Bosch Refrigerator Not Cooling after Power Outage – Quick Fix

If your Bosch refrigerator stops cooling after a power outage, check the compressor. Listen to the sound the unit makes when you turn it on. If you hear a clicking sound coming from where the compressor is, then you know the compressor is faulty.

You can also check the capacitor because it is the component that energizes and boosts the compressor. In fact, it is more likely to be a problem than the compressor. You know it is faulty when you hear a clicking noise from the compressor.

Call a qualified refrigerator repairer to take a look at it because replacing a compressor or a capacitor is not an easy task.

A cooling problem in your refrigerator arises after a power outage if the compressor is not getting an adequate supply of power. This makes it difficult for it to restart.

Bosch Refrigerator Not Cooling – Causes and Solutions

Here are some things to check if your Bosch refrigerator is not cooling and how to fix them:

1. Dirty Condenser Coils

The first thing to do if your Bosch refrigerator is not cooling is to check the condenser coils. You will find them at the back or bottom of the unit. If they are dirty, clean them thoroughly.

2. Faulty Condenser Fan

Be sure that the condenser fan is spinning well, without any hitch. If this is not the case, remove every obstacle in its way by cleaning it thoroughly.

3. Malfunctioning Compressor

Your refrigerator could be running, with the lights on but will not be cooling if the compressor is bad. However, a faulty compressor is very unlikely as compressors don’t fail easily.

To be sure, call a qualified repairer to take a look at it.

4. Defective Evaporator Fan

Check the evaporator fan behind the wall of your freezer. If it is faulty, then it cannot push cool air over the evaporator coil. This, in turn, will cause the freezer and fridge compartments not to get cool.

Replace the fan motor if the fan is bad. Remove the evaporator panel behind the unit and you will see the fan. Remove the clip used to mount it, the blades and the wire harness. Put the new fan motor into the harness and insert the motor into its housing. Put the blades back and remount the clip. Attach the evaporator panel back and the fan is good to go.

5. Stuck Air Damper

This is the component that controls the amount of cold air that travels between the fridge and freezer. It is found between the freezer and fresh food compartment. If you find that it cannot open or close, then cool air cannot flow into the fridge from the freezer.

But before you check all these complex stuff, check the easy ones first…

Bosch Refrigerator Not Cooling – Blocked Air Vents

Some food items or products could be blocking the air vents in the freezer or fridge. Cold air won’t be able to circulate properly if this is the case. Leave the vents free from any obstruction.

Bosch Refrigerator Not Cooling – Reduced Temperature

Check the thermostat to be sure you didn’t mistakenly increase the temperature. Depending on your model, the thermostat could be either under the fridge or in the back of your unit.

Bosch Refrigerator Not Cooling – Unplugged Refrigerator

As ridiculous as this may sound, many people unwittingly unplug their units and worry when their refrigerators stop cooling. So check to be sure it is well plugged in and that the circuit breaker is not shut off.

Bosch Refrigerator Not Cooling – Faulty Gaskets

If the gaskets of your refrigerator are bad, then warm air will continually seep into the unit and reduce its coolness. Change them if this is so. Additionally, ensure that the doors are always properly closed at all times.

Call the Bosch help center for repairs, especially if you still have an active warranty.

These repairs are applicable to all models of Bosch refrigerators.

Bosch Freezer Not Cold Enough – Solved

If your Bosch freezer is not cold enough, check the condenser coils, start relay, evaporator fan, or thermostat. The condenser coils should be clean to keep the system from overheating. They release the heat from the system to keep the compressor and coooling system working. Otherwise, the freezer will have difficulty cooling.

Ensure the start relay to se if it is working. You will find it attached to one side of the compressor. Pull it out and shake it for a rattle. Replace the relay if it rattles or run a continuity test between the run and start terminals using a multimeter. If the relay shows no continuity, replace it.

You may also want to check the evaporator coils and fan; the fan circulates the cold air from the evaporator coils. But if the coils have frost, the cold remains trapped and prevents air circulation. And if the fan stops working, the cold air does not circulate well, leaving warm and cold pockets in the freezer.

Thaw the coils if they are significantly frozen; leave the door open, or use a hair dryer to melt the ice quickly. Leave the door open until the ice melts. Then, you can test the fan motor using a multimeter. replace the evaporator fan if the motor shows no continuity or the blade is damaged.

You can test the thermostat by turning it from low to high and waiting for a click. If it clicks, the thermostat works well. But if it does not click, you may need to replace the part. Before that, check to see if it has continuity using a multimeter; replace the thermostat if there is no continuity.

There is also a chance that the main control board has malfunctioned. However, it is rare for control boards to fail, and you can easily misdiagnose them. So, ensure you check other parts before the board. Have an appliance technician correctly test it, so you do not throw out a good control board.

Bosch Refrigerator Not Cooling Properly – Quick Solution

Check the condenser coils for dust or dirt. If they are very dirty, then clean them thoroughly. Doing this will allow a good flow of cool air to pass through the unit.

The refrigerator will not cool properly if the coils are dirty. This is because the fan motor of the condenser pulls air through the coils over the compressor. And dirt or dust will reduce the efficacy of the condenser coils, causing the compressor to perform minimally. This will affect how well the refrigerator functions.
