What is going on
When a refrigerator starts drifting past 40 degrees, the problem rarely announces itself. Milk turns early, produce wilts, and the compressor seems to run without rest. Onyx Appliance Service has spent 24 years inside luxury refrigeration, from Liebherr and Thermador columns to GE Monogram built in units and LG French door models. We know how these machines fail, and we arrive with the instruments and genuine OEM parts to put temperatures back where they belong.
Luxury refrigerators are engineered around tight tolerances. A single weak evaporator fan, a clogged condenser, or a control board misreading its thermistors can push the cabinet warm within hours. Sealed system faults are more serious, and they demand a technician who can read pressures and temperatures correctly rather than guess. Our diagnostic visit is $95, waived with your repair, and we explain exactly what failed and what the fix will cost before any work begins.
We service Los Angeles and Southern California daily from 7am to 7pm, with same day appointments in most areas. Whether the unit is a panel ready column, an undercounter drawer, or a full size French door, the process is the same. Precise diagnosis, genuine parts, and a 3 Year Onyx Warranty in writing.
The usual suspects
What fails inside a luxury refrigerator.
Compressor and start components
The compressor drives the entire cooling cycle, and worn start relays or tired windings leave it clicking, humming, or short cycling. We test amperage and start components, and replace the compressor with a genuine OEM unit when it has truly failed.
Sealed system leaks
Refrigerant escaping through a corroded evaporator or a fatigued joint leaves the system running constantly while temperatures climb. We locate the leak, repair the sealed system, and recharge it to factory specification.
Evaporator fan motors
This fan moves chilled air through the fresh food and freezer sections. When bearings wear or the motor ices over, one compartment warms while the other still freezes. We replace the motor and correct the airflow fault behind it.
Control boards and thermistors
Modern refrigerators from LG, Thermador, and GE Monogram rely on sensors feeding a main board. A drifted thermistor or a failing relay produces erratic temperatures. We test the circuit and replace only the component that failed.
Defrost system failures
A failed defrost heater or thermostat lets frost seal off the evaporator coil until air can no longer pass. We restore the defrost cycle and clear the ice so cooling returns.
Door gaskets and hinges
A hardened or torn gasket bleeds cold air and forces long run times, especially on built in columns from Liebherr and Thermador. We fit genuine gaskets and adjust the doors so they seal as designed.
Every one of these faults can produce the same symptom, a warm cabinet, which is why guesswork gets expensive. A factory trained Onyx technician isolates the true cause with proper instruments, carries genuine OEM parts, and backs the repair with a 3 Year Onyx Warranty in writing.
Why it cannot wait
Every hour raises the temperature.
A refrigerator that has lost cooling is on a countdown. Food safety guidance gives perishables about four hours above 40 degrees, and a full built in column can hold over a thousand dollars in provisions. Waiting also strains a compressor that may still be salvageable. A same day visit protects the food and often the machine itself.

Questions, answered
Before you call.
How much does refrigerator repair cost?
The diagnostic visit is $95, and it is waived when you proceed with the repair. After diagnosis you receive a firm quote covering parts and labor before any work begins, so the decision is always yours.
Can you really come the same day?
In most of Los Angeles and Southern California, yes. We are open daily from 7am to 7pm, and cooling failures are treated as priority calls because food is at stake. Call (747) 777-9728 and we will give you an honest arrival window.
Which refrigerator brands do you repair?
We service all major brands, including Liebherr, Thermador, GE Monogram, Gaggenau, Dacor, JennAir, LG, Samsung, Bosch, KitchenAid, Whirlpool, Frigidaire, Electrolux, and U-Line. Onyx is an independent company with 24 years on luxury appliances, not affiliated with any manufacturer.
Is it worth repairing a built in refrigerator?
Almost always. A quality built in refrigerator was designed for decades of service, and replacement can run well into five figures once cabinetry is involved. Most cooling failures come down to one component, and a proper repair restores the unit for a fraction of replacement cost.
What warranty comes with the repair?
Every repair carries the 3 Year Onyx Warranty covering parts and labor, in writing. If the same fault returns within that period, we make it right at no charge.
