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.
