A Samsung dryer doesn’t start refers to a situation where the dryer fails to turn on or run when the start button is pressed. This issue can be caused by various factors, including a loose power cord connection, a partially closed door, an activated child lock function, a broken belt, a faulty broken belt switch, a malfunctioning motor circuit, or a tripped circuit breaker.

Troubleshooting these components and identifying the specific problem is essential to get the dryer back in working condition.  Once the faulty part is identified, it can be replaced to resolve the issue and ensure the dryer operates as expected.

  • Turn off the power to the dryer and unplug it from the wall.
  • Remove the top panel of the dryer to access the belt. Look for any signs of damage or misalignment.
  • Spin the drum by hand; the belt should be tight and spin along with the drum. If the belt is loose or broken, it may be the cause of the problem.

Step 4: Test the Motor Circuit

  • Access the control board at the back of the dryer.
  • Test the motor circuit by checking the resistance between the black and brown wires using a multimeter. A reading of around two ohms indicates a functioning circuit.
  • If you get an “OL” reading, it may indicate issues with the motor windings, broken belt switch, or thermal cutoff on the blower housing.

Step 5: Check the Broken Belt Switch

  • Locate the broken belt switch, which is connected to the idler arm.
  • Test the switch for continuity using a multimeter. A completed circuit should show a low resistance reading, while an “OL” reading indicates a faulty switch.

Step 6: Examine the Thermal Cutoff

Step 7: Verify the Motor

  • Test the motor by checking the resistance between the yellow and brown wires. A reading of around two ohms indicates a functioning motor.
  • If you get a different reading, the motor may need replacement.

Why Is My Samsung Dryer Not Spinning?


You turn on your Samsung dryer DV42H5200EW/A3, select the time dry option, hit start, and the drying icon blinks with an hourglass, but the time drops down, and the dryer shuts off before reaching zero. The drum isn’t spinning, and you suspect there’s an issue with the dryer’s belt or idler pulley.


Basic Checks:

    • Ensure the dryer is properly plugged in and receiving power from the circuit.
    • Verify that the door is completely closed and the door switch is functioning.
    • Check if the child lock feature is activated and deactivate it if necessary.
    • Avoid overloading the dryer with too many clothes.

Troubleshooting the Issue:

    • Remove the top lid of the dryer to access the belt.
    • Check if the drive belt is intact and properly positioned around the drum and pulleys.
    • Examine the idler pulley to see if it’s broken or damaged.
    • Inspect the switch near the idler pulley to ensure it’s not being activated, preventing the dryer from running.

Replacing the Idler Pulley:

    • Order an original Samsung OEM replacement part for the idler pulley.
    • Unplug the dryer and remove the rear vent to access the idler pulley.
    • Replace the old idler pulley with the new one, using the factory screw if it fits correctly.

Reassembling the Dryer:

    • Install the new idler pulley by positioning it around the belt and tucking it back into place.
    • Ensure the switch near the idler pulley is no longer activated.
    • Verify that the belt’s ribbed side is touching the drum, facing up.
    • Reconnect the vent and other components you may have removed.

Final Test:


By following these troubleshooting steps, you can identify the issue preventing your Samsung dryer from starting. Whether it’s a faulty door latch, power supply, belt, motor circuit, or thermal cutoff, you can now take the appropriate steps to fix it. If the problem persists or you are unsure about any of the steps, don’t hesitate to reach out to Samsung support for assistance.
