Whirlpool Refrigerator

Why both sections warm at once#

Whirlpool refrigerators run a single evaporator in the freezer, and cold air is shared to the fresh-food side through a damper. So a single warm compartment is a distribution fault (damper, evaporator fan, a compartment thermistor), but both warming together means the core cooling itself has failed. The freezer warms first because it is coupled to the failing evaporator, and the fridge follows within hours. This is time-sensitive: fresh food crosses into unsafe territory after about 4 hours above 40°F, while a full freezer holds safe for roughly 24-48 hours and a half-full one far less.

Diagnosing it is mostly about whether the compressor is even running, and if it runs, whether the heat it makes can escape the coils. If the compressor is silent and you hear only a periodic click, the start relay is the prime suspect and the compressor itself is usually fine. If the compressor runs steadily but nothing cools, the heat has nowhere to go — dirty coils, a dead condenser fan, or a frost-blocked evaporator. Sorting those two situations apart on the first pass keeps you from replacing an expensive compressor that was never the problem.

Causes ranked by likelihood#

Check it yourself, in order#

1. Move food to a cooler and keep the doors closed to stretch the safe window while you work.
2. Listen: a click every few minutes with no compressor run points at a failing start relay, not a dead compressor.
3. Pull the refrigerator out and inspect the condenser coils; if they are coated in dust or pet hair, that is very likely your cause.
4. Vacuum the coils clean, then confirm the condenser fan spins when the compressor runs.
5. Check the freezer evaporator for a wall of frost, which indicates a defrost-system fault choking airflow.
6. If the compressor still will not start with a new relay, it may be seized.

Prevent the repeat#

Vacuuming the condenser coils once or twice a year is the single best way to prevent a both-warm failure, especially in a home with pets whose hair mats the coils quickly. Leaving room for airflow around the cabinet and keeping the door seals clean so they close fully also keep the cooling system from overworking in [summer heat](/blog/summer-refrigerator-tips), when a marginal fridge is most likely to tip over into a full warm-up.

Repair or replace?#

Coils, a condenser fan, or a start relay are inexpensive fixes well worth doing. A seized compressor or a failed sealed system on an older refrigerator is where replacement often wins. A technician can tell a cheap fix from a major one in a single visit. Book a diagnosis for an upfront quote.
