Freezer Stuck in the Teens With the Compressor Never Resting
Check these before you call anyone

Take the machine-compartment grille off and look. A coil wearing a grey mat of dust and hair has to be brushed clear before any other reading means anything, and it is the one job an owner can do.
- 02
Log the compartment morning and evening for two days. Drift that widens through the afternoon and closes again overnight is the room driving it, not the cabinet losing its mind.
- 03
Move anything stacked against the rear wall or over a vent. Cold has to leave the coil, cross the compartment and come back; a wall of boxes along that path shows up as degrees.

Listen at the machine-compartment grille with the kitchen quiet. A condenser fan that has stopped turning leaves the coil dumping heat into still air, and the whole cabinet pays for it.
If none of that is it, stop there — the next step needs a meter. Sub-Zero Repair Experts Los Angeles, (310) 496-3358.
Why the valley makes this one seasonal
A freezer does not destroy heat, it relocates it. Everything taken out of the compartment is pushed through the coil in the machine bay and handed to the room, so the room is part of the machine. In Studio City, Sherman Oaks and Valley Village that room runs hot for a long stretch of the year, and a cabinet in a garage or behind a poolside bar has it worse again.
That is why the same freezer that held its number all spring is three or four degrees short by the end of August. Nothing broke on a particular day: the margin it had been running on quietly ran out, and an inefficiency became a symptom.
The order it is worked in
The coil comes first, because a matted condenser imitates every other fault on this list and costs nothing to rule out. Then the fan beside it: heat cannot leave a clean coil either if nothing is moving air across it. Then the fan inside the compartment, which carries the cold the other way and is easy to mistake for the first one from outside.
Only after those three is the sensor worth metering and the charge worth putting gauges on. Working the other way round, gauges first because the symptom sounds like refrigerant, is how a cabinet gets opened for a fault that was a brush and ten minutes.
A compressor running without rest is the tell that runs through all of it. A healthy freezer cycles; one carrying an extra load never gets to stop, and the sound of that is usually the first thing an owner notices before the food ever softens.
If it is not that
When the fan in the machine bay is the part that has given up, the work and the range are onthe condenser fan motor page.
A compartment that never gets properly cold at all, rather than settling a few degrees high, belongs undera freezer that is not freezing.
Summer drift is the commonest call from the ranch kitchens south of the pass, which is why it leadsthe Studio City page.
Follow-ups
Why does this only turn up in late summer?
Because the room joins in. A freezer throws its heat out through a coil into the kitchen or the garage around it, and the warmer that space runs, the harder the same cabinet has to work for the same result. A unit with no margin left in it loses its grip first in September.
Is it worth brushing the coil myself before booking a visit?
Yes, and do it before anything else. The machine-compartment grille comes off by hand, a soft brush and a vacuum clear the fins, and some cabinets recover within a day. If yours is still short a few degrees after that, ring Sub-Zero Repair Experts Los Angeles on (310) 496-3358.
