Amana Refrigerator Not Cooling: Causes and DIY Fix Guide
If your Amana refrigerator has stopped cooling properly, you are likely dealing with one of three common failure modes: a condenser fan that has seized, a defrost system fault causing ice buildup, or a failed start relay. Each of these issues can be diagnosed and often repaired at home with basic tools and under $60 in parts. This guide provides a mechanism-level breakdown of why cooling fails, a clear operator flow for early checks, and specific diagnostics for the most frequent failure modes. By following these steps systematically, you can identify whether the problem is a simple blockage, a faulty relay, or a sealed-system issue that requires professional help.
Early Triage for an Amana Refrigerator Not Cooling Fix
Begin with these earliest checks to rule out trivial causes. Each step includes a natural checkpoint: if you find a problem here, the fix is often quick and free. If you see an error code on the display during this process, write it down—this information helps technicians diagnose the problem quickly later.
Safety First – Unplug Before Touching Wiring
If you intend to inspect any electrical component, unplug the unit or flip the dedicated breaker. Amana refrigerators store voltage in the start capacitor even after unplugging; wait 60 seconds for discharge before working near the compressor.
Checkpoint 1 – Power and Settings
Ensure the refrigerator is plugged in securely and the outlet is live (test with a lamp). Verify the thermostat is not accidentally set to “Off” or the warmest setting. Look for a vacation mode or “cooling off” switch on some Amana models (e.g., the Amana ADB2530 series); if active, turn it off. Branch here: If the error code appears after this checkpoint, proceed to component checks rather than wasting time on settings. If no code appears and the thermostat seems correct but the fridge still fails to cool, move directly to cleaning the condenser coils.
Checkpoint 2 – Listen for Operating Sounds
Stand near the refrigerator and listen for the compressor hum and the condenser fan running. If the compressor is silent or clicking rapidly, you may have a start relay or overload protector failure. If the compressor runs but you hear no fan, the condenser fan motor is likely stalled—a common early failure that you can detect by sound alone.
Checkpoint 3 – Read the Error Code
Many Amana refrigerators with a digital display show an error code when a component fails. Write down any code you see (e.g., “Er 1”, “Er 5”, “HS”)—this information is critical for quicker diagnosis if you escalate to a technician.
Quick Reset Ordered Action
Disconnect power (or flip the breaker) for exactly 60 seconds, then restore power. This clears transient control-board faults that sometimes mimic a no-cooling condition. Success check: If cooling resumes within 1 hour, you likely had a momentary glitch—but monitor for recurrence. Escalation signal: If the same code returns within 24 hours, the control board or a sensor is failing, not a transient glitch.
Early Diagnostic Pass/Fail Checklist
- [ ] Power cord secure and outlet live? – Fridge lights on, compressor clicks.
- [ ] Thermostat set to “Cool” (not Off)? – Temp dial at mid-range (4–5).
- [ ] No error code on display? – Blank or status OK. Write down any code.
- [ ] Compressor hums within 5 minutes of reset? – Low buzz, slight vibration.
- [ ] Condenser fan spins when compressor runs? – Audible fan noise.
If all five items pass but cooling is still insufficient, proceed to the next section.

Common Failure Modes in an Amana Refrigerator Not Cooling Fix
This section uses a trade-off analysis approach: each failure mode has specific symptoms, detection methods, and repair difficulty. Understanding which mode you are facing saves time and prevents unnecessary part purchases. The following table summarizes the three most frequent failure modes for quick comparison.
| Failure Mode | Typical Symptom | Repair Difficulty | Average Part Cost | DIY Time |
|---|---|---|---|---|
| Condenser fan failure | Compressor runs, no fan noise | Low | $30–60 | 30 min |
| Defrost system fault | Ice on evaporator, poor cooling | Medium | $15–80 | 2–4 hours |
| Start relay failure | Single click then silence | Low | $10–25 | 10 min |
Condenser Fan Failure – The Most Frequent Culprit
Why it happens: The condenser fan pulls air across the condenser coils to release heat. Over time, dust binds the motor bearings, or a failed start capacitor prevents the fan from spinning. This failure mode is especially common in Amana bottom-freezer models (such as the Amana AFD2535DEW) where the fan is exposed to pet hair and floor dust.
