10 Bosch Refrigerator Problems And Troubleshooting

If your Bosch refrigerator isn’t functioning correctly, does not cool water, or makes ice, and you fear that your food gets rotten, don’t worry; the 10 Bosch refrigerator problems below might be the real troublemakers, so let’s find the solution. 

Temperature Fluctuations

The refrigerators’ temperature often fluctuates for many reasons, and Bosch refrigerators users also often ask why. The main troublemakers are

Condenser Coils

If the condenser coils of your Bosch refrigerator gets dirty and clogged, it will cause fluctuation in the temperature. As these coils are an essential component, any problem in their functioning will cause the refrigerator to stop cooling properly. 

To save your fridge from this situation, use a coil cleaning brush of good quality or vacuum carefully to clean the debris from condenser coils.

Thermostat

The thermostat is another essential component; your refrigerator will encounter temperature fluctuations due to any fault. Though you can check your fridge’s thermostat by using a multimeter, the best way is to seek professional help. 

Fan Motor

If there is an issue with the fan motor, It will cause temperature fluctuations. Repair or replace it with the help of professionals. 

Door Not Closing Properly

If your Bosch refrigerator’s door isn’t closed correctly, It will not only affect its efficiency but also be a mere waste of electricity. You can solve this problem by 

• Worn-out or damaged door seals don’t allow the door to close properly and need immediate replacement. 
• Misalignment occurs due to the frequent use of door hinges. When your refrigerator door hinges wear out, replace it, and in case of misalignment, repair it.
• An unbalanced fridge also causes issues with the door closing. You can use a spirit level to check the level. If the refrigerator is unstable, immediately level it.
• Check the fridge properly; maybe any utensils cause hindrance in the door closing. Moreover, the door gasket gets dirty due to the accumulation of debris. Take warm water with any mild detergent to clean the door gasket because a dirty one doesn’t allow the door to close. 

Strange Noises

Instead of cooling or defrosting issues, sometimes we are annoyed only because of the whining or grinding sound. The reasons are many, but the most common are fridge fans; either their blades or motor may be the troublemakers. So, start with the fan blades.

Fan Blade:

Fans are constantly working, and sometimes rust or debris accumulates on the blades, which makes them produce a loud sound. The solution is easy: just remove the freezer compartment back panel. There, you see the fan; check its blades by hand; if they move freely, it’s okay. Otherwise, clean them. If you see large debris, blow it off, or you can use a hose to remove small debris particles. Follow these directions and you shouldn’t have any Bosch refrigerator problems.

Evaporator Fan Motor:

Another culprit may be your Bosch refrigerator’s evaporator fan motor. If it starts to wear down, you will hear a loud noise, especially when you open the fridge door. In that case, you have to replace the motor and fan immediately.

Condenser Fan Motor

Underneath your Bosch refrigerator, near its back, is the condenser fan motor. Mainly, the debris accumulation causes issues that you can easily solve by unplugging the fridge, removing the rear access panel, and removing the thing that causes obstruction. 

Fridge’s Compressor

Though the fridge compressors are reliable and durable enough to work for long years, you will hear louder noise when they start wearing out. Repair it from some professional. 

Loose Parts

If any screw or bolt of your Bosch refrigerator gets loose, it will also increase the sound. So for that, inspect yourself or seek a professional’s help. 

Balance the Fridge

If your fridge is not balanced or leveled, it creates noise. Remember that the fridge should be leveled; don’t miss this point. So, level it immediately. 

Water Inlet Valve

A water inlet valve may be an issue, which is solved only by replacing it with a new one. You can easily find it if you hear the noise while your fridge’s ice maker is filling.

Bad Smell

A bad smell from the fridge is something that is unbearable for everyone. It is actually one of the most common Bosch refrigerator problems. This unpleasant problem should be resolved, but you must find the reason for the smell before that. 

• Spoiled food or expired things cause the smell; if your refrigerator has such things, discard them immediately.
• The smell may be coming from the drain pan due to the drained water that comes from the freezer after the defrosting cycle. The reason may be clogged or debris, so you should clean the drain pan. Take a mild detergent and wash it with warm water. 
• The air inside the fridge contains different kinds of odors and impurities. In order to keep the air clean, refrigerators have air filters, which are sometimes dirty or clogged due to filtration. So replace the air filter immediately to solve the issue. 
• Moreover, if there is any smell in your fridge, just use mild detergent and warm water to clean its interior. Keep cleaning regularly until the smell goes away. 

Not Cooling Properly

The fridge’s main purpose is to cool things down; if the cooling system doesn’t work, how could you neglect this point? 

