Liebherr MF1851 Freezer Column Repair
The MF1851 is the slimmest of the built-in freezer columns, an 18-inch, panel-ready unit that fits into narrow kitchen openings, pantry walls and bar areas where a full-width column will not go. A cabinet panel covers the door, and the freezer cools on its own, so it does not depend on a neighboring refrigerator.
Its slim opening leaves little room for air, which is where ageing starts. Dust collects at the vent, the compressor runs longer, and temperature inside slowly climbs. We check clearance and the condenser before anything else. Next comes the defrost system, because ice on the evaporator is the other common reason a frost-free freezer loses cold.
The control electronics get a read for stored alarms, and the InfinityLight lighting is tested apart from cooling. The panel comes off before we start. You see a written price first, and the work is covered by a 30-day workmanship warranty.
Access is tighter, so the panel and shelves come out first. The work itself follows the usual order: airflow, defrost system, sensors and control. We confirm the cabinet closes squarely before we leave.
Limited airflow forces long run cycles. Dust at the vent and a dirty condenser add to it, and we clear both, then measure how the freezer behaves over the next cycle.
No, the InfinityLight circuit is separate from the sensors and control that manage cooling. We test the light and its wiring on their own and verify temperature with a thermometer.
