Common refrigerator problems and how to fix them
04.06.2022 | GlacialPure | GlacialPure Blog

Now everyone has an electrical appliance in their home—refrigerators. Refrigerators make our lives more convenient, and refrigerators have more and more functions. In the process of using refrigerators, we will inevitably encounter some problems. This article will list them.  Help you solve it.


1. The floor under the refrigerator is leaking

If your refrigerator is leaking, it can be dangerous for anyone who is in the kitchen a lot. Refrigerator leaks due to clogged defrost drain. The defrost drain is usually located on the back wall of the refrigerator, just above the slope from the floor to the back. A buildup of food particles or debris can clog the drain hose, causing ice to build up and water to leak out of the refrigerator and freezer. To fix this, try using warm water to drain the hole from the inside. Use a slender tool, such as a pipe cleaner or turkey masher, to remove the blockage. If that doesn't get the job done, you may have to manually remove any buildup clogging the valve at the end of the drain hose. Pull the refrigerator away from the wall to find the defrost drain hose on the back of the service panel. The hose should have a rubber valve to help trap debris and prevent clogging. Clean the valve with hot water and soap, then reinstall.

A clogged or frozen water supply can also cause water to leak on the floor and create puddles under the refrigerator - which can also prevent the ice maker and water dispenser from working properly. To fix this, unplug the refrigerator and find the shut-off valve. The valve might be under the sink, behind the refrigerator, or under the refrigerator in the basement or crawl space. Once you find it, make sure to close the shutoff valve and check for any problems in the plastic supply line. If damaged or torn, the water supply line will need to be replaced.

If your water pipes are damaged, you can still use the refrigerator to chill food. You will not be able to use the ice maker or water dispenser.


2. The temperature of the refrigerator is not low enough

This is a common problem that is usually easy to fix. If you notice this problem in your freezer, check to see if the back wall of the freezer is cold.

If it's cold, check to see if you can hear the evaporator fan running or if you can feel air coming out of the freezer vent. If it can't, then it's most likely a problem with the refrigerator's evaporator fan. If you can feel the air moving and hear the fan running, you should check your refrigerator's compressor. These are condenser coils that release the heat from the inside of the refrigerator into the room. Clean any dust that might be preventing air from passing through the coil. If your condenser coils are clean, it might be time to invest in that nice French door refrigerator you've got your eyes on.


3. The temperature in the fresh area is too high

The cold air produced by the refrigerator comes from the freezer unit and then flows into the fresh food section of the refrigerator. So if your fresh food compartment is heating up, it's likely because you have airflow issues.

Your refrigerator contains an evaporator fan, which is responsible for moving cold air from the refrigerator to the fresh-food compartment of the refrigerator. This air moves through a diffuser located behind the fresh food section of the refrigerator. If you can hear the evaporator fan running or feel the air blowing from the freezer vent and are still facing the problem, your diffuser ducts may be clogged with ice. This blockage prevents air from passing through the system and is usually caused by the door being left open for long periods of time.

If you can't hear the evaporator fan running or hear an unusual humming noise, you most likely need to buy a new motor for the evaporator fan.


4. The refrigerator temperature is too low

A refrigerator that is too cold can cause food to freeze or spoil. Most of the time it is the result of a malfunctioning temperature control thermostat. This thermostat is responsible for regulating the power flowing to the compressor, evaporator and condenser fans. Turn the temperature control thermostat all the way. You should be able to hear a click when you reach the end. If there is no sound, the thermostat should be removed and tested with a continuity checker.

Defective thermistors can also cause excessive freezing. This device is mainly responsible for monitoring the air temperature in the refrigerator, and is

Usually attached to the PCB. Any type of problem with the thermistor can cause the refrigerator to fail to stop its cooling cycle.

This type of problem can also indicate a defect in the temperature control board, which controls the voltage supplied to the compressor and fan motors. This type of refrigerator failure can be difficult to diagnose.

In rare cases, this may indicate a problem with the refrigerator's main PCB.


5. Refrigerator ice maker not working

The ice maker must operate optimally when the temperature is set between 0 and 5 degrees Fahrenheit (-18 and -15 degrees Celsius). If the freezer temperature exceeds 10 degrees Fahrenheit (or -12 degrees Celsius), the ice maker will not function properly.

You can use an ohmmeter to check the ice maker switch continuity. In case of failure, the switch can be replaced.

Most refrigerators use infrared sensors to track ice formation inside the ice bucket. When ice begins to fill the bucket, the infrared beam is blocked, automatically shutting down the ice maker. If this ice level control board fails and the sensor does not work properly, the ice maker will stop making ice.

The ice maker's control unit includes a thermostat called the ice maker mold thermostat that tracks the temperature of the ice maker/tray. When the mold reaches a certain temperature, the ice cubes are ejected from the tray and filled with water. A non-functioning thermostat will keep the ice maker in its current mode and no more ice will be produced. In this case, this thermostat should be replaced.

Failure of any of the components that make up the ice maker assembly, especially the control circuitry, can cause such problems. Most of these components cannot be secured, and the entire assembly may have to be replaced.



6. Water dispenser not working

There are several possible sources that may be preventing your water dispenser from working.

The first and most common cause is a frozen water pipe on your door. To determine if this is the source of the problem, disconnect the tube at the bottom of the door and blow air through it. If air doesn't get through, your water line is frozen. To fix this, unfreeze it. To prevent this from happening again, be sure to regularly check that your refrigerator is set to the proper temperature. You should set it between 0 and 10 degrees Fahrenheit. Below this value, the waterline may freeze.

Another possible cause of this problem is a faulty inlet valve. This valve opens the water supply to the dispenser; therefore, if the valve is defective or the water pressure is too low, the water valve will not open. Before jumping to conclusions and purchasing replacement parts, check that the water pressure on the valve is at least 20 psi.

Insufficient water pressure may prevent your water dispenser from working. Because the water inlet valve needs at least 20 psi to function properly, this may be the cause of your problem. Check the flow of the house's water supply to see if the water pressure is at least 20 psi.

A problem with the refrigerator water filter prevents the water dispenser from working. The water filter is an important part of the water dispenser and is usually replaced after 3-6 months or 300 gallons of water. Expired water filters can cause some problems, the water you drink contains harmful substances, the water tastes weird, the smell is bad and a series of problems, which can cause harm to your body and your family.


7. The refrigerator makes abnormal noises

If you're dealing with a noticeable noise when the freezer door opens, this could indicate a problem with the fan blades. The fan blades located in the back panel of the freezer make a noise when they encounter any obstructions. You can also check the blades of the condenser fan located under the refrigerator towards its rear end. It could also indicate a faulty condenser fan motor or its bearings.

Refrigerator noise can also be the result of wear on the evaporator fan motor. This type of noise is also more noticeable when the freezer door is open.

While compressor noise is common, an unusually loud compressor can indicate worn components and near failure.

Your refrigerator is one of the most important appliances in your home. Knowing which symptoms to look out for and knowing how to address them can save you a lot of time and money.
