Why is Your Hisense Refrigerator Not Cooling?

A not-so-chilly Hisense refrigerator is a common problem among various homeowners. So, your mischievous fridge is not an exception. The problem lies in identifying the bad parts contributing to this issue and finding the correct remedy. But you might get puzzled, as you try to determine the real culprits.

Whether a blocked vent, an overworked compressor, or a refrigerant leak, understanding the cause empowers you to diagnose and potentially fix the issue. Doing so will save you from food spoilage and service call stress.

Now, without further ado, let’s meet the failed parts responsible for this cooling conundrum.

1a- Faulty Evaporator coils

Sometimes, you may confuse evaporator coils with condenser coils. However, these coils differ in their locations, appearances, and functions. The former absorbs heat from the inside of the refrigerator. This causes the refrigerant to evaporate and turn into a gas.

While located outside the fridge. The condenser coils Release the heat absorbed by the refrigerant in the evaporator coils. This makes the refrigerant condense back into a liquid state.

Now that we have cleared this common confusion, it’s time to understand why the evaporator coils may malfunction. You can blame either wear and tear or frost buildup.

Eventually, these coils will make your Hisense fridge struggle with temperature regulation.

1b- How To Fix Faulty Evaporator Coils

Fixing failed evaporator coils isn’t a problem for an experienced DIY expert with an in-depth understanding of the latest repair technologies. Follow these steps and get these coils back on track.

  1. Unplug the appliance: Remember, removing the fridge’s plug  power cord) from its power outlet is essential with every Hisense refrigerator troubleshooting procedure.
  2. Locate the coils: Find these coils behind the back panel in the freezer or refrigerator compartment.
  3. Remove the back panel: Use your Phillips screwdriver to detach the rear panel.
  4. Get rid of frost buildup: To remove frost buildup choking these coils, you can use a brush or a vacuum cleaner with a nozzle attachment. Also, you can use some warm water to speed up the deforestation process. Running a defrost cycle can easily resolve this cooling issue in many Hisense models.
  5. Check for damage: If the problem is physical damage to the fins, you should replace the punctured coils. Refer to the manual or call in a pro technician.

2a. Faulty Thermostat

The thermostat of your Hisense refrigerator is the mastermind behind regulating the machine’s temperature. This component orchestrates the cooling cycle and monitors the interior temperature. Then, it signals the compressor to step in when warmth emerges.

Your fridge thermostat can malfunction in two different ways:

  • Misreading cooling signals: A malfunctioning thermostat may misread the temperature as too warm. This forces the compressor to work round the clock, even when the fridge is already cool.
  • Failure to catch rising temperatures: In this case, the fridge will keep warming up beyond safe levels, leading to spoiled groceries and potential health concerns.

2b. How To Fix Faulty Thermostat

In most cases, a defective thermostat needs a replacement. To replace this component successfully, you should do the following:

  1. Locate the thermostat: It is hidden behind a panel at the back of the fridge’s interior. you’ll easily find them near the evaporator coils.
  2. Loosen the screws: Use a flathead screwdriver to remove the panel’s screws. Then, use a wrench or pliers to detach the thermostat and disconnect its wires.
  3. Attach the new thermostat: Install the new thermostat and fit it exactly where the old one was.

Before jumping to the replacement step, you may want to check the settings of the thermostat. Ensuring that it is set to the correct (cool/heat) mode may resolve this problem.

Also, try to remove dust and debris on the thermostat and test it using a multimeter for resistance. If none of these steps saves the day, skip to the replacement part.

3a- Evaporator Fan Issues

While playing a pivotal role in the cold air circulation within your Hisense fridge’s shelves and drawers, it may occasionally falter. Without proper circulation, cold air gets trapped in pockets, leaving other areas stagnant and warm. Typically, this leads to the spoilage of much food and other groceries.

3b- How To Fix Evaporator Fan Issues

Safety always comes first. So, don’t make any repairs unless you disconnect power from your Hisense Refrigerator that is not cooling.

