Amana Freezer Running Constantly: Causes & Fix

Why does my Amana freezer run constantly?#

Normal versus a real fault#

Amana freezers run on the Whirlpool platform and are meant to cycle on and off, holding the box near 0°F. Running most of the time in summer heat is acceptable; running at a solid 100 percent while never quite reaching temperature is the problem. Because garages swing hot and cold, a freezer parked there earns extra scrutiny — the environment is often the cause.

The most common causes, ranked#

Coils and gasket (start here): rear- or bottom-mounted coils clog fast in a garage — vacuum and brush them, and continuous running often eases within a day. Then run the dollar-bill test around the door; a bill that slides out freely means the gasket has hardened and lost its grip.

Thermostat, refrigerant, and ambient: drop a standalone thermometer inside — if it reads 0°F but the compressor still runs, the thermostat is misreading. A freezer stuck at 15 to 25°F with continuous running suggests a slow refrigerant leak, which is sealed-system work. And if the space itself is above about 95°F, the compressor is simply working against the heat, not failing — Amana freezers are rated for a 55 to 110°F ambient.

Check it yourself#

1. Vacuum and brush the condenser coils, front-bottom or rear.
2. Dollar-bill test the door gasket at several points.
3. Set a standalone thermometer inside and compare it to the dial setting.
4. Note the room temperature — above about 95°F, heavy running is expected.
5. If the box holds well above 0°F with the compressor always on, have the sealed system checked.

Repair or replace?#

Coils, a gasket, or a thermostat are inexpensive fixes, so a constantly running Amana freezer is almost always worth keeping — especially under 8 to 10 years old. Only a refrigerant leak tips toward replacement, since sealed-system repair often isn't cost-effective on a value freezer; a diagnostic visit confirms it first.

Frequently asked questions#

Is it normal for my garage Amana freezer to run all summer?#

Running 80 to 90 percent of the time in hot weather is acceptable, since the compressor is fighting the ambient heat. Running a flat 100 percent without ever cycling off usually means the condenser coils need cleaning, and below about 95°F the compressor should still cycle off regularly.

How do I know if the thermostat is the problem?#

Place a standalone thermometer inside and let it settle. If it reads 0°F but the compressor keeps running anyway, the thermostat is reading warmer than the true temperature and won't send the shut-off signal, so it needs replacing.

My Amana freezer only holds around 20°F and never stops — why?#

A box that settles well above 0°F while the compressor runs non-stop usually points to a slow refrigerant leak that has cut cooling capacity. That's a sealed-system repair for a certified technician, who can confirm the leak before you weigh it against a new unit.
