Cold Control Or Temperature Control
The cold control is a temperature-controlled switch that supplies power to the compressor and fan circuits in the refrigerator. The cold control may be out of calibration or malfunctioning if the fan and compressor are not operating correctly. The typical fresh food temperature is in the 38deg Fahrenheit range with the control set to the mid-point. Make sure that the sensing bulb or capillary tube is in good working order and the wire’s terminals aren’t become loose or corroded.
Before beginning, unplug your Samsung refrigerator before you begin. After that, you should open the Samsung refrigerator’s doors and locate the control. It’s located inside the control section for fresh foods on the panel, typically behind the temperature adjustment knob.
After taking the control out of the appliance, switch the knob to the warmest setting, adjust your multi-meter to the Rx1 setting . touch the probes to the terminals
The test is for continuity and you should be able to read infinity. Set the controls to higher (colder), and higher settings while the probes are still touching the terminals. If your reading shifts to zero, that means that you have continuity.
If your control fails one of the above tests the control will need to be replaced. replacement Samsung cold control & temperature control.
Motor for Evaporator Fan
The Samsung evaporator fan motor is used to circulate the cold air throughout the Samsung refrigerator while the compressor is in operation. If the fan is defective, then temperatures within the freezer area will rise slow, while temperatures in fresh food section will increase more quickly and the compressor will run longer and more frequently than normal. While the compressor is operating, you should also detect the evaporator fan operating simultaneously, as well as the condenser, which is close to the compressor.
How do you inspect a Samsung refrigerator evaporator fan motor:
Connect the Samsung refrigerator’s power source. Also, take off the covers for the evaporator fan from the freezer compartment.
The motor shaft should be able to flow freely and without resistance. To check for resistance, turn the shaft manually.
If you see a lot of ice on your motor It is recommended to open the freezer and defrost it and see if this solves the problem. Also, look over the motor for signs of wear and damage.
You will need an replacement Samsung fan motor If you’re not able to turn it on or see any wears on it.
Electronic Control Board
An electronic control panel could be found on certain Samsung refrigerators. Thermistors , also known as temperature sensors, are connected to the control board and used to check temperatures in freezer and fresh food compartments. This information is used by the control board for controlling fans, compressors, as well as the defrost process. The electronic control could be the cause for the problem if the temperature is too high. The Samsung electronic controls are costly, complicated and, in most cases, trustworthy. Before you dismiss the control, ensure that the compressors, fans and sensors function in a proper manner. Manufacturers may have specific information that will help you determine the cause of a malfunctioning control.
How to check the electronic control board on the Samsung refrigerator
Unplug the fridge prior to beginning since you’ll be working with electrical components.
Locate the electronic control panel and remove it from the appliance. It’s located inside of the Samsung refrigerator. The control box is located on the top of the refrigerator.
Check your control board for signs of damage, such as wear, burnt connections, or arounging.
It is necessary to replace the Samsung electronic control boards if you notice any of these signs.
Temperature Sensors or Thermistors
A thermistor, also known as a temperature sensor, can be utilized in models that feature an Electronic Control to monitor the temperatures of fresh foods and frozen food. The sensor is a tiny capsule-like device that is protected by a shield of plastic and is able to vary its resistance according to the temperature. The control board utilizes this information to switch on the compressor and fan circuits and also to control the damper on certain models. If a sensor becomes damaged or defective , it could cause the control board to turn off the fans and compressors which could result in higher than the normal fresh food or freezer temperatures. Individual manufacturers may provide specific data to test these sensors, dependent on the model being tested and could also include an error code to the electronic control board for certain models.
How do you test a temperature sensor in a refrigerator or thermistor with a multi-meter:
Begin by disconnecting the Samsung refrigerator. Then, take off the panel on the back to reveal the control board that is on top.
The thermistor(s) will be connected to the main control board. Then, remove the thermistor(s) from the appliance in order to test them.
Before testing them, you’ll need to immerse the thermistor(s) in freezing water for 5 mins in order to increase the temperature until 32 degrees F. The thermistor(s) will provide different readings at various temperatures, and the suggested ranges below are only applicable to thermistors that operate at temperatures of 32 degrees F.
You should see a reading of 16,600 Ohms 5 Percent if have probes attached to the terminals of your device and your multimeter set at Rx1.
