Sub-Zero and built-in refrigerator repair in Sherman Oaks

How built-in refrigerators differ

A built-in unit is fixed into the cabinets, so all its heat must leave through a grille, usually at the top. Sub-Zero models use two separate cooling systems, one for the refrigerator and one for the freezer, each with its own compressor and coil. One section can fail while the other works normally.

Common problems

• Warm in summer, fine in winter. A dirty condenser. Dust and kitchen grease clog the coil behind the grille, and the unit cannot shed heat. In the Valley heat this shows up fast. The condenser should be cleaned every 6 to 12 months.
• Refrigerator section warm, freezer normal, or the reverse. A fault in one of the two systems: evaporator fan, defrost parts, a control fault or a sealed system problem.
• Running nonstop. Dirty condenser, a failing condenser fan or worn door gaskets that let warm air in.
• Ice maker stopped. The ice maker, the inlet valve or the water filter. See ice maker not making ice.
• Water on the floor or inside. A blocked defrost drain or a leaking water line. See refrigerator leaking water.
• Condensation or frost at the door. Torn or flattened door gaskets.

South of Ventura Boulevard

Many homes in the hills south of Ventura Boulevard have built-in refrigeration that is 15 to 25 years old, often installed during a kitchen remodel. These units were built to be serviced. With a clean condenser, good gaskets and working fans they keep running for many more years.

What to do before the visit

• Note the model and serial number. On a Sub-Zero the tag is inside the refrigerator section, near the top hinge.
• Note which section is warm and the temperatures on the display.
• If a service indicator is lit, tell us what it shows.
• Do not turn the unit off unless it is leaking or making a loud noise. We need to see how it is running.