Detection: Open the lower back panel (or front grille on some models) while the compressor is running. If the fan blade is stationary or spins slowly, the fan motor or capacitor needs replacement.
Trade-off: Replacing the fan motor costs $30–60 and takes 30 minutes. Ignoring it leads to high head pressure, which can damage the compressor—a $300+ repair. Early detection requires only a visual check.
Unique angle – how to detect it early: Pay attention to the sound of the refrigerator. If you notice the fan stops running intermittently (e.g., after a power cycle) or makes a grinding noise, the motor bearings are starting to fail. Catching this before the fan seizes completely can save you from a compressor burnout.
Defrost System Fault – Ice Buildup on the Evaporator
Mechanism: Amana refrigerators with automatic defrost use a timer or electronic control to heat the evaporator coils periodically. When the defrost heater, thermostat, or control board fails, ice accumulates on the evaporator, blocking airflow and reducing cooling.
Detection: Open the freezer compartment and look for frost covering the back wall or the evaporator coils. If you see a thick layer of ice (more than ¼ inch), the defrost cycle has stalled. Do not chip the ice with a sharp tool—let it thaw naturally after unplugging the unit.
Trend insight: Service data across major brands shows that icemaker harvest faults and humidity-sensor issues together account for roughly 32% of no-cooling calls, with condenser fan problems close behind. For Amana models featuring the VitaFreshPro humidity drawer, a failed sensor can trick the control board into reducing evaporator fan speed, indirectly causing temperature rise. This mechanism is often missed in generic repair guides, yet it explains why some Amana units run constantly but fail to hold temperature.
Start Relay / Overload Protector Failure
How it works: The start relay delivers a jolt of current to the compressor’s start winding; the overload protector shuts off the compressor if it gets too hot. Both parts can fail from age or power surges.
Detection: If the compressor tries to start (you hear a single click) but then goes silent, the relay is likely bad. A multimeter test: the relay should show continuity between the run and start terminals; if open, replace it. The overload protector clicks open when hot—let it cool for 15 minutes and test again.
Trade-off: Replacing the relay costs under $20 and is a 10-minute job. Buying the wrong part (universal vs. OEM) can cause immediate failure—always match the model number suffix (e.g., WPW10203597 for many Amana side-by-side models).
Compressor Seized or Refrigerant Leak – The Red Line
These are sealed-system failures that require a certified technician. Symptoms: compressor hot but not vibrating, or frost only on one side of the evaporator (indicating low refrigerant). If you suspect either, stop DIY attempts to avoid damaging the compressor further.
Step-by-Step DIY Repair for the Amana Refrigerator Not Cooling Fix
Once you have identified the likely failure mode, follow this ordered flow. Each step includes a checkpoint to verify progress.
Step 1 – Clean Condenser Coils
Tools: Vacuum with brush attachment, condenser coil brush, soft cloth.
1. Unplug the refrigerator and pull it away from the wall.
2. Locate the coils – usually behind the lower back panel or behind the front grille.
3. Vacuum dust and pet hair thoroughly. Use the coil brush to loosen stubborn grime.
4. Check the condenser fan blade for obstruction; clean it as well.
5. Plug the unit back in and monitor for 1 hour. Checkpoint: If the temperature drops by 5–10°F within 30 minutes, you are done. If no improvement, proceed to Step 2.
Step 2 – Test and Replace the Start Relay
Tools: Screwdriver, multimeter (ohm setting).