If you notice a measurement that isn’t within this range you’ll need a replacement temperature sensor from Samsung or thermosistor.
Defrost Timer
The defrost-timer is an electromechanical timer. It is controlled by a set of contacts that regulate both the compressor and heater circuits. A timer can trigger an defrost process every 8-10 hours. It happens approximately once per day. The defrost timer should close the defrost sequence after 20 to 30 minutes and the compressor and fans will start over again.
How do you test a timer for refrigerator defrost with a multi-meter:
Find the defrost timer you need by disconnecting your appliance from its source of power. It can be found in the lower part of the refrigerator’s kickplate or inside the control panel of the Samsung refrigerator. It could be located behind the refrigerator’s back wall.
After you locate it, remove the defrost timer from the appliance to verify it.
Utilizing a multi-meter with the Rx1 setting and with one probe touching the common terminal (it should be labeled “3” or “C”) then, connect the other lead to the three remaining terminals, one at a time. The first pair of probes should yield a reading of or close to zero, which indicates continuity. A reading of zero or near zero could also be indicated by the other pair. The third pair must also be tested and the reading must read as if it was infinity.
These readings may not be recognized by you. You will need an replacement timer for Samsung.
Thermostats that Defrost
The Samsung safety thermostat, which is connected to the heater that defrosts, is utilized to stop the defrost process at a particular temperature. It is usually rated at 38 to 47 degrees Fahrenheit. If the thermostat is defective and remains in open circuit then the heater that is used to defrost the room will not be powered up and no defrosting will take place.
How do you test the thermostat to defrost fridges using an multimeter
Unplug your Samsung refrigerator and find your refrigerator’s thermostat for defrost. In models that have a freezer on top the thermostat could be situated beneath the floor of the refrigerator, or it could be located at the back of the freezer. The thermostat for defrost is found on the side of a side-by-side refrigerator.
Once you’ve found it, get it out and try it. You will have to remove any objects that may be blocking your path, such as the contents of the freezer, shelves for freezers as well as icemaker components, and the interior rear, back, or bottom panel.
Adjust your multimeter to the Rx1 setting. Set each probe on a thermostat wire. If the thermostat is at a low temperature, the multi-meter should read zero. 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 results presented here If you find that your results are different, you’ll need a replacement Samsung defrost thermostat.
Defrost Heater
The defrost heating device is the one that melts frost and freezing from evaporator coils. It is usually a wire filament enclosed in an aluminum or glass tube. It is possible to include more than one heater, dependent on the shape of the evaporator.
How do you test the heating element using a multimeter:
Before starting, be sure that your appliance is connected to the power source.
Locate your defrost heater. It can be located behind the back panel of your freezer section of your Samsung refrigerator, or underneath the floor of the freezer section. Defrost heaters are typically located beneath a refrigerator’s evaporator coils. You’ll need to clear of obstructions like the refrigerator’s contents, freezer shelves, icemaker pieces and also the rear, bottom, or bottom panels.
Before you test your heater’s defrost, you need to take it from your fridge. Two wires join to a defrost heater. The wires are connected via slip-on connectors. Grab the connectors with your solid grip and take them from the terminals. You might need some needle-nosed pliers to aid you. Be careful not to pull on the wires.
Test your multimeter the heater’s continuity. Set the tester’s leads on one terminal. This should give you a reading that is between zero and infinity.
If you are reading that is zero or even infinity, you’ll require an replacement Samsung heater for defrost..
Motor for condenser fans
Most modern frost-free Samsung refrigerators have a fan cooled condenser coil. It is usually located close to the compressor in the bottom of the refrigerator. The condenser fan moves air around the condenser coil to remove heat. The condenser fan motor may be defective if your refrigerator from Samsung is heating up faster than usual , and the compressor operates almost continuously. The condenser fan motor runs simultaneously with the evaporator motor and the compressor. If the fan motor is not running at all, the condenser won’t be able to expel all the heat. The compressor will run almost continuously
How do you inspect a refrigerator condenser fan motor:
Start by disconnecting the power source of the Samsung refrigerator. Then, take off the rear access panel and find the condenser fanmotor. It’s typically located on the bottom of the appliance.
Once you’ve found it, look over the fan to find obstructions or debris that might be stopping it from moving freely. Also, you should inspect the motor for indications of damage or wear..
