Refrigerator Not Cooling? Causes, Costs and What to Check First

A refrigerator that stops cooling is the single most common call we take. Across 2,683 visits logged for this exact complaint, the repair that followed had a median cost of 378 dollars, and the middle half of jobs landed between 283 and 490 dollars. The one repair that changes that arithmetic is a compressor replacement, which runs a median of 956 dollars and is why the age of the unit matters before you approve anything. Full pricing from real invoices: refrigerator repair cost. See also how a failed door seal causes the same symptom. See also the evaporator fan that feeds cold air to both compartments.

Which part failed is not a guess. It is determined by exactly which compartments are warm, whether the unit is running, and whether there is frost. Find the sentence below that matches what your refrigerator is doing and read that section. Every price here includes the part, the labor and the service call together. If the cabinet is cold but the ice has stopped, that is a separate job: ice maker repair.

Match Your Symptom to the Likely Cause

The Fridge Is Warm but the Freezer Still Works

This is the most frequent version of the complaint and the most misread. People assume the refrigerator has two cooling systems and one of them died. Almost every household refrigerator has one evaporator coil, located in the freezer, and a fan that pushes that cold air through a duct into the fresh food compartment. The freezer stays cold because it sits next to the coil. The fridge goes warm because the air is not being moved.

That leaves two candidates. The evaporator fan motor has failed, or the coil behind the freezer panel is buried in frost and the fan can no longer pull air through it. Evaporator and condenser fan motor replacement runs a median of 422 dollars across 130 completed jobs.

You can often tell them apart by ear. Open the freezer and listen with the door switch held in. A working evaporator fan is audible. Silence with a cold freezer points to the fan. A fan you can hear straining or clicking against ice points to frost on the coil, which takes you to the defrost circuit rather than the fan itself.

Both the Fridge and the Freezer Are Warm

When neither compartment holds temperature, the fault is upstream of the air distribution and sits in the cooling system itself. The first thing to establish is whether the unit is running.

Stand at the back of the refrigerator. A compressor under load hums steadily and is warm to the touch. Silence, or a cycle of clicking every few minutes followed by silence, is the classic signature of a start relay that has failed or a compressor that will not start. The relay is the cheaper of the two by a wide margin and is always tested first, at a median of 389 dollars across 24 jobs.

If the compressor itself has failed, the repair runs a median of 956 dollars with the middle half between 670 and 1,330 dollars. On built-in and premium units it runs higher still. This is the point where the age of the refrigerator decides the answer, and we say so before the part is ordered rather than after.

The Refrigerator Runs Constantly but Never Gets Cold

A unit that never shuts off is working and failing at the same time, which narrows things considerably. The compressor is turning, so it is not a relay or a dead motor. What is missing is the ability to move heat out of the cabinet.

The cheapest cause is a condenser coil packed with dust and pet hair, common in homes with animals and in units that sit in a garage or a tight cabinet. The coil cannot shed heat, so the compressor runs endlessly and the cabinet never reaches setpoint. Condenser work runs a median of 406 dollars across 29 jobs, and a portion of those visits resolved with cleaning and airflow correction rather than a part.

The more serious cause is a sealed system that has lost refrigerant. That is a different class of repair, it requires recovery and recharge equipment, and on an older unit it is frequently the point where replacement is the better decision.

The Freezer Is Warm but the Fridge Is Fine

The reverse pattern is less common and points somewhere different. Since the evaporator lives in the freezer, a warm freezer with a cold fresh food compartment usually means the control is being told the wrong temperature, or the damper that meters air between compartments is stuck open and dumping the cold into the fridge side.

Thermistor and temperature sensor replacement runs a median of 386 dollars across 65 jobs. A sensor reading a few degrees off does not fail loudly. It quietly instructs the control to stop cooling early, and the symptom looks like a refrigerator that simply is not as cold as it used to be.

Cooling Comes and Goes

Intermittent cooling is a defrost story almost every time. The automatic defrost cycle melts frost off the evaporator coil several times a day. When the defrost heater, timer or thermostat fails, frost accumulates over hours, airflow closes down, cooling degrades, and then a manual defrost or a door left open resets the situation temporarily.

