Amana Refrigerator Running Constantly: Causes

Why won't my Amana refrigerator stop running?#

Is it actually a problem?#

A refrigerator compressor is meant to switch off once the box is cold enough and switch back on as it warms — cycling through the day. Running much of the time isn't unusual, especially in a warm kitchen, but running flat-out without ever pausing while the food still isn't cold enough is the real symptom. Amana models this shows up on include the ART318FFDS, ASI2575GRS, ABB1921BRW, and ART106TFDS.

Work through the causes in this order#

Coils and gasket — the cheap wins. Buried condenser coils are the number-one culprit: caked with dust, they can't release the heat the compressor is pumping, so it never gets to rest. They sit underneath behind the kick plate or on the back — vacuum and brush them, then repeat every 6 to 12 months. Next, check the door seal by shutting the door on a dollar bill; if it pulls out with no drag, the gasket has hardened and warm air is streaming in.

Thermostat, defrost, and refrigerant — the deeper faults. A thermostat stuck reading "warm" never tells the compressor to stop, so turn the dial to its warmest and if the compressor keeps going, it has failed. A dead defrost system lets frost pile onto the evaporator until airflow chokes and the compressor runs to cool through the ice — a 24-hour unplug clears it briefly, but it returns. And a slow refrigerant leak starves the system of cooling capacity, so the compressor runs endlessly without ever hitting target; that's sealed-system work for a certified technician.

Check it yourself#

1. Brush and vacuum the condenser coils — the free fix that resolves the most cases.
2. Dollar-bill test the gasket around the whole door.
3. Set the thermostat to its warmest and watch whether the compressor shuts off.
4. Inspect the evaporator for heavy frost that points to a defrost fault.
5. Non-stop running with a warm box means a sealed-system check.

Repair or replace?#

Because the two leading causes cost little or nothing and Amana's Whirlpool-shared parts are inexpensive, a constantly running unit is nearly always worth repairing — and worth doing soon, since endless running can double or triple the fridge's yearly electricity draw and wears the compressor. A refrigerant leak or a failing compressor is the only call that leans toward replacement, and a diagnostic visit settles it.

Frequently asked questions#

Why does my Amana refrigerator run without stopping?#

Start with the condenser coils — if they're caked with dust, clean them with a brush and vacuum, since that's the most common and cheapest fix. A worn door gasket letting warm air in is next; if both are fine, look to the thermostat or the defrost system.

Does a constantly running Amana cost much more to run?#

Yes — a normally cycling fridge uses about 100 to 400 kWh a year, and a compressor that never rests can push that toward 300 to 1200 kWh. The extra wear on the compressor is the bigger long-term cost, so it pays to fix it promptly.

Should I worry about an Amana that runs all the time?#

It isn't an immediate hazard, but it shortens compressor life and raises your energy bill, and you'll feel extra heat at the back or bottom of the unit. Tracking down the cause — usually the coils or gasket — protects the compressor.
