For some reason, most Amana refrigerators eventually run into a similar problem of simply not cooling. There are countless cases of Amana refrigerator owners who say they’ve had this problem.
Here’s the good news – after working on used appliances for over a decade now, I can tell you that around 80% of all Amana refrigerators that won’t cool are relatively easy to fix.
If you try each and every one of these solutions, I am extremely confident one of them will work for you. For most of these fixes, you only need a screwdriver!
Amana Refrigerator Not Cooling
If your Amana refrigerator is not cooling, it’s because the condenser coil in the back is dirty and needs to be cleaned. The condenser coil exchanges hot air outside the refrigerator, for cold air inside. If it is obstructed in any way your refrigerator will not cool properly.
But before you start taking your refrigerator apart, I want you to check a few “obvious” things for me.
Unplug refrigerator and check power outlet
First, unplug your refrigerator and try plugging something else into the same outlet. Just make sure that outlet is working. If it’s not, go to your circuit breaker box and see if the circuit is tripped.
If the outlet is working, go ahead and keep your refrigerator unplugged for 2 full minutes before plugging it back in.
This will reset your refrigerator and may just fix your cooling issue.
Oh, and while you’re back there, make sure there is at least 1 inch of clearance between the wall and the back of your refrigerator. This allows for proper ventilation!
Check temperature control settings
Ok next. I know this also sounds incredibly obvious, but just triple check that your temperature control settings are correct.
You wouldn’t believe how many times I “fixed” a Amana refrigerator that wasn’t cooling by simply turning the temperature control settings down.
Sometimes these settings get changed accidentally, or a kid plays with them. But ultimately if the temperature is set too high, your refrigerator simply will not cool properly.
There are several different types of temperature controls depending on the Amana model refrigerator you own. All of them are fairly straightforward to adjust.
Check refrigerator and freezer doors
One last seemingly obvious thing before we jump in.
Make sure that both doors are not obstructed in any way, and that they are able to close fully. Sometimes large containers, or trays can prevent the doors from closing.
While you’re checking this, take a look at the door gaskets that help seal the door, and prevent any air from escaping.
If you see a gasket that appears to be separating from the door, simply use your hand to press it back into place.
Check and clean condenser coils
Ok, now that you’ve confirmed your outlet works, the temperature settings are correct, and that the doors are closing properly, go ahead and unplug your refrigerator and pull it out and away from the wall.
Just keep in mind that you will need to eventually power on the refrigerator again for some of the troubleshooting steps later on!
With your refrigerator unplugged and pulled out, go ahead and check the vent at the back. You want to make sure there are no obvious physical obstructions blocking this vent.
This vent pulls fresh air in to cool down the refrigerator’s condenser system. Over time, it can pull in dust and debris that block the vent altogether. Often, when your refrigerator isn’t cooling, this is the issue.
Now that you’ve cleaned up the vent, go ahead and take off the back vent plate entirely. Remove each screw until it’s fully off.
Removing the vent plate will expose the condenser coil. The condenser coil exchanges heat outside the refrigerator, for cold air inside. If your condenser coil looks anything like the one below, it needs a deep clean!
Obstructed condenser coils cause your refrigerator to not cool properly. You may still get a little bit of cold air, but not much.
To clean the condenser coil, you’ll want to use a condenser brush and a vacuum cleaner. The condenser brush makes the job a lot easier, but if you don’t have one you can try using a brush of a different kind.
Make sure to get all the dust and dirt off the condenser coil, and vacuum up the debris as you go.
Keeping the condenser coil clean will ensure your refrigerator can properly exchange the hot air for cold.
One additional thing to keep in mind: depending on the Amana refrigerator model you own, the condenser coils may be entirely on the back, or they may run to the front of the refrigerator as well (underneath the kick-plate).
If that’s the case, make sure to clean and vacuum out the front as well.
After you’ve cleaned everything up, go ahead and plug your refrigerator back in. Hopefully it’s cooling now!
It’s a good idea to do this type of cleaning every 6 months or so going forward.
Check the condenser fan
If you cleared the vent and cleaned off the condenser coils, and your Amana refrigerator is still not cooling, it’s time to do a bit more investigating.
Let’s start by looking at the condenser fan.
The condenser fan is typically located between the compressor and the condenser coils. Its job is to keep fresh air circulating, cooling off the coils and the compressor.
If this fan stops working, it can have the same effect on your refrigerator as the dirty coils – it will prevent the refrigerator from cooling properly!
Take a good look at this fan and make sure it is clean and running well. If you see damage or extreme rusting, then it needs to be replaced.
When your refrigerator is plugged in, this fan should come on automatically, and stay on at all times. If it doesn’t, this is likely the culprit.
Check the compressor relay
Next, you’ll want to check the compressor relay.
