You may have encountered an error code indicating troubleshooting of the freeze-thaw timer. There are now several steps you can take to fix this problem. We will talk about this shortly. Defrost timer defective When it deteriorates and therefore stops in cooling mode, uneven frost forms on the evaporator coils, which reduces airflow. Or, if it stops at the defrost option, it will melt all the frost and will not revert to the chill sequence.

Commercial refrigeration systems are required to maintain high concentrations of food and / or pharmaceutical products in research environments. Therefore, errors in cooling are costly in terms of product and work loss.

Before you decide to remove and replace the defrost timer, it is advised to fix the timer so that you are definitely having a problem. Before you can check the timer, you need to know how the defrost timer works.
Setting a timer to defrost a refrigerator is often surprisingly easy. Follow the tips below to test your defrost timer successfully.
How can I remember to replace the defrost timer automatically?
What should I do if my freezer is not defrosting?
There is no real way to know if you have a defrost timer should be replaced without checking simple circuits. However, if your refrigerator is showing these symptoms, replacing the defrost timer may fix the refrigerator problems.

Basic Principles Of Defrost Timer
How do I reset my defrost timer?
To reset the refrigerator’s defrost timer, Tepte simply tells you to find the circular degree on the timer and turn it counterclockwise with a flat-blade screwdriver. This should help you turn around until the fan stops, which means your refrigerator has reset the defrost button.
How do I know if my defrost timer is bad?
The defrost timer has four contacts, labeled 1 through 4. Each contact has a different function for timer-related operation.
Where is the defrost timer on a whirlpool refrigerator?
Pin 1: The main function of the input is connected to pin 1. Pin 2: When defrosting in mode, the power supply (pin 1) is connected to pin 2, which will normally activate defrosting mode. Most defrost timers remain in defrost mode for 30 minutes. Pin 3: This is your ground / neutral wire. Only three contacts are separated from the rest. Pin 4: When the timer is not close to defrost mode, the power supply (pin 1) will be connected to pin 4, which will activate the inverter and the fan. Most timers remain in this mode for up to 10 hours.
To check if the defrost mode is working, apply voltage to pin 1. When the power is on, you can measure the voltage on pin 2.
After 30 minutes, the timer should turn on the compressor and / or fan. You will see that timer deflationFreeze works if you measure the voltage at pin 4 as soon as the timer is not in defrost mode.
The compressor and fan spindle must be on for 10 hours (or as long as you want the correct defrost timer to work). After 10 hours, the defrost timer switches back to the participation contact and activates the defrost.
Check Defrost Timer
You can test the defrost timer with the test resistor in the circuits when the timer is in any mode.
When the defrost timer is in defrost mode, you must measure the open circuit between pin 12 (main power input) and pin 4.
If the defrost time has exceeded the defrost mode, everyone should measure the distance between pin 2 (main power input) and pin 2 and open the circuit.
You will also have to check for a long time if the engine is running. You can do this by adding a power supply to the timer while the timer is in defrost mode. You want to make sure that the engine is l is ahead of the timer. For more information, watch the video below.
