If your freezer is freezing but the fridge is warm, the problem is almost always a lack of airflow. I usually look for a failed evaporator fan or a defrost system that has allowed ice to clog the air passages.
Nine times out of ten, there's a thick wall of ice hiding behind your freezer panel that's strangling the airflow. When the defrost heater quits, the evaporator coils turn into a solid block and the fan can't push cold air into the fridge. It's rarely a refrigerant problem since the freezer's still freezing fine. Fan, defrost circuit, and air damper. That's where I start every single time.
Most people panic and think they need a new compressor. They don't. Your fridge is warm because cold air is trapped in the freezer side and can't get through. Could be a stuck damper, a dead fan motor, or a heater that's been out for weeks letting ice pile up. Usually a $30-60 part fixes this whole thing, which is way better than the $1,500 someone probably quoted you for a new fridge.

Symptoms You May Notice
Your fridge feels like room temperature or warmer, but the freezer is still making ice just fine.
Food in the fridge spoils way faster than it should. Milk going bad in 2-3 days is a classic sign.
There's a thick wall of solid ice covering the back panel inside the freezer, like a glacier back there, when you pull the shelves and look.
You can hear the freezer running but there's zero air movement coming through the vents into the fridge compartment.
The fan is making a grinding or chirping noise from the back of the freezer, or you hear absolutely nothing from back there.
Can you reset a Maytag refrigerator to clear the FRZ-COLD-REF-WARM code?
Unplug the refrigerator from the wall outlet. Wait a full 5 minutes, not just 30 seconds. Plug it back in and give it 24 hours to stabilize before you decide whether it worked. If you just cleared a bunch of ice buildup, run it mostly empty for the first few hours. If the fridge is warm again within a week, a reset isn't your fix and a defrost component needs replacing.

Frequently Asked Questions
Can I just unplug the Maytag for 24 hours to fix this?
Honestly, yeah, that'll fix it temporarily. Unplug it, pull everything out, let it thaw for 24-48 hours with the doors open, then plug it back in. It'll probably work great for the next 3-7 days. But if your defrost heater or bimetal thermostat is actually dead, the ice comes right back. I get calls the following week from people saying it worked but now it's warm again. That's your sign to actually fix the defrost system. The thaw-and-hope approach works if the cause was a one-time thing like a long power outage. For a failed component, you're just delaying the inevitable.
Why is my freezer still cold if the fridge is warm?
Because the cooling coils are only in the freezer. Your fridge doesn't have its own cooling system. It borrows cold air from the freezer through a duct and a fan. The freezer stays cold because that's where the refrigerant actually evaporates and absorbs heat. The fridge is downstream of all that. So if the air path gets blocked with ice, or the fan dies, the freezer keeps doing its thing but the fridge gets nothing. Think of it like a furnace that's working perfectly but a closed vent means one room stays cold. The source is fine, the distribution is broken.
How do I know if the evaporator fan is bad?
Press the door switch on the freezer door frame and listen. You should hear a fan clearly. If there's silence, or you hear grinding and chirping, the fan's either dead or the blade's frozen against the housing. Also put your hand near the vents inside the fridge. Zero airflow is a dead giveaway. I replaced three of these fan motors last week alone on Maytag French doors. The part usually runs $25-45 and it's pretty straightforward to swap out once you've got that back panel off. Takes about 30-40 minutes if you haven't done it before.
Is a warm fridge always a defrost problem?
Not always, but I'd say 70-80% of the time when the freezer's cold and fridge is warm, it's the defrost system failing. The other common one is a stuck damper, which is maybe 15% of cases. Fan motor is next. Control board is actually pretty rare for just this symptom. I always start with defrost because you can visually confirm it by pulling the freezer panel and seeing if the coils are encased in ice. That takes 10 minutes and tells you a lot. If the coils are clean, then you start looking at the damper and the fan.
How much does it cost to fix a Maytag defrost issue?
DIY, a defrost heater runs $25-45, bimetal thermostat is $15-30, and a fan motor is $25-50. So you're looking at under $100 for parts on most of this. If you call a tech, expect $150-300 total depending on your area and which part failed. The damper assembly is a bit more, usually $50-80 for the part. All of this is worth fixing on a fridge that's otherwise in decent shape. Way better than dropping $1,200 on a new appliance for a problem that's basically a $40 part and an hour of your time.
How long does it take to fix this myself?
Once you've got the part in hand, most of this is a 30-60 minute job. Pulling the freezer panel takes maybe 20 minutes the first time. Testing with a multimeter is 5 minutes. Swapping the heater or bimetal is straightforward, just disconnect the harness and clip in the new part. The annoying part is if there's a ton of ice built up, because you've got to let it melt before you can get to the components. Put some towels down and either let it thaw naturally for a couple hours or speed it up carefully with a hair dryer on low.