• You should check your Bosch refrigerator’s condenser coils. Dirt and debris accumulate in these coils and cause issues in dissipating heat from the coolant. You can find these coils in your refrigerator’s base or on its back; clean it with a stiff brush or an air compressor to remove the issue. 
• In case of a faulty compressor, either broken or malfunctioning, your fridge becomes unable to cool things. Replace your refrigerator’s compressor immediately.
• Broken condenser fan blades or motors are also another reason for this issue. You can solve it by replacing the damaged part.
• The evaporator fan moves air across the evaporator coils. If you find a fault in the fan or motor, you have to replace the defective piece.
• If the blade or motor of evaporator fan gets damaged, you have to replace the defective part. 
• Start relay makes your refrigerator work smoothly. Many people often called it start winding or compressor start switch. If any fault occurs to this component, the freezer and ice maker can’t work properly. Test its continuity and if you find any lack in it, it means the relay needs a replacement. The smell of burning wires indicates that there might be a short circuit. So you have to replace the relay to prevent further damage.
• Faulty temperature control thermostat creates issue. Number of other issues include start capacitor, Control board, main control board, or thermistor.

Frost Build-up & Not Defrosting

You have often seen frosting in your refrigerator. Defrosting is necessary because the frosting cause ice buildup, which is not good. Find out why your refrigerator has too much frost.

• If the damage occurs to the door seal and warm air enters into your refrigerator, it causes frosting. 
• If you see a clog in the defrost drain you can clean it to get back your efficient fridge. A pipe cleaner or turkey baster will help you to solve the problem. 
• Heater or thermostat may also cause issue, replace it in case of damage. 

Bosch refrigerator provides an easy solution like automatic defrosting system. Problems can occur to this automatic system also and make it stop working. Some problems are

• If your fridge’s defrost control board has a fault, it doesn’t allow ice or frost to melt down.
• Defrosting timer regulates the defrost cycle several times in a day. When there is an issue in it, it doesn’t give power to defrost heater and demands replacement. 
• The function of defrost heater assembly is to melt down the frost accumulated on the evaporator coils. Unplug your fridge and open the upper freezer corner. Then unscrew the five screws of heater and test continuity with a multimeter. You have to replace the heater in case of no continuity. 

Water Leakage

Many people complain that they find water beneath the refrigerator. Several things can cause this water leakage like

If your fridge’s defrost drain or ice maker’s water supply line has freezed up, the water may leaks. Clogging in them also cause issue and you can use pipe cleaner or a turkey baster for cleaning. 

If there is any damage or clog in the water inlet valve and water filter, the water may leak. So, replace any damaged part to resolve issue. 

Ice Maker Problems

Ice makers in Bosch refrigerators are great and efficient in work. As faults may occur at any time, ice maker will stop working. If there is change in the freezer temperature settings like above or below 0 to 5 degrees Fahrenheit, ice maker will not make ice. Some other trouble-making components are. 

• Water Inlet Valve: Insufficient water pressure (below 20 psi) can hinder ice production. Confirm proper water pressure.
• Power to Valve: Test water inlet valve power with a multimeter. If you find an issue, replace the water inlet valve.
• Ice Maker Assembly: If some components are damaged that are replaceable, replace them. Otherwise, there is a need to replace the whole assembly. 
• Faulty Door Switch: The door switch is an essential component; test door switch continuity; replace if it lacks continuity.
• Ice Level Control Board: With the help of sensors, they allow water to enter the system when the ice isn’t in the bin. In case of a fault in it, either too much ice or no ice production. Thus, you have to replace the board. 

Water Dispenser Is Not Working 

Water dispenser malfunctioning is common among those Bosch refrigerators which contain this feature. Let’s find out what causes your refrigerator’s water dispenser to be in trouble. 

• Low temperature causes ice-making in the water supply tube. So, disconnect the supply line and blow air into the tube; if the air doesn’t pass, let the ice melt. Also, raise the temperature to prevent the supply tube from getting frozen. 
• Keep the water pressure around 20 psi; below one may stop the function. The optimum pressure is needed to open the cold water valve, which provides water to the dispenser. Defective water supply lines also cause hindrances.
• The circuit board is responsible for the proper functioning of the dispenser system. Any disturbance in the circuit board will cause the water dispenser to stop working. You have to replace the defective piece and for that ask any professional.
• The dispenser system also has a few switches that send voltage to a mechanical component. In case of an issue, the Bosch refrigerator refuses to dispense water or ice properly. You can use a multimeter form to diagnose the defective piece for replacement.
• If your fridge door isn’t closed properly, the water dispenser system will not start working. Thus, first, repair the fridge door. Moreover, water filters also cause this issue due to clogging, so keep the filters changing after 6 months for proper functioning. 

Ice Dispenser Issues 

Ice dispenser is different from ice makers as their work is to dispense the ice when you need it for convenience. Not all Bosch refrigerators have ice dispensers, but a few designs do. So, maybe you encounter a situation where your fridge can make ice but cannot deliver it to you due to any fault in the ice dispenser. 

There are rare chances that the dispenser stops working, but for some reasons, it might happen, such as damage or fault in the dispenser’s switch or control board. It might involve a dispenser motor, ice-pushing auger, or ice-crushing blade. In all such scenarios, you have to replace the faulty system.
