Blomberg freezer and refrigerator problems can create major problems and may even lead to food spoilage. If you notice that your Blomberg freezer and refrigerator are not maintaining food at the proper temperature, you must solve the issue as soon as possible. The good news is that many of the issues that cause freezers and refrigerators to become too hot can be fixed through a couple of easy steps. In this post, we’ll examine the most commonly-cited reasons for warm refrigerators and freezers from Blomberg and offer step-by-step directions for fixing them. It doesn’t matter if you’re a seasoned DIYer or just starting out, we’ll give you the knowledge you need to get your fridge and freezer back to their proper temperature.
Control of the thermostat or Cold Control
The cold control is a temperature-controlled switch that supplies power to the compressor and fan circuits in the refrigerator. If the compressor or fans are functioning normally, but not running frequently enough or sufficient to maintain proper temperatures in the freezer and fresh food sections The cold control could be malfunctioning or not in calibration. Normal temperatures for fresh food are in the 38 degree Fahrenheit range with the control set to mid-point. Check to ensure that the capillary tubes or sensing bulb isn’t damaged or out of position and that the wire terminals aren’t loose or corroded.
Unplug the Blomberg refrigerator before beginning and then open the Blomberg refrigerator’s doors and locate the control. It is usually found just behind the temperature control knob and is typically located in the fresh food section of the control panel.
Take the control off the appliance and turn it on to the warmest setting. After that, set your multimeter until RX1 is set to connect to the terminals.
You’re testing for continuity and you should see a reading that reads infinity. While the probes are still on to the terminals adjust the controls to higher (colder) and higher settings. The reading should be changed to zero, indicating that there is continuity.
If your control fails one of the tests above, you will need a replacement Blomberg cold and temperature control.
Evaporator Fan Motor
When the compressor is on, it is the Blomberg fan motor circulates cool air throughout the refrigerator. The fan could fail, and temperatures in both the freezer and fresh food sections will slowly rise. In the event of this then the compressor will be more frequent and take longer than normal. The compressor should be running whenever you hear the fan in the condenser and evaporator fans.
How to check the Blomberg refrigerator fan motor:
Connect the Blomberg refrigerator’s power source. Also, take the evaporator fan covers from the freezer compartment.
The motor shaft should spin at a brisk pace, with no resistance. try turning the shaft manually to check for resistance.
If you notice a large amount of ice covering the motor, defrost your freezer and see if that resolves the issue. You should also inspect the motor for any signs of wear or damage.
It is necessary to purchase an replacement motor for your Blomberg If you’re not able to turn it on or see any wears on it.
Electronic Control Board
Some newer models of Blomberg refrigerators might have an electronic control board. The control board is linked to thermometers or temperature sensors. These are used to check the temperature in fresh food and freezer compartments. The control board makes use of this information to control the operation of the compressor, fan motors, and the defrost system. The electronic control can be the cause in the event that the temperature gets too high. Blomberg’s electronic controls can be complex and expensive and usually reliable. Therefore, you must first confirm that all the other components , including the compressor, fans and sensors are in good working order prior to condemning the control. Some manufacturers may provide specific information that will aid in diagnosing a malfunctioning control.
How do you check your Blomberg refrigerator’s control board
Before you begin, unplug your fridge before starting. Then, you will work with electrical components.
Locate and take out the control board’s electronic circuit from the appliance. It’s in the Blomberg refrigerator, inside of the control box, which is usually attached to the side or top of the fridge.
Be sure to check your control panel for any signs of worn foil, damaged or damaged, burnt connections and arcing or other signs of damage.
If you find one of these you’ll need a replacement electronic control board for Blomberg.
Temperature Sensors or Thermistors
In models that use an Electronic Control, a thermistor or temperature sensor might be used to monitor fresh food and freezer temperatures. The sensor is a small capsule that is covered by a plastic shield and will vary in resistance according to the temperature. The control board uses this information to switch on the fan and compressor circuits, as well as manage the damper control on certain models. If a sensor is damaged or defective , it could in error signal the controller to shut off the compressor and fans and lead to warmer than the normal fresh food or freezer temperatures. The individual manufacturers might have specific information to check these sensors according to the model in question and could also include an error code to the control board’s electronic component on certain models.
How to test the temperature sensor of an appliance using a multimeter
Begin by disconnecting your Blomberg refrigerator. Then, remove the front panel of your refrigerator to reveal the control board that is in the middle.
The thermistor(s) will be connected to the main control board. Then, remove the thermistor(s) from the appliance in order to check them.
You’ll need to test them by placing the thermometer(s), in the ice bath for 5 minutes in order to raise the temperature to 32°F.
If you connect the probes to the terminals and your multi-meter set to Rx1 You should get the reading of 16,600 ohms (+/- 5 percent).
