If your freezer is cold but the fridge is warm, the sealed system is fine. Check the air damper at the top of the fridge compartment first. A stuck damper blocks cold air from reaching the fridge side and is the most common cause of this symptom.
Freezer's cold but fridge is warm? Here's the good news: your compressor's fine, your refrigerant's fine, the expensive stuff is still working. Something's just blocking cold air from getting to the fridge side. Ignore this and everything in your fridge is gone within a few hours. I've seen this be a $35 damper fix or a $12 defrost thermostat. Don't panic yet, but don't wait either.

Fridge Not Running But Freezer Works
OK so here's the deal. Your fridge and freezer don't actually have separate cooling systems. The freezer gets cold first, then a motorized flap called a damper opens up to let cold air flow into the fridge side. When the fridge is warm but the freezer's perfectly fine, that's actually useful information. It tells you the compressor, the condenser coils, and the evaporator are all doing their jobs. The problem's in delivery, not production. Usually this is a $35-65 fix if it's the damper, or a defrost issue if you've got ice buildup. Way less scary than it sounds.

Symptoms You May Notice
Fridge is 60-70F inside, your food's warm, but when you open the freezer it's still rock solid at 0F or below.
Put your hand over the air vent at the top back of the fridge interior and you feel nothing. No airflow at all.
Thick frost or ice visible right around that vent opening where the cold air's supposed to come through from the freezer side.
Food's been going bad faster than usual for a week or two before things completely stopped cooling down. That slow decline usually means defrost failure building up.
Fridge walls feel room temperature to the touch after it's been plugged in all night.
Can you reset a Generic refrigerator to clear the SYMPTOM code?
Pull the plug from the wall and leave it unplugged for at least 5 minutes, not just 30 seconds. Set both the freezer and fridge controls to the middle setting before you plug it back in. After it's running again, give it 24 hours before you decide if it's working. The fridge compartment takes longer to come down to temp than the freezer does. If it's still warm after 24 hours, start at step 1 with the damper check.

Frequently Asked Questions
Is this different from the fridge just not being cold enough?
Yeah, big difference. A fridge that's running slightly warm, like 45-50F, is usually dirty condenser coils, a bad door gasket letting warm air in, or a temp setting issue. Those are easy fixes. But when the fridge is near room temperature and the freezer's doing perfectly fine, you've got a delivery problem, not a production problem. The cold is being made, it's just not getting to the fridge side. That points you directly at the damper, the evaporator fan, or ice blocking the duct between them.
Can I fix a stuck damper myself?
Honestly, yes, and it's one of the easier fridge repairs out there. The damper assembly sits at the top of the fresh food section behind a plastic cover, held in with 2-4 Phillips screws. Disconnect the wire harness, swap in the new one, done. I replaced three of these last month for customers who'd been quoted $300 in labor elsewhere. The part itself is $30-65 depending on your brand. Search your model number plus 'air damper assembly' and you'll find the exact replacement. Takes about 20 minutes if you've never done it before.
How long can food stay safe in a warm fridge?
Two hours above 40F is the FDA's cutoff for perishable food. That's not a lot of time, especially if this happened overnight and you're just noticing it now. If you're not sure how long the fridge has been warm, smell everything and when in doubt throw it out. Meat, dairy, eggs, cooked leftovers all go bad fast. Move what you can to the freezer or a cooler with ice while you troubleshoot. Don't lose time trying to save $20 in groceries when food poisoning is on the table.
How do I know if it's the damper versus the evaporator fan?
Good question, and it's easy to figure out. With the damper, you can manually push it open with your finger and check if there's cold air coming through. If you push it open and cold air rushes in, the fan's working fine and the damper's your problem. If you push it open and feel nothing, do the door switch test in step 2: hold the freezer door switch in and listen for the fan. Fan's dead quiet? That's your motor. Fan's running but no cold air at the vent? Probably ice blocking the duct. Start with step 1 and work down in order.
My fridge is 10+ years old. Is it worth fixing or should I just buy a new one?
Depends on what's broken. A damper is $35-65 in parts. An evaporator fan motor is $25-60. A defrost heater kit is $20-40. None of those are reason to scrap a working fridge. Where it gets complicated is if the control board is bad, those run $100-250 and sometimes more. If it's an older unit and the board is gone, you're looking at half the cost of a basic new fridge in parts alone. That's when you do the math. But honestly, most of the time this symptom is a cheap fix. Don't assume the worst before you've diagnosed it.
