Refrigerators are important, but properly working ones are even more important. This is the reason different parts need regular maintenance to ensure they keep working for a long time. However, some people don’t pay enough attention and end up asking, “How to test ADC board Whirlpool?” If you are using a Whirlpool refrigerator and want to test the defrost control board, you have come to the right place!

Defrost Control Board – What Is It?

When it comes down to fixing issues, it is important to understand the parts and what their job is. So, the defrost control board is responsible for checking and monitoring the sensors that are responsible for testing the Whirlpool system for ice and activates the defrost mode (no, it doesn’t defrost ice within the refrigerator!). In fact, the defrost mode will melt the ice that generally builds up on the exterior refrigerant coils around the heat pump. It is actually important for optimizing refrigeration.

How To Test Your Whirlpool Adaptive Defrost Control Board

In this article, we are sharing two ways of learning how to test the whirlpool adaptive defrost control board. For more details, you can check out the information below;

The 1st Method

In the first method, the steps are pretty simple, and you will be able to test the system, such as;

  • Switch off the thermostat for fifteen seconds
  • Switch on the thermostat for fifteen seconds
  • Switch off the thermostat for fifteen seconds
  • Switch on the thermostat for fifteen seconds
  • Switch off the thermostat for fifteen seconds
  • Switch on the thermostat for fifteen seconds
  • Now, finally, switch off the thermostat

When you follow these steps, the system will switch on in less than ten seconds. You need to know that test mode is likely to terminate whenever the bimetal opens up. So, if the Whirlpool refrigerator is already under the defrosting function, the refrigerator’s test mode can be eliminated by just taking out the main plug and wait for thirty seconds. As a result, the refrigerator will switch on the cooling mode because the thermostat is switched off.

The 2nd Method

If the first method helps test the ADC board, but the defrost mode is still not working, you can check out the method for testing and (hopefully) get the defrost mode back on track.

First of all, switch off the refrigerator from the main electricity outlet for around thirty seconds. Now switch off the thermostat. Then, wait for up to ten seconds, the ADC board will switch on the defrosting heater

On the other hand, the refrigerator is unable to switch on the defrost mode, the problem isn’t with the board, and you might need to get the damaged bimetal checked. Keep in mind that the ADC board will switch on the Whirlpool refrigerator’s test mode only when the bimetal is switched off. Similarly, when the ADC board senses an open bimetal, it will switch on the cooling mode within ten seconds.

At this point, we do want to add a hint. So, when the refrigerator goes into test mode, keep in mind that the relay on the ADC board should switch off, and the refrigerator’s defrost heater will turn on. For this purpose, you need to listen to the clicking sound in the relay. In case you hear the clicking sound once, the continuity should be checked. On the other hand, if you listen to the clicking sound twice, check for an open bimetal.

Signs That ADC Board Is Damaged Or Not Working Properly

1. Unable To Defrost

Did you check that the heat pump? Can you see some ice on the surface of the heat pump? For the most part, thick ice will build upon the heat pump when the ADC board is not working properly or if it is switched off. In addition to the board, it could also mean damage to a few sensors.

2. Constantly Running Unit

Nope, not literal running! When the exterior unit keeps running, it won’t be able to absorb heat from the environment, and it could be because the ADC board is damaged. However, it could be because of damaged sensors, but your first hint should be checking the board.

To summarize, these are some methods you can follow for testing the ADC board of the Whirlpool refrigerator. For more help, you can ask for Whirlpool customer support.
