When your fridge and freezer both stop cooling, the first thing to check is the condenser coils underneath or behind the unit for heavy dust buildup. If the coils are clean and you hear a clicking sound every few minutes, your compressor start relay has likely failed and needs replacement.
In fifteen years of doing this, I've found that total cooling failure is way less scary than it looks. Nine times out of ten it's a start relay or dirty coils, not a dead compressor. But ignore it for even a few hours? You're looking at spoiled food, and a potential compressor burnout that turns a $25 fix into a $700 nightmare. So let's figure this out now.

Fridge Not Cooling or Freezer Warm: Fix It Now
OK here's the deal. Diagnosing a warm fridge is process of elimination, and you always start with the cheap stuff. Most of the time the fix costs under $50. I've literally seen people drop $800 on a compressor when a $25 start relay would've done it. Don't be that person. Work through these steps in order.

Compressor internal failure10%
Symptoms You May Notice
Ice cream is completely soft or liquid even though the freezer still feels slightly cool to the touch.
You hear a click from behind the fridge every 2-3 minutes, then silence, then a click again. No hum, no motor sound following it.
Hold your hand near the bottom vent grille and feel absolutely zero airflow.
There's a solid sheet of ice covering the entire back wall inside the freezer compartment.
The compressor housing on the back of the unit is scorching hot, way hotter than just warm.
Can you reset a Generic refrigerator to clear the NOT-COOLING code?
Unplug the fridge for a full 10 minutes, not just 30 seconds. If your model has a control panel, press and hold the Door Alarm and Freezer Temp buttons together for 5 seconds while it's unplugged to drain any residual power from the board. Plug it back in and don't panic if it takes 4-6 hours before you feel real cooling. Give it a full 24 hours to stabilize before you decide the repair didn't work.

Frequently Asked Questions
Why is my fridge not cooling but the freezer is?
This is an airflow problem almost every time. Your fridge doesn't have its own cooling coils. It borrows cold air from the freezer through a small vent, pushed by the evaporator fan. When that fan dies or ice blocks the vent, the freezer stays cold because it's right next to the evaporator coils, but zero cold air makes it into the fridge section. Check that fan first, then look for ice blocking the air duct between the two compartments.
How do I know if my compressor is bad?
Honestly? You usually don't know until you've ruled out everything cheaper. A bad compressor either makes a loud knocking thud when it tries to start, or it's completely silent while getting insanely hot to the touch. The real test: replace the start relay first, it's $25. If the compressor still won't hum after that, then yeah, it's probably the compressor internally. At that point you're looking at $600-900 for a repair, so get a quote and compare it to the cost of a new fridge before you commit.
Can a dirty coil cause the freezer to stop freezing?
Yes, and it happens faster than you'd think. When the coils can't release heat, the refrigerant stays too warm to absorb heat from inside the cabinet. The compressor keeps trying but overheats, and the thermal overload trips it off. Now nothing's running at all. I've seen this happen after just one year of not cleaning if there's a dog or cat in the house. Clean those coils every 6 months if you've got pets, once a year minimum otherwise.
Is it worth fixing a 10-year-old fridge that isn't cooling?
Depends completely on the fix. Start relay or fan motor? Do it, absolutely. We're talking $30-150 in parts and maybe an hour of your time. Compressor? That's a different conversation. You're looking at $600-900 in parts and labor on an appliance that's already past its halfway point in life. Rule I use personally: if the repair costs more than half what a new unit would cost, buy new. A decent replacement fridge runs $900-1400 these days, so keep that number in your head.
How long does it take a fridge to cool back down after a repair?
Way longer than most people expect, and this is where people freak out and think the repair didn't work. Figure 4-6 hours minimum before it even starts feeling cold, and a full 24 hours to reach stable temperatures. Don't put warm food back in right after the fix. Give it at least 3-4 hours first. You want the freezer hitting around 0°F and the fridge section landing between 35-38°F. Still not there after 24 hours? Then you've either got a second issue or the repair didn't fully solve it.