If you get a reading that is not within this range, you’ll require an replacement temperature sensor from Blomberg or the thermistor.
The defrost-timer is an electronic timer. It is controlled by a set of contacts that control both heater and compressor circuits. The timer triggers a defrost sequence every 8-10 hours. It happens approximately once per daily. The defrost timer is typically set to terminate the defrost cycle after 20 to 30 minutes . Then the compressor and fans will then begin.
How do you test the refrigerator defrost timer with a multimeter
Find the timer for defrost by disconnecting the appliance from its source of power. It’s located in the lower part of the refrigerator’s kickplate or on the control panel of the Blomberg refrigerator. It could be located behind the refrigerator’s back wall.
After locating it, remove the defrost timer of the appliance in order to check it.
Utilizing a multi-meter with the Rx1 setting using one probe that is touching the terminal that is common to all (it must be labeled “3” or “C”) Then, you can connect the other lead to the other three terminals remaining, one at a time. Examining the first pair should result in a reading of or near zero denoting continuity. The second pair might also produce readings of zero or near zero. The third pair should also be examined and the reading must read infinity.
The readings could not be taken into account by you. You will need an replacement timer for Blomberg.
The Blomberg safety thermostat, that is linked to the heater for defrost, can be utilized to stop the defrost process at a certain temperature. It is usually rated at between 38 and 47 degrees Fahrenheit. If the thermostat is inoperable and remains in open circuit the heater for the defrost will not be powered up and defrosting won’t occur.
How do you test the thermostat of a refrigerator’s defrost using a multi-meter
Unplug the Blomberg refrigerator, and then locate your refrigerator’s thermostat for defrost. It may be under the floor or in the back of freezers with tops. The thermostat that controls defrost can be found on the side of a side-by side refrigerator.
Once you’ve found it, take off the thermostat to allow you to test it. It is necessary to take out all objects blocking your path, such as the contents of the freezer, shelves for freezers as well as icemaker components, and the back, rear, or bottom panel.
Set your multimeter to the Rx1 setting. Each probe should be placed on an electrical wire for your thermostat. If your thermostat is not cold, it should show an 0 on the multi-meter. If your temperature is between 40 and 90 degrees Fahrenheit then it should read infinity.
If the results from your test are different from the ones listed here Then you’ll require a replacement Blomberg defrost thermostat.
The defrost heater is the appliance that melts the ice and frost from the evaporator coils. It’s usually a metal wire filament that is enclosed in an aluminum or glass tube. There might be more that one heater depending on the shape of the evaporator.
How do I test the temperature of a refrigerator’s defrost with a multi-meter:
Before starting, be sure your appliance is disconnected from the source of power.
Locate your defrost heater. You will find it behind the freezer compartment of your Blomberg refrigerator, or beneath the floor. Defrost heaters are commonly located beneath a refrigerator’s evaporator coils. You’ll have to rid the area of obstructions like the refrigerator’s contents, freezer shelves, icemaker pieces, and the bottom, rear, or bottom panels.
Before you are able to test your heater’s defrostfunction, you need to take it out of your refrigerator. Two wires connect the defrost heating unit. They are connected using connectors that slip-on. Securely grip these connectors and pull them off the terminals. To aid you get them off, employ a pair or needle-nosed scissors. Do not pull at the wires.
Test your multimeter the heater for continuity. Set your multimeter to the Rx1 scale and put the tester’s leads on one terminal each. The result should be anywhere in between zero to infinity.
You’ll require a replacement Blomberg heater if you get a reading below zero.
Condenser Fan Motor
Modern frost-free Blomberg refrigerators have condenser coils with fan cooling. It’s usually on the bottom of the refrigerator next to the compressor. In order to remove heat, the condenser fans circulates air around the coil. If the Blomberg refrigerator is more warm than usual and the compressor is running at a rapid pace, you might have an issue with the motor of the condenser. The condenser fan motor runs at the same time as the evaporator motor as well as the compressor. If the fan motor is not turning at all the condenser won’t be able to eliminate the excess heat and the compressor will run almost continuously
How to check the motor in a refrigerator condenser fan:
Begin by disconnection of the power source of the Blomberg refrigerator. Then, take off the access panel at the rear and locate the condenser fanmotor. It is usually located in the lower part of the appliance.
Once you have located it, Look for any debris or obstructions that could cause the fan to stop free movement. Also, look over the motor to see whether it shows any signs of wear.
You’ll require the replacement Blomberg condenser fanmotor when the motor has become seized or worn.
In conclusion it is clear that a Blomberg refrigerator or freezer that are overly warm could be a frustrating and costly issue. You can fix the majority of the issues with warm freezers and refrigerators by acquiring basic repair skills and some troubleshooting. From reviewing the temperature settings and cleaning the coils there are numerous actions you can take to restore the proper cooling function for your appliance.
