Liebherr’s BioFresh compartments are designed to hold food near 0°C with elevated humidity, extending freshness well beyond a standard refrigerator drawer — which is exactly why a BioFresh sensor problem (F0) is worth taking seriously even though the main cabinet keeps cooling normally. The drawer’s climate control depends on a dedicated sensor separate from the main compartment’s, so a problem there doesn’t always show up as an obvious sign beyond food spoiling a bit faster than expected.
If you notice produce or meat in the BioFresh drawer not lasting as long as it used to, it’s worth having the sensor checked rather than assuming the food itself was the problem.
