applies to F4.

Sensor testing for the token follows after basic checks. This applies to F4.
The token is recorded with zone readings before documentation is opened. This applies to F4.

Frequently asked questions
No. Documentation shows platform and model differences.
Check measured temperatures. Move food if readings are unsafe.
A single power cycle is safe to try. Record whether the code returns.
Model compatibility: Liebherr reuses codes across series and model years, so F4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
