All of a sudden everything inside is slowly warming up. The temperature is turned as low as it can go, and the light comes on when I open the door. What can I do? ===== Answer 1 ===== Here are the most likely causes and what you can check yourself: ==== Check These First (Free/Easy) ==== **Condenser coils are dirty** — On older fridges, dusty coils are the #1 cause of cooling failure. They're usually on the back or underneath. Unplug the fridge, vacuum or brush them off, and plug it back in. **Condenser fan isn't running** — Open the fridge while it's plugged in and listen. You should hear a fan running near the compressor (usually bottom-back). If it's silent or the blade is stuck, the fan motor may need replacing (~$20–50 in parts). **Evaporator fan is blocked or broken** — This fan circulates cold air inside. If you don't feel airflow from the vents inside the fridge, this fan may be dead or the evaporator coils may be frozen solid. **Evaporator coils are frozen over** — If the freezer still gets cold but the fridge section doesn't, the defrost system may have failed. Unplug the fridge for 24–48 hours with the doors open to manually defrost, then plug it back in. If it works again temporarily, you need a new defrost heater, thermostat, or timer (~$20–60 in parts). **Compressor is failing** — If you hear clicking sounds or it's completely silent and the fridge is warm all over, the compressor may be failing. On a 16-year-old fridge, compressor repair (~$300–600) often isn't worth it. ==== Quick Triage ==== * Is the //freezer// still cold? → Points to defrost system or evaporator fan * Is //everything// warm including the freezer? → Points to compressor or condenser fan * Do you hear the compressor humming? → Compressor is running, look elsewhere Given the age of the fridge, if the fix requires a compressor or expensive sealed system repair, replacement is usually the smarter financial move. But a dirty coil cleaning or a $30 fan motor could easily buy you several more years. ===== Question 2 ===== Additional findings: The freezer is very cold, about 0°F. I'm hearing a whirring sound underneath the refrigerator, and there is a lot of dust under it. This is a unit with the refrigerator on top and the freezer on the bottom. ===== Answer 2 ===== These findings narrow it down considerably. ==== Most Likely Culprit: Frozen Evaporator Coils / Failed Defrost System ==== Since the freezer is ice-cold but the fridge section above isn't cooling, and the compressor and condenser fan are clearly running (the whirring sound underneath), the refrigeration system itself is working fine. The problem is that cold air isn't making it up to the fridge compartment. On a bottom-freezer fridge, the evaporator coils sit in the freezer section. A small fan blows cold air from those coils up into the refrigerator above. If the coils are encased in ice due to a defrost system failure, the fan can't move air effectively. ==== Diagnostic Test ==== Unplug the fridge and leave both doors open for **24–48 hours**. Put towels down — it will drip. Then plug it back in. If the fridge section cools normally again, the diagnosis is confirmed: the defrost system has failed. ==== The Defrost System Has Three Parts, Any of Which Could Be Bad ==== * **Defrost heater** — melts ice off the coils on a timed cycle * **Defrost thermostat/limiter** — safety cutoff for the heater * **Defrost timer or control board** — tells the system when to run These parts typically run **$15–60 each**, and on a bottom-freezer Maytag they're generally accessible by removing the freezer's back panel. A repair person would charge approximately $150–250 total. ==== Also Recommended ==== Clean all the dust from the condenser coils while the unit is unplugged. On a bottom-freezer model they're usually behind the front kick plate or at the back near the floor. Dirty coils make the whole system work harder and can accelerate other failures. Given that the underlying mechanics are clearly still working, this is likely a repair worth making.
