Freezer fault
Any way a built-in freezer stops holding the number it is set to — the defrost cycle, the circulating air, a seal, a sensor or the sealed system.
Frost is evidence. Where it sits, and how quickly it returns after you clear it, names the failed part before a panel comes off. Named and repaired by Sub-Zero Repair Experts Los Angeles — (310) 496-3358.

02Before you call
Six things worth looking at first
Two of the six settle a freezer call without anyone driving out. The other four tell you which repair you are looking at, which means the right part is on the van the first time.
The two-minute pass
- 01
Read the set point on the panel, then read a thermometer left inside the box overnight. If the two disagree by more than a couple of degrees, that gap is the fault. a panel that reads colder than the box.
- 02
Shut the door or the drawer on a strip of paper and pull. If it slides out anywhere along the run, warm room air is being fed into the freezer all day. frost around the door edge.
- 03
Look for boxes pressed against the back wall or stacked over a vent. A freezer packed to the liner starves its own return air and goes cold at the bottom only. cold at the bottom, warm at the top.
- 04
Take the machine-compartment grille off and look at the coil behind it. Grey felt across the fins is the single most common reason a valley freezer drifts by four in the afternoon. a freezer stuck in the teens.
- 05
Empty one shelf and look at the rear panel. A smooth sheet of ice over it means the defrost cycle has stopped clearing the coil, and no amount of turning the dial down will help. a sheet of frost on the back wall.
- 06
Think back to the last outage or the last time the breaker was thrown. A freezer that never climbed back to temperature afterwards is a different conversation from one that drifted slowly. a freezer that will not recover after a power cut.
If the freezer is still wrong after all six, the next step needs a meter and a thermometer left in the box overnight. Sub-Zero Repair Experts Los Angeles, (310) 496-3358.
Ran the six and it is still wrong?
Then it is a reading job, not a settings job. Describe what the freezer is doing and you will hear which band it is likely to land in. 8:00 am – 8:00 pm, seven days.
04What it costs
Six bands, and the visit that tells you which one
- Door gasket or seal replacement $300–$620
- Evaporator or condenser fan motor $340–$720
- Defrost heater, thermostat or sensor $270–$610
- Ice maker, water valve or supply line $290–$860
- Electronic control board $420–$990
- Compressor or sealed-system repair $1,400–$3,040
One flat $89 buys the trip out and the whole fault-finding, and it is deducted from the repair the moment you approve the figure. Which band your freezer lands in is decided by the reading, not by the symptom — which is the whole point of doing it that way round.
05Named faults
Say the fault, not the appliance
- Defrost cycle
- A brief rise that repeats on a daily rhythm and clears itself, which is the defrost cycle working rather than failing.
- Air leak at the seal
- Frost gathered at the rim of the opening rather than the rear panel, because the seal is no longer meeting the cabinet.
- Drawer out of flush
- A drawer that stops short of its seal, held off by ice on the runners, a gasket gone hard, or a load standing too tall at the back.
- Blade strike
- A whir that has sharpened into a scrape or a rattle, made by the circulating fan blade catching ice built up in its housing.
- Failure to recover
- A cabinet that restarted with the power, runs, and still never comes back down to the temperature it was holding.
- Drain blockage
- A flat plate of ice under the lowest basket, built up by defrost water that never made it out of the cabinet.
- Frozen drawer
- A drawer welded in place by ice across its seal or its runners, which is an ice problem wearing the disguise of a broken mechanism.
- Door ajar alarm
- The cabinet's own warning that one of its doors or drawers has been left standing open rather than pulled properly shut.
06What we repair
One compartment, worked on properly
Freezer Repair
The freezer column, the freezer half of a built-in side-by-side, and freezer drawers: defrost, frost, drift and calibration.
- A sheet of frost across the panel at the back of the freezer
- Compartment sitting in the teens when the panel is set near zero
- A freezer drawer that will not pull open, or will not shut flush
- Meltwater running down an inside wall and freezing at the floor
Also on the van, while it is at the house
- Refrigerator Repair The fresh-food side of a built-in Sub-Zero: its own evaporator, its own air circuit, its own thermistors.
- Ice Maker Repair Clear-ice modules, inlet valves, pumps and drains — the stand-alone machines and the ice maker inside a freezer.
- Wine Cooler Repair Zone temperature, door seals and compressor work on Sub-Zero wine storage and beverage columns.
07The route
Two clusters, one pass between them
The territory stays small on purpose: a short route is what makes coming back tomorrow with the right freezer part possible at all.
- 01 Silver Lake90026 Hillside houses from the 1920s with built-ins wedged into original openings, which is why a freezer column here is usually worked on where it stands.
- 02 Los Feliz90027 Spanish and Mediterranean kitchens under Griffith Park, mostly panel-ready columns with the freezer hidden behind a cabinet front.
- 03 Studio City91604 Opened-up ranch kitchens south of Ventura, plus poolside bars where a freezer spends every July fighting the afternoon.
- 04 Sherman Oaks91403 Postwar ranches and hillside remodels off Ventura, usually with a freezer column indoors and a second cold cabinet at a bar.
- 05 Atwater Village Flat blocks between the river and the hill, where a freezer drawer under the counter is as common as a full column.
- 06 Echo Park Steep streets and stair-access houses where a freezer column is worked on in its opening, because getting it out is the expensive part.
- 07 Valley Village Ranch houses north of Ventura, with a second freezer out in the garage taking the full weight of a valley summer.

