What BioFresh Sensor Fault means (liebherr monolith biofresh sensor)
A liebherr monolith biofresh sensor fault is reported as a symptom — sometimes with an F-series or BT code — on a Liebherr Monolith column with BioFresh Plus. BioFresh Plus holds precise low temperatures and humidity for produce; a sensor that reads out of range undermines that control.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your Liebherr Monolith. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- A BioFresh Plus zone drifts from its target
- Produce in the BioFresh drawers spoils faster
- A sensor fault may show in the app
- The zone temperature does not match the setting
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level fix from a problem that needs trained service and the correct Liebherr parts.
- Failed BioFresh sensor — the thermistor reads out of range
- Connector fault — a degraded sensor plug
- Wiring damage — a chafed lead
- Control fault — the board misinterprets the input
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where the sealed refrigeration system or live electrical parts are involved, and hand the rest to a qualified technician.
- Power the column off for two minutes and restore to clear a transient.
- Move sensitive produce out of the BioFresh Plus drawer.
- Check the SmartDevice app for any related notification.
- If the BioFresh zone keeps drifting, book service.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the biofresh plus sensor (thermistor), humidity control, and control board. The correct part for your Liebherr Monolith is matched from the model and serial number, and genuine Liebherr components are fitted rather than generic substitutes so that cooling performance, energy efficiency, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
A BioFresh Plus sensor fault needs a technician to measure the sensor and replace it or repair the harness. When the fix calls for trained service, book a visit through our scheduling page and our certified technicians will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your Liebherr Monolith. Keep the condenser and ventilation grille clean, avoid overloading or blocking air outlets, check the door gasket for a clean seal, and follow the Liebherr maintenance guidance for your model. Note when the symptom first appeared and what changed around the same time — a recent load, a warm room, a power event, or a relocation — because that detail often points a technician straight to the cause and keeps the repair simple.
