LE3 — Air circulation (blower) motor fault

LE3 indicates the air circulation / blower motor is not running at the expected speed. On heat-pump and hybrid models this is a separate motor from the drum drive motor; without airflow the cycle cannot proceed safely.

  4. Test the blower motor windings against the service-manual spec and replace if open.
  5. Reseat the blower motor harness at the main board.
  6. Reassemble and verify airflow on a Timed Dry cycle.