What people said once the kitchen was back together
Built-in Sub-Zero calls on both sides of the pass.

Panel-ready column hidden behind cabinet fronts, so I expected damage getting it out. A failing thermistor was short cycling the compressor. Swapped, tested, and the panels went back exactly as the installer left them.
Tamsin V.Los Feliz
Cubes came out cloudy and welded into one lump. The inlet valve was barely opening and the filter had not been touched since our remodel. Both replaced, line flushed, and the ice is clean.
Desmond C.Silver Lake
Everything in the freezer went soft over one weekend and I had no idea why. The vents were choked with the fine dust that blows down off Griffith Park, and the defrost thermostat had quit as well. Near zero again by evening.

09Questions
What gets asked on a freezer call
My freezer is at 14°F and will not go lower. What is that usually?
Three things, in this order: a condenser coil matted with dust, an evaporator fan turning too slowly to move real air, or a sensor telling the control a lie. All three let the box get cold and none of them lets it get cold enough, which is exactly why it parks in the teens.
The panel says 0°F but the ice cream is soft. Which one is right?
The ice cream. A panel reports what its sensor reads, and a sensor that has drifted reports a number the compartment never reached. A thermometer left inside overnight settles it, and correcting that gap is calibration work rather than a part swap.
What does the $89 cover on a freezer call?
The trip and the whole diagnosis: a logged temperature against the set point, meter readings on the evaporator fan, the defrost heater and each sensor, the drain checked for ice, and gauges on the sealed system where that is genuinely the question. You get one figure afterwards.
Is frost on the back wall something I can fix myself?
You can clear it, and it will come back. A sheet of ice over the rear panel means the defrost cycle has stopped doing its job, so the ice returns within a week or two. Emptying and thawing the freezer buys time; it does not repair the heater, the sensor or the control behind it.
Do you work on freezer drawers as well as full columns?
Yes, and drawers are a good part of this. A drawer that drags on ice, will not shut flush or has frozen to its rails is a different repair from a column fault, and it is usually a seal, a rail or a drain rather than anything in the refrigeration circuit.

Read the fault before you pay anyone to look at it
Poolside and Garage Freezers Through a Valley Summer
A freezer in a garage or at a poolside bar spends the summer rejecting heat into a room hotter than the kitchen. What that costs it, and what keeps it working — Sub-Zero Repair Experts Los Angeles, (310) 496-3358.
How a Sub-Zero Defrost Cycle Works, Part by Part
A freezer clears its own coil on a cycle: an element melts the frost, a sensing part ends the run, a trough carries the water out. Where that cycle breaks decides the repair — Sub-Zero Repair Experts Los Angeles, (310) 496-3358.
Repair It In Place or Carry It Down the Steps: Built-In Refrigeration on Silver Lake and Los Feliz Hillside Streets
On a Substandard Hillside Limited Street the question is not what failed but whether the built-in can be repaired where it stands: getting it down a narrow Silver Lake or Los Feliz roadway, or a public stairway, often costs more than the fault. Sub-Zero Repair Experts Los Angeles, (310) 496-3358.
