    Step 1

    1. Unplug the dryer from the wall outlet to completely disconnect the power.

  4. 4

    Step 4

    4. Visually inspect the entire length of the dryer's power cord. Look for any signs of damage, such as fraying, burn marks, or exposed wires.

  5. 5

    5. If the error code remains after checking the external power supply, the issue is with the internal control module, which manages the dryer's electrical functions.

  6. 6

    Step 6

    6. Replacing the control module involves complex wiring and a risk of electrical shock. This repair should be performed by a qualified appliance technician.

Unplug the dryer before touching the lint housing, rear vent, lower service area, or any wiring. Clean the lint screen, moisture sensor bars, condenser area if equipped, and the full vent path so airflow problems do not imitate part failures. Run a short timed cycle with a light load and note whether the fault appears immediately, after heating starts, or near the end of the cycle. If the fault returns with clean airflow, inspect the part categories below using the full model number from the dryer tag. Stop repeated test cycles if you smell heat, see moisture near electrical areas, or hear grinding from the drum drive. Verified Compatible Alternatives:0066122900631326481590 Still Not Working?