This is why customers report that unplugging the refrigerator overnight fixed it, and that the problem returned within a week. The overnight thaw cleared the coil. Nothing was repaired. Defrost heater and timer replacement runs a median of 395 dollars across 58 jobs.

Frost on the Back Wall with Poor Cooling

A visible sheet of ice on the rear freezer panel is the same fault as the section above, caught at a later stage. We logged 691 visits where frost buildup was the reported problem, and in 369 of those the defrost system was the part replaced, at a median of 368 dollars.

Replacing a fan or adjusting the thermostat while that frost is present will not hold. The coil has to be cleared and the reason it stopped self-clearing has to be corrected. Our page on freezer frost buildup covers this failure in more detail.

One Side of a Side-by-Side Is Warm

Side-by-side and French-door models still share a single evaporator, so the diagnosis follows the same logic. What differs is the duct layout. These designs run longer air paths and more damper hardware, which gives frost and stuck dampers more places to cause trouble, and makes the fresh food side the first to suffer.

It Stopped Cooling After a Power Outage

A refrigerator that was fine before the lights flickered and dead afterwards points at the electronics rather than the mechanicals. Control boards take the brunt of a surge or a brownout, and the failure can be total or partial, where the display works but the compressor never receives its start command.

Control board replacement runs a median of 564 dollars across 78 jobs, which makes it the second most expensive routine repair on a refrigerator after the compressor. Before condemning a board, a technician confirms the relay and the sensors, because both produce overlapping symptoms at a fraction of the cost.

The Fridge Cools Better When It Is Half Empty

If cooling improves when the refrigerator is less full, the problem is airflow rather than cooling capacity. Blocked rear vents, a crisper drawer pushed hard against the back wall or bags stacked over the duct all produce a warm fresh food compartment with a perfectly healthy cooling system.

It is worth ruling this out before a service call, because it costs nothing. Correct temperature settings matter here too, and our guide on ideal refrigerator and freezer temperature sets out the right numbers by model type.

What Causes a Refrigerator to Stop Cooling

Summarised across the 1,421 completed repairs behind this page, the causes fall into four groups. Airflow failures, meaning the evaporator fan or a frosted coil, are the largest single group. Defrost circuit failures come next and often present as an airflow problem. Control and sensor failures form the third group, where the hardware is fine but is being told to stop. Sealed system failures, including the compressor, are the smallest group and the most expensive.

The distribution matters because it tells you what to expect. Most refrigerators that stop cooling need a repair in the 380 to 560 dollar band. A minority need a compressor, and that is a different conversation.

What Each Repair Actually Costs

These are medians from our completed work orders. Each figure includes the part, the labor and the service call together. Quotes that list only the part understate what you pay by two to three times, because on a small-part repair the visit and the labor are the larger share.

Medians from completed Bozmanfix refrigerator work orders. The overall median for a refrigerator repair is 395 dollars, with the middle half of jobs between 319 and 507 dollars. For visits logged specifically as not cooling, the median repair was 378 dollars across 1,421 repairs. Compressor jobs range from 670 to 1,330 dollars in the middle half, and higher on built-in and premium units.

Which Brands We See Most for This Fault

Across the 2,683 visits logged for a refrigerator not cooling, the brand split was as follows. This reflects how many of each brand are installed in the homes we serve, not brand reliability. A brand appearing often here can simply mean it is common in the market.

One brand-specific pattern is worth knowing. LG linear compressor failures have their own history and their own class action record, covered on our LG linear compressor page. For the wider picture of what we service, see our appliance repair statistics.

Repair or Replace

For every repair on the list except the compressor, repair is straightforward arithmetic. A 386 to 564 dollar fix on a refrigerator that cost well over a thousand is not a close call, and the rest of the appliance is untouched.

The compressor changes it. At a median of 956 dollars, the repair approaches a meaningful share of a mid-range replacement, and it signals that the sealed system has reached the end of its service life. On a unit under eight years old, particularly a built-in where replacement means cabinetry work, repair usually still wins. Past twelve years on a standard freestanding model, replacement generally does.