1. Unplug the refrigerator and locate the compressor (lower back). Remove the wire cover.
2. Pull the relay off the compressor pins gently.
3. Measure resistance between the run and start terminals (typically 3–20 ohms). If infinite, replace the relay with an exact OEM equivalent.
4. Install the new relay and reconnect wires.
5. Plug in and listen for the compressor to hum steadily. Checkpoint: Cool air returns within 30 minutes. If the compressor clicks and stops again, the overload protector may be tripped—let it cool and retest. Branch here: If the relay tests fine but the compressor still refuses to start, the compressor itself is likely seized, which means escalation.
Step 3 – Check the Evaporator Fan Motor
In the freezer compartment, remove the rear panel to access the evaporator fan. Spin the blade by hand—it should rotate freely. If it is stiff or noisy, replace the fan motor assembly. Escalation signal: If the fan spins but the frost pattern is uneven (thick on one side, bare on the other), you likely have a defrost issue rather than a fan problem.
Step 4 – Manual Defrost Cycle Test
If ice is present, unplug the unit and let the ice thaw completely (may take 6–12 hours). Then plug back in and check if the defrost heater engages after 8 hours of runtime. If the heater never turns on, replace the defrost thermostat or timer/control board. Checkpoint: After thawing, if cooling returns to normal, the defrost system needs repair. If no improvement, the evaporator coil may be leaking refrigerant.

Also, the broader diy guide on how to fix a refrigerator that wont cool covers overlapping failure modes that can also be applied to Amana units when component-level cross-referencing is needed.
When to Call a Technician
Even with a thorough DIY approach, some failures require professional tools. Here are the signals that you should stop self-repair and call a certified technician:
- Compressor runs continuously but freezer and fridge never reach set temperature – possible refrigerant leak.
- Compressor is hot to the touch but does not vibrate or hum – likely seized or failed start winding.
- You see oil residue near the compressor or evaporator – indicates a refrigerant leak.
- Error code points to a sealed-system fault (e.g., “HS” or “E6” on some Amana models).
- You have already replaced the start relay, condenser fan, and evaporator fan, yet the temperature is still above 50°F in the fresh food section.
In these cases, a technician will use a manifold gauge to check refrigerant pressure, leak-detect with UV dye, and potentially replace the compressor or evaporator. Attempting to solder or recharge the system yourself is dangerous and voids any warranty.
Frequently Asked Questions
Q1: Why does my Amana refrigerator stop cooling after a power outage?
Power outages can sometimes corrupt the control board’s memory. Performing a full reset (unplug for 60 seconds) often restores normal operation. If the problem recurs, the control board may need replacement, especially on Amana models with electronic controls from the mid-2010s.
Q2: Can a dirty condenser coil cause permanent damage?
Yes—when condenser coils are blocked, the compressor runs hotter and draws more current, leading to premature wear or thermal shutdown. Regular cleaning every 6 months prevents this and also reduces energy consumption by up to 35%.
Q3: How do I know if the start relay is bad on my Amana refrigerator?
If you hear a single click from the compressor area when the fridge tries to start, then silence, the relay is likely defective. Use a multimeter to confirm—the relay should show continuity between the common and run pins (typically under 20 ohms). If it reads infinite, replace it with an OEM part specific to your model number.
Q4: What does error code “Er 5” mean on my Amana refrigerator?
On many Amana models, “Er 5” indicates a thermistor failure in the fresh food section. Replace the thermistor (part number WPW10235554 or equivalent) located behind the air tower in the refrigerator compartment. After replacement, the code should clear after one cooling cycle.
Monitor your refrigerator’s performance over the next 24 hours after any repair. If the temperature stays between 34–40°F in the fresh food section and between 0–5°F in the freezer, the fix was successful. If you see a return of the original symptoms, revisit the diagnosis—sometimes two components fail together, and catching both prevents a repeat breakdown. Apply the systematic method from this guide to isolate the cause, balance repair cost against risk, and know exactly when to call a professional.
