If the freezer is cold but the fridge is warm, suspect airflow (a fan, damper or iced-over evaporator). If both are warm and you hear nothing running, suspect power, controls or the start components. If both are warm and the compressor runs constantly, suspect dirty coils, a failing condenser fan or the sealed system.
What does it look and sound like?
| Pattern | Likely area | You can try |
|---|---|---|
| Freezer cold, fridge warm | Evaporator fan, air damper, frost on the evaporator | Clear vents; check for frost on the back panel |
| Both warm, compressor silent | Power, control board, start relay, thermostat | Check outlet, breaker and settings |
| Both warm, hot sides, constant running | Dirty condenser coils or failed condenser fan | Clean coils; give the unit clearance |
| Cool, but not cold enough | Door seal, overloaded shelves, ambient heat, thermistor | Check gasket, door closing, location |
| Cools, then warms in cycles | Defrost problem causing repeated frost-ups | Look for frost; note how long between episodes |
The ten-minute triage
- Power and settings.Confirm the fridge is plugged in and the outlet works (try a lamp). Look at the temperature controls: it is easy to bump a dial or switch on a demo or “showroom” mode on touch-panel models.
- Listen.With the fridge quiet, you should hear a compressor hum and a fan inside. Silence from both is different from loud noise with no cooling.
- Open the freezer.Is the freezer actually cold? If yes, the cold air is not reaching the fresh-food side. If no, the whole cooling system is in question.
- Check the vents.Move food away from the air vents inside the fridge and freezer. Overstuffed shelves block the airflow that carries cold air through the cabinet.
- Feel the back wall.A thick coat of frost on the freezer back panel suggests the defrost system has failed.
- Clean the coils.Unplug the unit and vacuum the condenser coils and surrounding area, following the manual. Dust acts like a blanket on the coils.
- Test the door seal.Close a piece of paper in the door at several points. If it pulls out freely anywhere, the gasket is leaking cold air.
Frost on the back wall
A frost-free refrigerator melts frost off its evaporator several times a day through a defrost heater, a sensor and a control. If one of those parts fails, frost builds until it blocks airflow, and the fridge slowly warms. Unplugging the unit with the doors open for about a day (with the food moved to coolers) melts the ice and often brings temperatures back for days or weeks, but that is a temporary reset, not a repair. If frost returns, the cause is still there.
Safe to do
- Unplug, remove food, and let ice melt with towels around the base.
- Use a hair dryer on a low setting, held at a distance, to speed up frost removal.
- Wipe and dry the interior before restarting.
Do not do
- Chip ice with knives, screwdrivers or picks.
- Use a heat gun or open flame.
- Keep restarting a unit that trips a breaker.
Food safety while you wait
USDA guidance is that refrigerated food should be kept at 40°F or below and that perishable items held above 40°F for two hours or more should be discarded. Keep a cheap appliance thermometer in the fridge so you know the actual temperature. If the fridge is failing, move meat, dairy, eggs and leftovers to a cooler with ice or to a neighbor’s fridge while you wait for a visit.
Heat makes everything worse
Austin kitchens in summer, with the oven on and afternoon sun on the window, run hot. A refrigerator in a sun-exposed alcove or a hot garage works close to its design limits. If cooling struggles mainly in the hottest weeks, check the location, leave clearance around the cabinet and make sure the condenser area is clean before assuming a part has failed.
What to tell the technician
- Brand, model and serial number, and approximate age.
- Whether the freezer is cold, and what the thermometer reads in each compartment.
- Any frost, water, odd noise or burning smell, and when each started.
- Recent power outages, surges, moves or electrical work in the house.

Questions people ask
Why is my freezer cold but the fridge warm?
The compressor is probably working, but cold air is not moving into the fresh-food section. A failed evaporator fan, a stuck damper, a blocked air passage or a frost-covered evaporator are the usual causes.
Will unplugging my fridge reset it?
Unplugging for about five minutes can reboot some electronic controls. Leaving it off for a day to melt frost is a different process. Neither fixes a failed part.
How long does food last in a warm refrigerator?
Perishable food above 40°F for two hours or more should be discarded. Use a thermometer rather than feel to decide.
Could it just be the compressor?
Sometimes, but it is one of the less common causes. Dirty coils, a failed fan or a faulty relay are more common and cost less to fix.
Is it worth repairing an older refrigerator that stops cooling?
It depends on the part. A fan, relay or sensor on a unit in good shape usually is. A sealed-system repair on a very old unit often is not. See our repair-or-replace guide.