  1. Track the fan’s location: Your evaporator fan lurks behind the freezer’s back panel. By default, it resides near the evaporator coils.
  2. Access the fan: Grab a suitable screwdriver. If confused, consult your manual for the specific type. But usually, a standard flathead screwdriver comes in handy.

Remove the delicate screws securing the access panel. Handle these screws with care.

  1. Scour for wear and tear: Thoroughly check the fan assembly for visible cracks or wear signs. If found, it indicates a need for replacement. Employ a wrench or screwdriver to dismantle worn components. This facilitates the seamless installation of their fresh counterparts.

This easy appliance repair doesn’t need a qualified technician. However, you need to employ your proven DIY repair skills. Still, if at any point, you feel stuck, don’t delay that call any longer.

4a- Defective Temperature Control Board

While some users confuse this board with the thermostat, both function differently. The temperature control board relies on the thermostat that senses the actual temperature of your Hisense refrigerator. Then the thermostat signals the board about the temperature situation. depending on this signal, the board determines how to adjust the cooling system.

A defective board usually misreads the temperature signal. This makes the board urge the compressor to work overtime even when the fridge is already chilly.

On the contrary, a malfunctioning temperature board may fail to notice the rising temperature of your Hisense refrigerator. This ends up with a continuous temperature rise in your fridge that goes unnoticed.

The good news is that you can rely on the board’s display panel to identify any troubles in this component. While most Hisense refrigerator models come with this panel, others have physical buttons to adjust the temperature. Either way, you can find an easy solution for this frustrating appliance issue.

 4b- How To Fix Defective Temperature Control Board

Have you tried troubleshooting other components and the lukewarm frustration persists? Well, it’s time to blame the main control board for the appliance’s temperature. While replacing it might seem like a major fault, fear not! With a keen eye for detail and the right tools, you can diagnose and potentially fix this issue yourself. Here’s how:

  1. Use the demo mode: This is an optional step but is indicative. this mode bypasses the temperature control board. Consult your manual for activation instructions ( it usually takes a bush of a button). If the fridge cools in demo mode, the board is likely faulty.
  2. Look behind the control panel: This board is situated right behind the control panel in the fridge compartment.
  3. Access the panel: The panel of your Hisense fridge is secured with either screws or plastic tabs. So, remove them with a screwdriver or simply pry the tabs open.
  4. Perform visual inspection: Search for burn marks and loose connections. When found, replacement is mandatory. If you are not familiar with manipulating electrical components, it’s better to seek professional help.

5a. Defective Door Switch

This tiny exterior component is where the cooling magic begins. Once the fridge’s door shuts correctly, it signals the control board to initiate the cooling system. So if something goes wrong with this switch, there won’t be any type of cooling. The fridge won’t be able to identify a closed door and subsequently, the cold air will escape the appliance.

5b- How To Fix Defective Door Switch

While troubleshooting the door switch, it is worth taking a look at the seal. A worn-out door seal may be another sneaky culprit behind this cooling disappointment.

Here’s what to do to troubleshoot a bad door switch:

  1. Find the switch: Search for the door switch near the door hinge. It’s located on the door or its frame depending on the Hisense fridge you have.
  2. Remove the covering: The switch is guarded by a covering. So, use your screwdriver to detach it.
  3. Look for physical wear: As with any damaged component, replacement is advisable in the event of apparent damage. Use a multimeter to be 100% certain of its malfunction.
  4. Do some cleaning: If the switch passes the test, it just might be blocked by dust. You can use a vacuum cleaner or an air duster to restore its cleanliness and functionality.


Now that we’ve discussed the easier ways of troubleshooting a Hisense refrigerator not cooling, you can revive its cooling efficiency and restore the optimal airflow. Remember, safety first and you can ensure it by disconnecting the fridge from the power source.

Then, you can rely on your DIY skills, trusty tools, and our detailed guide for handling the frustration of a lukewarm Hisense refrigerator.
