Here are the general steps to follow if you suspect an issue with the control board:

Step 1: Diagnosis: Begin by identifying the specific problem with the control board. Confirm that the control board is indeed the issue by checking for common symptoms like a non-responsive control panel, error codes, or no heat.

Step 2: Check for Loose Connections: Sometimes, loose or disconnected wires can cause control board issues. Inspect the wiring harnesses and connectors for any disconnections or damage. Reconnect or replace damaged wires as needed.

Step 3: Reset the Control Board: Try resetting the control board by unplugging the dryer for several minutes (typically 10-15 minutes) and then plugging it back in. This can sometimes clear minor glitches.

Step 4: Check for Burnt Components: Carefully inspect the control board for any visible signs of damage, such as burnt or scorched components. If you find any, it’s a clear indication that the control board needs replacement.

Step 5: Replace the Control Board:

If you’ve confirmed that the control board is faulty and needs replacement, follow these steps:

  • Order a replacement control board that is compatible with your Samsung dryer model. Make sure to have the correct part number.
  • Unplug the dryer from the power source and disconnect it from the gas supply if applicable.
  • Remove the dryer’s top panel, front panel, or rear panel (depending on the model) to access the control board.
  • Carefully disconnect the wiring harnesses from the old control board.
  • Remove any screws or mounting brackets securing the control board in place.
  • Install the new control board, securing it with screws or brackets.
  • Reconnect the wiring harnesses to the new control board.
  • Reassemble the dryer’s panels in reverse order of removal.
  • Plug the dryer back in and test its operation.

Step 6: Test the Dryer: After replacing the control board, test the dryer to ensure that the issues have been resolved. Check if the control panel responds, the dryer produces heat, and there are no error codes.

Fixing Error Codes On The Samsung Dryer Control Board

Fixing error codes on a Samsung dryer control board typically involves identifying the specific error code, diagnosing the underlying issue, and taking appropriate steps to resolve it. Here’s a general guide to help you address error codes on your Samsung dryer:

Step 1: Identify the Error Code: When an error code appears on the control panel, take note of the code or error message displayed. The error code will help you pinpoint the problem.

Step 2: Consult the User Manual: Refer to your dryer’s user manual or technical documentation. Most manuals include a list of error codes along with explanations of what each code means and recommended actions to take.

Step 3: Power Cycle the Dryer: Sometimes, error codes can be triggered by temporary glitches. Unplug the dryer from the power source and leave it unplugged for about 10-15 minutes. Then, plug it back in and see if the error code clears. If the error persists, proceed with further troubleshooting.

Step 4: Check for Simple Issues: Before complex troubleshooting, inspect simple issues that could trigger error codes, such as:

  • Ensure the dryer door is properly closed and latched.
  • Verify that the lint filter is clean and installed correctly.
  • Confirm that the exhaust vent is not blocked or restricted.

Step 5: Restart or Cancel the Current Cycle: If the error code occurs during a drying cycle, try pressing the “Pause” or “Cancel” button to stop the cycle. Then, restart the dryer and see if the error code reappears.

Step 6: Inspect Sensors and Components: Some error codes may relate to specific sensors or components. For example, a common error code is HE (Heating Element). In such cases, you may need to check the heating element for continuity or the moisture sensor for cleanliness.

Where is the start switch on the Samsung dryer?

The location of the start switch on a Samsung dryer can vary depending on the model. In most Samsung dryers, you’ll find the start switch on the control panel, often labeled as “Start” or represented by a play/pause symbol. It’s the button you press to begin a drying cycle.

Why is my Samsung dryer squeaking?

A squeaking noise in a Samsung dryer can be caused by several factors:

  • Worn Drum Rollers: Over time, the drum support rollers that help the drum rotate can wear out, leading to squeaking. They may need replacement.
  • Belt Issues: If the dryer belt is damaged or worn, it can create a squeaking sound as it moves. Consider inspecting and possibly replacing the dryer belt.
  • Idler Pulley: The idler pulley, which maintains tension on the belt, can also cause squeaking if it’s worn or damaged. Replacement may be necessary.
  • Foreign Objects: Check for any foreign objects, like coins or buttons, that may be caught in the drum’s fins. Remove them to eliminate the noise.

What does a “FIR” check mean on a Samsung dryer?

FIR” is not a standard error code on Samsung dryers. Samsung dryers typically display alphanumeric error codes that correspond to specific issues. If you see “FIR” on your dryer’s display, it might be a non-standard code or a display issue. Consult your dryer’s user manual or contact Samsung customer support for guidance on troubleshooting and addressing this error.

If you suspect an issue with the thermostat, it’s advisable to consult your dryer’s user manual for specific instructions on accessing and replacing it or seek assistance from a professional technician.


Troubleshooting issues with a Samsung dryer control board requires a systematic approach to identify and resolve problems efficiently. By consulting the user manual for error code explanations, checking power sources, performing basic checks, and exploring possible component issues, many common problems can be resolved.