With the refrigerator on, touch and feel the compressor to see if it is running. It has a motor inside the unit that runs to cool the refrigerator.
If you don’t feel any movement, or hear any buzzing of any kind, it’s very likely that the piece to the left, the compressor relay, is broken.
The compressor start relay provides power to the compressor. It determines when the compressor is on, and when it’s off.
To check if it’s broken, unplug your refrigerator and then plug it back in. Listen closely to the compressor. If you hear the compressor “click on”, and then quickly “click off”, it’s likely that you have a bad relay.
Next, go ahead and unplug your refrigerator, and then unplug and remove the relay. Once the relay is off, go ahead and give it a shake.
If you hear a lot of rattling, it’s likely the relay is bad. If small particles fall out as you shake it, it’s definitely bad!
As a final test, you can use a multimeter to check for continuity.
If you don’t get a reading, the contacts have been destroyed and you will need a new relay.
Check the temperature control thermostat
Ok, at this point we’ve checked everything we need to on the back of the fridge. If your Amana refrigerator is not cooling still, it’s time to start investigating the front.
The first thing to check is the temperature control thermostat, which is located in the refrigerator, on the ceiling. This thermostat constantly monitors the temperature of the refrigerator and “signals” to the evaporator when to turn on and off.
Occasionally this thermostat fails, and that could be why your Amana refrigerator is not cooling.
Before you start taking things apart, go ahead and hit the underside of the temperature control housing with your hand. You may need to hit it a few times, but eventually you should hear the refrigerator’s fan motor turn on.
That’s a tell-tale sign that this thermostat is broken and needs to be replaced.
You’ll see several screws on the underside of the housing that need to be removed.
HINT: take before photos of how everything is set up and connected! This way, when you go to put it all back together, you have a reference.
Inside this compartment you’ll see the temperature control thermostat. Fully disconnect it and replace it with a new one.
Check the evaporator(s)
If the temperature control thermostat isn’t the issue, it’s time to start troubleshooting the evaporator system. But first, a quick note on refrigerator evaporators.
Single vs. dual evaporators
Evaporators are what make your refrigerator cold.
Older, more traditional refrigerators, had just one evaporator, located in the freezer.
A fan would then blow the cold air generated in the freezer by the evaporator, into the refrigerator portion of the appliance.
These days, many newer refrigerators have “dual evaporators” – there is one evaporator in the freezer, and a second evaporator in the refrigerator.
In theory, dual evaporators allow for more precise control over the temperature of the freezer and refrigerator environments, respectively.
I mention this because depending on the Amana refrigerator model you own, you may have one, or two evaporators.
Single evaporator Amana refrigerators
If you have a single evaporator, start by making sure your refrigerator is unplugged and then open up the freezer.
Remove all the shelves in your freezer, followed by all the screws that secure the evaporator panel to the back of the freezer. This panel covers up the evaporator coils.
These evaporator coils are responsible for cooling the whole system down.
If you discover a lot of snow/ice build up on the back of the panel and/or on the evaporator coils themselves, you’ll want to inspect the defrost thermostat at the top of the evaporator coils.
Here is a closer view of the defrost thermostat, as it can be a bit hidden on these types of refrigerators!
If the lid of the thermostat is swollen, then your defrost thermostat is bad and needs to be replaced.
If you don’t see anything visually wrong with the thermostat, you can test it for continuity while the thermostat is under 30 degrees. This is pretty tricky to do however, so you’ll probably want to call a technician to help.
Assuming your thermostat is fine, the next thing to check is the defrost heater.
Underneath the evaporator coils, at the bottom of the freezer, you’ll find the defrost heater. The defrost heater turns on every few hours to thaw out the ice that builds up on the coils.
If the defrost heater isn’t working, your coils will turn into a solid block of ice, and stay that way!
For some models of Amana refrigerators, these are especially difficult to test while still attached, so I recommend removing it entirely.
Once it’s removed, use your multimeter set to Ohms resistance (or continuity) and see if you can get an electrical signal.
If it’s working, you should be able to get a signal between 20-40 Ohms.
Dual evaporator Amana refrigerators
For dual evaporator refrigerators, you’re going to want to check the evaporator in the refrigerator, not the freezer, since it’s your refrigerator that isn’t cooling.
Start by making sure your refrigerator is unplugged, and then go ahead and open up the refrigerator door(s).
Remove all the shelves and drawers from your refrigerator, followed by all the screws that secure the evaporator panel to the back of the fridge. This panel covers up the refrigerator evaporator coils.
These evaporator coils are explicitly responsible for cooling down the refrigerator.
Underneath the refrigerator evaporator coils, at the bottom, you’ll find the defrost heater (it’s the difficult to see, black cord running horizontally along the bottom side of the coils in the back).
