The short answer
Sub-Zero Repair Specialists repairs Sub-Zero, Viking and Thermador refrigerators in Compton, CA, coming from our base in nearby Carson. We diagnose the cause in your kitchen, explain the repair in plain terms, and fix it on site when we have the part on hand.
When a built-in refrigerator stops holding temperature, the food inside is on a clock. Sub-Zero Repair Specialists repairs premium refrigerators in Compton homes across the 90220, 90221 and 90222 ZIP codes. Our base in Carson is about 6 miles south, so Compton is a short drive for our technicians. We work mainly on Sub-Zero built-in, column and undercounter units. We also repair Viking and Thermador refrigerators, and we service the Wolf ranges and ovens that often share the same kitchen. We are an independent repair company, not affiliated with or endorsed by any of these brands. This page covers refrigerator problems specifically: what we see most often, how a visit works, and what you can check before you call.
Refrigerator problems we see in Compton homes
Most calls start with one of a few symptoms. The fresh food section runs warm while the freezer seems fine. The unit runs constantly. Water pools under the crisper drawers. Frost builds up on the back wall. The ice maker stops producing. Each symptom has several possible causes, and guessing usually costs more than diagnosing.
Summer heat adds to the load. Compton sits inland from the coast, and inland Los Angeles neighborhoods run noticeably hotter in summer than beach areas. Fall Santa Ana winds can bring hot, dry spells on top of that. A built-in refrigerator pulls air through a grille at the top or bottom. When the kitchen is warm and the condenser is coated in dust, the compressor works harder and longer. Weak parts often fail during these stretches.
- Warm fresh food section with a cold freezer, often an evaporator fan or defrost problem
- Compressor running nonstop, which can point to a dirty condenser, low refrigerant or a failing sealed-system part
- Water on the floor or under the drawers, usually a clogged or frozen drain line
- Ice maker not filling, which may be the water valve, filter, supply line or the ice maker module
- Doors that don't seal, caused by worn gaskets or hinges that have shifted out of adjustment
- Clicking, buzzing or rattling from the top grille or the back of the unit

How a refrigerator repair visit works
When you contact us, tell us the brand, the model and serial number if you can find them, and what the refrigerator is doing. On Sub-Zero units the rating tag is usually inside the fresh food compartment near the top, or behind the top grille. With that information, the technician can bring the parts most likely to be needed.
At your home, the technician checks temperatures, airflow, fans, defrost components, controls and the sealed system as needed. We tell you what failed and why, and what the repair involves before any work starts. Many repairs, such as fans, gaskets, valves, thermistors and drain lines, can be finished in one visit. Sealed-system work or a part that has to be ordered may take a second trip. We'll say so up front.
Sub-Zero, Viking and Thermador built-ins
Built-in refrigerators are not the same as freestanding models. Many Sub-Zero units use dual refrigeration, which means separate compressors or separate evaporators for the fresh food and freezer sections. Viking and Thermador column and built-in units have their own control boards, airflow layouts and panel-ready doors. Because these units are fitted into cabinetry, a repair can require sliding the refrigerator out without damaging the flooring or the custom panels. Our technicians are used to that kind of work and handle it carefully.

What to check before you call
A few quick checks can save time or solve the problem outright. If they don't help, they still give us useful information when you call.
- Confirm the unit has power and the control panel isn't in showroom, Sabbath or off mode
- Check that nothing is blocking the vents inside the compartments
- Look at the top or bottom grille and see whether the condenser is covered in dust
- Make sure the doors close fully and nothing is propping a drawer open
- Move perishables to a cooler with ice if the fresh food section is above about 40°F
