In today’s world of advanced technology, troubleshooting your appliances at home has become increasingly convenient. One such appliance is your LG dryer. When it starts acting up, you might need to test the control board to identify the issue. This comprehensive guide will help you understand how to test your LG dryer control board and what steps to take if it’s faulty.
To test an LG dryer control board, first unplug the dryer for safety. Remove the top panel of the dryer to access the control board. Unplug all the wire harnesses connected to the board. Use a multimeter to check for continuity, voltage, and resistance in various parts of the board. If you find any signs of damage, such as burn marks or shorted-out areas, the control board might be faulty and need replacement.
Recognizing the Signs of a Problem
Before you start testing the control board, it’s important to recognize the signs that indicate a problem. These include:
- The dryer not starting even though the drum light is on
- The dryer’s buttons and knobs on the display board seem to work properly, but the dryer does not start
- The main control board motor relay gets stuck in the ON position
In such cases, it is essential to troubleshoot the issue and, if necessary, replace the control board to resolve the problem.

Tools Required for Testing
To test the LG dryer control board, you will need a multimeter to check for continuity, voltage, and resistance in various parts of the control board. A screwdriver is needed to remove the screws holding the control board in place and to access the board for testing and repair. If you find that the control board is faulty, you may need to replace it or specific components on the board. Make sure to have the correct replacement parts on hand.
Steps to Test the LG Dryer Control Board
To accurately test the LG dryer control board, follow these steps:
- Unplug the dryer and ensure it is cool before starting the test.
- Remove the top lid of the dryer by unthreading the two screws in the back.
- Remove the two screws from the back panel to access the main control board.
- Unplug all the wire harnesses connected to the control board.
- Visually inspect the control board for any signs of damage, such as burn marks or shorted-out areas.
Interpreting the Test Results
Once the test is completed, you need to interpret the results. Monitor the flow sense display on the control panel during the test cycle. If no bars are displayed when the cycle ends, the exhaust system is okay. If the exhaust system is severely restricted, the display will show 4 bars, and you should have your exhaust system checked immediately before continuing use.