The defrost heater is designed to turn on every few hours to thaw out the ice that builds up on the coils.
If you discover a lot of snow/ice build up on the back of the panel and/or on the evaporator coils themselves, you’ll want to let everything thaw out.
Sometimes, if the refrigerator door is left open for too long, excess moisture from the air will get pulled in. This causes condensation to build up, resulting in ice on your refrigerator’s coils.
After you let the ice melt, plug your refrigerator back in and see if your refrigerator is able to cool down again.
If it still won’t cool down, it’s possible your defrost heater needs to be replaced, or your evaporator fan isn’t working…
Check the evaporator fan
If you’ve made it this far and your Amana refrigerator is still not cooling, it’s time to check on the evaporator fan.
The evaporator fan controls airflow from the evaporator coils, and then circulates it throughout the refrigerator and/or freezer. If it’s not running, your refrigerator may get chilly, but certainly not cold.
The quickest way to inspect it is to simply listen for it.
Note again that newer Amana refrigerators typically have two evaporator fans: one in the refrigerator, and the other in the freezer. The older, more traditional Amana refrigerators have just one evaporator fan, located in the freezer.
Single evaporator Amana refrigerators
For the older models, on the freezer side, you can remove the light mountings and then look up through the casing to see whether or not the evaporator fan is running.
If you want to get a really good look at the fan, you’ll have to spend a bit more time getting the entire system out. This isn’t complicated, but it does take a bit of patience.
Once you’ve exposed the fan, see if it turns on. If it doesn’t, there are usually two reasons:
- An obstruction (such as ice build up)
- Or the fan has failed
If the fan has failed, check to see if the door switch is helping the fan to start and stop properly. The door switch is pressed in when the door is closed (it also turns the light on and off).
Just press the switch in with your hand to simulate a closed door. The evaporator fan should come on shortly after.
You can also use your multimeter to see if the fan is getting the proper 8-14 Volts of DC power it needs to run. If it’s failing to get the proper voltage, the control board itself may be bad.
Dual evaporator Amana refrigerators
For dual evaporator refrigerators, you’re going to want to check the evaporator fan in the refrigerator, not the freezer, since it’s your refrigerator that isn’t cooling.
To check if the refrigerator evaporator fan is working properly, simply keep the evaporator panel from the refrigerator portion partially off, but still connected (so that you can see the evaporator fan fully).
Then close the refrigerator doors and wait two minutes.
Quickly open the doors after the two minutes are up, and you should catch this fan still moving for a few seconds.
If it isn’t moving, it’s likely that the fan has failed.
Check the defrost drain
By now you know that your refrigerator has evaporator coils that serve to cool down your appliance. And every so often these coils are defrosted to prevent permanent ice build up.
When evaporator coils are defrosted, water is produced.
This water is suppose to drain into your refrigerator’s defrost drain. But occasionally the defrost drain beneath your refrigerator’s evaporator coils get clogged.
When this happens the excess water freezes over during the next “frost cycle”, and the defrost heater is not capable of melting the additional ice.
Somewhat counterintuitively, if your Amana refrigerator is to not cooling properly it is likely caused by all this excess ice.
To fix this issue, I recommend you let your refrigerator thaw out and then force air through the drain to unblock it. It’s possible some debris built up in the drain overtime.
Alternatively, you can use a turkey baster to blast water down the drain.
Single evaporator Amana refrigerators
If you have an older, single evaporator refrigerator, look for the defrost drain in the freezer, just below the evaporator coils.
Dual evaporator Amana refrigerators
In newer, dual evaporator refrigerators, you’ll find the defrost drain in the refrigerator, just below the evaporator coils.
Depending on your exact model, the defrost drain might look like the one below instead. The aluminum piece you see circled is connected to the defrost heater and goes directly down into the drain.
The aluminium heats up and helps keep the defrost drain from completely freezing over. That’s the idea at least.
How to order Amana refrigerator replacement parts
Hopefully you were able to discover exactly what’s causing your Amana refrigerator to not cool properly.
If you found a bad or defective part, you’ll need to replace it.
Start by opening up your refrigerator door and looking on the side wall. You should see a sticker with all the details regarding your appliance.
You’ll want to take down the exact model number of your refrigerator.
Finally, type that model number into AmanaParts.com and locate the exact part you need.
Amana refrigerator user manual
Now that you have your Amana refrigerator model number, you can type it into the search bar of Amana.com and pull up the user manual from your fridge.
The user manual will likely have some additional, model specific troubleshooting steps you can try in addition to what I’ve described here.
If your Amana refrigerator is still not cooling, you’re likely looking at a bad control board, broken compressor, or a sensor that has failed somewhere in your appliance.
Unfortunately, these types of fixes typically require a trained professional. I’d start by contacting Amana support.
