Nine times out of ten, this comes down to one thing: frost choking the evaporator coils so cold air never reaches your freezer shelves.
Annoying? Yes. A death sentence for your fridge?
Rarely. Your milk stays cold because the fridge side barely needs any cooling to hold 37 degrees. The freezer demands far more, and any weak link shows up there first.
Below you’ll find every cause worth checking, what LG and Samsung owners deal with specifically, how long your food survives, and honest repair numbers for Atlanta. Read the first two sections before you touch a screwdriver. You might save yourself a service call.
Why Is Your Freezer Not Freezing But the Fridge Is Cold?
Your refrigerator makes cold air in one place: the evaporator coils behind the freezer’s rear panel. A fan blows air over those coils, then splits the airflow between both compartments. When frost buries the coils or the fan dies, the freezer starves first because the freezer needs the bulk of the cold.
The fridge coasts along on scraps for days, sometimes weeks, before you notice anything wrong up top. So a warm freezer next to a cold fridge almost never means the whole system died. Something is blocking or weakening airflow. Start there.
Common Causes of a Freezer Not Freezing But the Fridge Is Cold
The following can be the reasons behind your freezer not freezing up:
Blocked or Overworked Evaporator Fan
Open the freezer door and hold down the door switch with your thumb. Hear a hum? Good. Hear grinding, clicking, or nothing at all? There’s your suspect.
The evaporator fan is the only thing moving cold air off the coils, and ice loves to jam the blades. A dead motor costs $200 to $300 installed. Ice on the blades costs you nothing but a defrost.
Frost Buildup on the Evaporator Coils
Pull the food out and look at the back wall of the freezer. A solid sheet of ice behind or on the panel means your defrost system has quit. Blame the heater, the defrost thermostat, or the control board.
Here’s the trap people fall into: they unplug the fridge for a day, everything melts, cooling comes back, problem solved. Two weeks later, the ice returns. A manual defrost buys time. The broken part still needs swapping.
Dirty Condenser Coils
Nobody cleans these. Be honest, have you ever pulled your fridge away from the wall? Dust and pet hair pile onto the condenser coils underneath, and the compressor runs hot trying to dump heat through a fur blanket.
The freezer feels the strain before the fridge does. Unplug the unit and vacuum the coils twice a year. It costs nothing. Fixes more freezers than most people expect.
Faulty Door Seal or Gasket
Shut the freezer door on a dollar bill. Now pull. If the bill slides out without a fight, warm humid air has been leaking in every hour of every day, and your freezer has been fighting a losing battle. Replacement gaskets run $50 to $150 depending on brand, and most snap or screw in without special tools.
Overpacked Freezer Blocking Airflow
Costco hauls have consequences. Stack frozen pizzas against the rear vents, and you’ve cut off the cold air supply at the source. Aim for 70 to 80 percent full.
A freezer with some mass in it holds temperature better than an empty one, but the vents need breathing room. Two inches of clearance does the job.
Failing Start Relay or Compressor
Stand next to the fridge for five minutes. A click, a pause, another click, then silence on repeat? Your start relay is failing to wake the compressor cheap-ish fix, usually $150 to $250.
Now, if the compressor runs constantly, feels scorching hot, and the freezer still won’t drop below 20 degrees, the compressor itself is worn out inside. At $300 to $650, you have a real repair-or-replace decision on an older unit.
Bad Temperature Sensor or Thermistor
The thermistor is a tiny sensor feeding temperature readings to the control board. When one drifts out of spec, the board thinks the freezer is colder than reality and cuts the cooling cycle short; the tell: a freezer hovering between 15 and 32 degrees while the fridge behaves perfectly. Testing one requires a multimeter and resistance charts. Skip the guesswork and hand this to a tech.
Freezer Not Freezing by Brand: What’s Different?
Let us have a look at different brands:
LG Freezer Not Freezing
LG’s linear compressors from roughly 2014 to 2020 fail young. Owners know. Lawsuits happened. An LG refrigerator freezer not working while the fridge side hangs on is the classic symptom of a dying linear compressor or a sealed system leak. Before you pay anyone a dime, look up your serial number. LG’s 10-year compressor warranty covers the part on many of these units.
