Amana Refrigerator Not Cooling: Causes and DIY Fix Guide

The most common reason an Amana refrigerator stops cooling is a failed condenser fan motor, not a dead compressor. That fan sits behind the lower back panel, pulls air across the hot coils, and when it stops spinning, the fridge can’t shed heat. The compressor runs, but cooling never happens. This counter-intuitive failure is often overlooked in generic guides, but it’s a frequent culprit in Amana models. Below is a diagnostic flow that prioritizes the most likely causes first, so you don’t swap parts unnecessarily.

First Check: Is the Compressor Running but the Fridge Warm?

Open the lower back grille or remove the rear access panel. Listen for a hum from the compressor. If you hear it but the refrigerator interior is warm, the heat rejection cycle is broken. The compressor is pumping refrigerant, but that heat cannot leave the coils. The most likely missing link is the condenser fan.

Symptom → Cause → Check → Fix

• Symptom: Fridge stays at 50–60°F; freezer is slightly cold but not below 20°F.
• Cause: Condenser fan motor seized or failed; sometimes the fan blade is obstructed by debris.
• Check: With power disconnected, manually spin the condenser fan blade. If it doesn’t spin freely or wobbles, the motor bearings are shot. If it spins but won’t run, test for continuity with a multimeter.
• Fix: Replace the condenser fan motor (part number varies by model, typically 5303918196 or 61005781). This is a 30-minute job: unscrew the old motor, disconnect the harness, install the new one, and reassemble.

As noted in Amana’s technical documentation: “Before performing any diagnostic checks, disconnect the refrigerator from the power supply and allow the compressor to cool for at least 10 minutes.” (Whirlpool Corporation, Amana Technical Sheet)

Ordered DIY Checks to Restore Cooling

Follow this order to avoid unnecessary part swaps. Each step includes what to expect and a common mistake. The sequence rules out the quickest fixes first—cleaning and airflow checks—before moving to electrical components.

1. Confirm Power and Thermostat Setpoints

What to do: Verify the fridge is plugged in, the outlet has power (test with a lamp or multimeter), and the thermostat dials are set to 37–40°F for the fridge and 0°F for the freezer.

What to expect: Many “not cooling” calls are just a bumped dial or a tripped GFCI outlet.

Common mistake: Assuming the compressor is dead when the dial was accidentally turned to OFF or warmest.

2. Clean the Condenser Coils

What to do: Pull the fridge away from the wall. Remove the lower front grille or rear access cover. Use a coil cleaning brush or vacuum with a soft bristle to remove dust, pet hair, and lint from the coils.

What to expect: Heavy dust buildup acts like an insulating blanket. After cleaning, the fridge may take 4–8 hours to reach proper temperature.

Common mistake: Cleaning coils while the fridge is still plugged in—risk of electric shock. Always unplug first.

3. Check the Condenser Fan Motor

What to do: Locate the fan behind the lower access panel or near the compressor. Manually rotate the blade; it should spin freely. Then plug the fridge in and listen for the fan spinning.

What to expect: If the fan hums but doesn’t spin, the motor windings may be burned. If it doesn’t hum at all, use a multimeter to test for continuity across the motor terminals.

Common mistake: Replacing the fan motor without also cleaning the coils—restricted airflow can cause the new motor to fail prematurely.

4. Inspect the Evaporator Fan (Inside the Freezer)

What to do: Open the freezer door. Locate the evaporator fan behind the rear panel (usually behind a shroud). Remove the panel, check for ice buildup on the fan blades or around the fan motor. Listen for fan operation when the door is closed (door switch activated).

What to expect: A frozen fan blade means a defrost problem. If the fan motor is silent but the compressor runs, the motor likely needs replacement.

Common mistake: Forcing the frozen fan blade to spin—can damage the motor or snap the blade.

5. Test the Start Relay and Overload Protector

What to do: Locate the start relay (small plastic box) on the side of the compressor. Unplug it, shake it—if it rattles, it’s broken. Use a multimeter to check continuity across the relay coil and overload switch.

What to expect: A failed relay prevents the compressor from starting properly. If the compressor clicks and then stops after 1–2 seconds, the relay is the likely cause.

Common mistake: Replacing the relay without also checking the compressor windings—a shorted compressor can kill a new relay instantly.

6. Examine the Thermostat and Temperature Sensors

What to do: Locate the thermostat bulb (usually clipped to the evaporator coils) and the thermistor (inside the fridge air channel). Use a multimeter to test resistance at room temperature and compare to the service manual values for your specific Amana model.

What to expect: A failed sensor can tell the control board that the fridge is already at temperature, causing the compressor to cycle off prematurely. Resistance readings outside the expected range (e.g., 10k ohms at 77°F for many Amana units) indicate a faulty sensor.

Common mistake: Replacing the sensor without checking the wiring harness for a break or corrosion—an open wire mimics a failed sensor.

When to Stop and Call a Professional

If you’ve gone through the steps above and the fridge still doesn’t cool, or if any of these apply, it’s time to escalate:

• Compressor is hot to the touch and buzzing loudly — likely a seized compressor that requires sealed-system service.
• Refrigerant leak — you find oil residue near the compressor or on the evaporator coils; EPA regulations require a licensed technician.
• Evaporator coils are iced over even after a 24-hour unplugged defrost — indicates a failed defrost heater, thermostat, or control board.
• You don’t feel comfortable working with electrical components — safety first; a service call is cheaper than a fire hazard.

A broader troubleshooting table covering sealed-system failures can be found in common refrigerator problems and solutions.

Before Ordering Parts: 5 Quick Confirmation Checks

Use this list to avoid misdiagnosis or ordering the wrong component:

• [ ] Power at outlet confirmed — plug a lamp or meter into the same outlet.
• [ ] Thermostat dials set correctly — refrigerator at 37°F, freezer at 0°F.
• [ ] Condenser coils clean — no visible dust buildup behind the grille.
• [ ] Condenser fan blade spins freely by hand — no binding or grinding.
• [ ] Evaporator fan runs when freezer door is closed — door switch is pressed.

If all five pass, the issue likely lies deeper in the sealed system or control board. For a structured approach to control board diagnostics and compressor continuity tests, refer to the step by step guide on how to fix your refrigerator.

FAQ

How long does it take for an Amana refrigerator to cool after a repair?
It can take 6–12 hours to stabilize after replacing a fan or cleaning coils, especially if the fridge was warm when you started.

Can a dirty condenser coil cause warm temperatures?
Yes. When coils are caked with dust, the refrigerator cannot reject heat. The compressor will run constantly, but the fridge stays warm.

Will a faulty evaporator fan cause the fridge to be warm but the freezer cold?
No. A bad evaporator fan will cause both sections to become warm because cold air cannot circulate from the freezer to the fridge. The freezer may stay slightly cool but not below 20°F.

Should I unplug the refrigerator to defrost it before diagnosing?
Only if you see heavy ice buildup on the evaporator coils. A full defrost (24 hours, doors open) can confirm whether the issue is a stuck defrost timer or heater.
