For further detailed troubleshooting to get your Haier mini fridge back cooling below

Ready, let’s jump in!

1. Check Haier Fridge is Plugged In

Although it may appear obvious, the first step is to ensure that your Haier mini refrigerator is properly plugged in.

If the appliance is not properly plugged in, remove the plug from the socket and re-insert it.

Remove the plug and try plugging another item into the same socket if it is properly inserted.

If the newly plugged-in item fails to function, try resetting the circuit breaker for that outlet.

If the outlet is still not working, call an electrician.

At the very least, you have a refrigerator that is cooling.

If the outlet is not the problem, move to the next step below

2. Check the Haier Fridge Door Shuts Properly

Fridge doors that do not close properly and damaged or worn-out seals are common causes of refrigerators not cooling.

Check to ensure that the door is properly closed. Failure to do so will result in cold air leaking out.

Check the door seals to ensure they are not torn, weathered, or dirty.

Dirty seals can cause gaps large enough to allow warm air to enter, affecting cooling.

If you notice dirty seals or frost build-up around the gasket, clean them right away and give your refrigerator up to 24 hours to return to normal temperature.

It is best to call a technician if the seals need to be replaced or the door is faulty.

3. Reduce Haier Fridge Temperature

The fridge’s temperature may need to be reduced, especially during warmer months or if the fridge is packed with food and drinks

Reduce the temperature of your Haier mini refrigerator.

The ideal refrigerator temperature is 3°C (37°F) and the freezer temperature is -18°C (0°F).

If your refrigerator is in direct sunlight or close to a heat source, consider relocating it if possible.

While we’re on the subject of fridge location, make sure there’s an inch of clearance between the fridge and the back of the wall for proper operation.

4. Check Condenser Coils

Fortunately, inspecting and, if necessary, cleaning the condenser coils is simple.

Here’s what you should do:

At the back of your Haier mini-fridge, there are a set of condenser coils that help keep your mini-fridge cool.

When they become covered in dust or frost, they can struggle to cool your fridge at the desired temperature.

Where is it? that Condenser coils are located at the bottom or on the back of the refrigerator

Inspecting the condenser coils is easy, just follow the steps below

Possible Solution

  1. Turn off the power to your mini fridge.
  2. Pull it away from the wall to gain access to the back.
  3. Locate the condenser coils and inspect them for frost or dirt.
  4. If the coils are covered in frost, turn off your mini-fridge and let them defrost before cleaning them. If they are dusty, wipe them down with a damp cloth.
  5. Restart your Haier mini fridge once it is clean.

Check to see if the fridge is cooling properly after a few hours.

If not cooling move to the next reason

5.  Faulty Condenser Fan

If cleaning the coils did not restore cooling to your Haier mini fridge, the next component to inspect is the condenser fan, which can occasionally stop working properly if it becomes broken or covered in ice.

The primary function of this fan is to keep the condenser coils cool, so if it fails, your coils will become too hot, and your Haier mini fridge will not be able to cool down.

Where is it? The condenser fan is located in the bottom cabinet by the compressor and the condenser coils. It is important to note that refrigerators with condenser coils on the back will not have a fan (check your user manual).

Possible Solution

  1. Turn off the power to your mini fridge.
  2. In your mini fridge, look for the condenser fan.
  3. Remove any coverings that are on it.
  4. Next, try manually turning the fan around.
  5. If the fan cannot move without being obstructed, try to remove the object obstructing it first, and if that fails, the fan may need to be replaced.
  6. If the fan is not obstructed, you must test the fan motor with a multimeter to ensure continuity.
  7. Replace the fan if it is broken. Reattach the fan cover and move on to the next reason if everything is working properly.
  8. Check to see if your Haier mini fridge can now properly cool down after installing a new fan. If not, continue to

6. Evaporator Fan

If your Haier mini fridge has an evaporator fan (check your user manual), it could be broken and causing your mini fridge to overheat.

This fan circulates air from the small freezer compartment (depending on if your model has a freezer) into the main body of the mini refrigerator to keep it cool. If it fails, your mini refrigerator will stop working.

Where is it? Behind the freezer wall is the evaporator fan. Before you can access your freezer, you must empty it of its contents and shelving. 

Possible Solution

If the fan does not appear to be working, the fan motor may need to be replaced.

Locate the fan and remove the mounting clip, fan blade, and wire harness after removing the evaporator panel in the freezer’s back.

Install the new motor into the housing and connect it to the wire harness.

Replace the mounting clip after completely inserting the fan blades. Replace the evaporator panel and the shelving.

7. Start Relay

The start relay is a critical component in your Haier mini fridge that allows the compressor to function.

If it fails, your Haier mini fridge will be unable to cool to the proper temperature.

Where is it? Remove the lower back panel from your fridge to access the relay

Possible Solution

  • Check that your mini-power fridge’s is still turned off.
  • Next Find the start relay (check your user manual if required).
  • Noting, the start relay is housed in the same compartment as the compressor and is connected to the main device at the back.
  • Carefully disconnect the wires from the relay.

The simplest and most effective way to determine whether or not the Start Relay is functioning properly is to perform a physical test by shaking it.

If you hear rattling on the inside of the start relay, the part is defective and must be replaced.

If it isn’t rattling and appears to be in good working order, you may have a problem with the compressor itself.

Repairing a compressor is far more serious and costly.

Life Expectancy of an Haier Mini Fridge

The life expectancy of an Haier mini fridge is somewhere between 6-13 years

The general rule of thumb is a budget refrigerator should last about six years.

A mid-range refrigerator should last about nine years, while a high-end refrigerator can last up to 13 years.

Faulty thermostats and damaged door seals are repairable and worn seals can help restore the cooling performance of an older refrigerator.

If your refrigerator is more than six years old and has a major fault (such as compressor failure), consider replacing it because a new one will be more efficient and have lower operating costs.

What the Reviews are Saying

Here are some comments made about the Haier fridge on various websites.


This is a great unit for a small man cave or dorm room.

It holds more than a 12 pack of your 12oz drink of choice with room for other small items. .

The freezer area is small but would do the trick for a small ice tray or maybe some frozen meals.

The only issue I have it the volume level of the compressor.

It’s a small fridge, so there’s not a lot of shielding around it to compensate for the noise.

It’s easy to get over but does get annoying while watching a movie.

Freezer compartment perfect for holding cold pack to apply to injury. Keep it under my desk.

Doesn’t hold much, but don’t need it to.

I bought this little fridge to keep some extra cool drinks, apples, and snacks in my classroom for myself and students who may not have a lunch for a day.

It does a great job keeping things cool and fresh. .

It took a bit an experimentation to find the right temperature adjustment because it cools so well but all was good after a few days.
