Liebherr R1400 Built-In Full Refrigerator in Stainless Repair

The R1400 is a stainless 24-inch built-in refrigerator that was sold in the US from 2006 to 2010, so it sits among cabinets in a home that is by now more than a decade old. Years of kitchen heat and Houston humidity wear its seals and its fan before anything else.
We open with the electronic control, reading the temperature it reports against a probe in the cabinet. If the two disagree we trace the sensor. Then we look at the gasket, the condenser airflow, and the evaporator fan, which on a full refrigerator is the part that keeps the top shelf cold.
ActiveGreen and Energy Star describe the original design, not its current condition, so an older unit with a leaking gasket draws more power than it was built to. We write down the price before any parts are ordered, and thirty days of workmanship coverage stand behind the repair.
The sensor can drift and report a temperature the cabinet is not holding. We place a calibrated probe among the shelves and compare. If the numbers differ, we replace the sensor before touching the control board.
The RB1400 adds BioFresh drawers; the R1400 has plain crisper-style storage. The cabinet size and shelf layout are the same, so service on the gasket, fan and defrost system is nearly identical.
Meltwater from the defrost cycle leaves through a tube behind the rear wall. Food debris can plug that tube, and the water then spreads across the cabinet floor. We flush the line and test the heater too.
Book in about a minute, or call the desk. Same-day windows inside the Loop on most days, next-day across the rest of Houston.
