Liebherr SCB5790IM Fridge-Freezer with BioFresh Professional for Fish and Meat Repair

Liebherr refrigerator

Most common issues on this model

  1. BioFresh drawer too cold or too moist
  2. Fridge warming when the fan or damper stalls
  3. Freezer frost that signals a failed defrost cycle
  4. Water in the drawer area from a blocked drain
  5. Control board that fails to read the sensors

The SCB5790IM adds BioFresh Professional to a NoFrost fridge-freezer, which gives it drawers that hold cold close to 32°F. That narrow range leaves little room for error, so a sensor that has drifted by a degree can freeze lettuce or let meat age too quickly.

We therefore begin with temperature readings in the drawers themselves rather than the main compartment, then compare them to the control display. After that we move to the airflow and defrost parts that feed the drawers, plus the drain and door seals. Humidity sliders and drawer seals are the last checks. Whatever we find, the price is given in writing first.

Tell us what you store in the drawers, whether fish, meat or produce. It helps us judge how tightly the temperature must be held, and we aim the repair at that.

SCB5790IMSCB5790IM questions
Why is my BioFresh drawer freezing vegetables?

The drawer sits near 32°F, so a small sensor drift or a blocked airflow path tips it below freezing. We measure the actual temperature, check the humidity slider and replace the sensor if it reads wrong.

Does BioFresh Professional need special servicing?

The drawers use the same cooling parts as the fridge, but their tolerance is tight. We test with a calibrated probe and look at the drawer seal, which has to close fully to hold humidity.

Is frost in the freezer a sign that BioFresh is failing?

No. Frost points to the freezer defrost system, which is separate from the drawers. We check the heater, the sensor and the fan, and the BioFresh drawers are tested alongside.