Samsung Freezer or Fridge Freezer Not Working
Samsung’s weak spot is defrost, not compression. French door models ice up around the evaporator cover until airflow chokes off. So a Samsung freezer not freezing usually needs a defrost sensor or heater, a cheaper fix than owners fear. One quirk worth knowing: Twin Cooling models run two separate evaporators, which explains a Samsung fridge freezer not working on one side while the other side runs as if nothing happened.
GE Freezer Not Freezing
Two usual suspects with GE: the main control board and the defrost thermostat. Board failures love to follow power surges and storms. Thermostat failures announce themselves with thick frost on the rear freezer panel. A GE freezer not freezing right after an outage? Bet on the board.
Kenmore Freezer Not Freezing
Kenmore never built its own refrigerators. Whirlpool, LG, and others made them, so the fix depends entirely on your model number prefix. Older units carry a mechanical defrost timer, a $30 part behind the kick plate, and a shockingly common reason for a Kenmore freezer not freezing.
Sub-Zero Freezer Not Working
Sub-Zero builds dual compressor systems. Each compartment gets its own. So a Sub-Zero freezer not working beside a perfectly cold fridge points straight at the freezer-side compressor or evaporator. Don’t DIY these. Genuine parts, certified techs, no shortcuts. You paid premium money for the unit; protect the investment.
Is Your Food Safe in a Freezer That Stopped Freezing?
A full freezer holds safe temps for about 48 hours with the door shut. Half full? Closer to 24. Every door opening bleeds cold, so resist the urge to keep checking. Anything still showing ice crystals refreezes safely. Meat, poultry, seafood, or dairy sitting above 40 degrees for more than two hours goes in the trash, no exceptions. Losing $80 of groceries stings less than food poisoning.
What to Fix Yourself and When to Call a Professional?
| Symptom | DIY Fixable? | Estimated Repair Cost |
| Overpacked freezer | Yes | Free |
| Dirty condenser coils | Yes | Free to $20 |
| Damaged door gasket | Yes | $50 to $150 |
| Frost buildup from defrost failure | Partial | $150 to $350 |
| Evaporator fan failure | No | $200 to $300 |
| Bad thermistor or sensor | No | $100 to $250 |
| Failing relay or compressor | No | $150 to $650 |
Draw the line at tools and gases. Anything solved with a vacuum, a screwdriver, or rearranging food belongs to you. Anything touching refrigerant, the sealed system, the compressor, or a multimeter belongs to a licensed tech. Handling refrigerant without EPA certification breaks federal law anyway, so the choice makes itself.
How Much Does Freezer Repair Cost in Atlanta?
Most freezer repair in Atlanta land between $150 and $450. Expect a diagnostic fee of $75 to $120 up front, and any company worth hiring applies the fee toward your repair. Gaskets and relays sit at the bottom of the range. Compressor and sealed system jobs climb toward $400 to $700. My rule of thumb: once the quote crosses half the price of a new unit on a fridge past its tenth birthday, put the money toward replacement.

- A full, closed freezer protects food for roughly 48 hours.
- Compressor, sealed system, and sensor work belong to a licensed tech.
- Budget $150 to $450 for a typical Atlanta freezer repair.
FAQs
Why is my freezer not freezing, but the fridge is still cold?
Because the cold is made in the freezer, the evaporator coils and fan live behind the freezer’s back panel, so frost buildup or a fan failure hits the freezer first while the fridge coasts on leftover cooling for days.
How long will food stay safe in a freezer with no cooling?
Roughly 48 hours if the freezer is full and the door stays shut. Half full, plan on 24. Ice crystals on the food? Safe to refreeze. Perishables above 40 degrees for two hours or more? Trash.
Should you fix a freezer yourself?
Depends on the fault. Clogged vents, dusty coils, and worn gaskets take an afternoon and basic tools. Compressors, sealed systems, defrost heaters, and sensors need training, testing equipment, and in some cases, EPA certification.
Why is my LG or Samsung freezer specifically not freezing?
Different diseases, same symptoms. LG models from 2014 to 2020 kill their linear compressors early, and a 10-year warranty often covers the part. Samsung models ice up their defrost systems, a cheaper fix. Both leave the fridge cold and the freezer warm.
How much does freezer repair cost in Atlanta?
Plan on $150 to $450 for most jobs, plus a $75 to $120 diagnostic fee most companies roll into the final bill. Sealed system and compressor work on high-end units push toward $700.
