Take careful note of the belt path before proceeding.

Be careful during this procedure! The idler arm is under spring tension and may pinch you, or it could damage the belt switch if the arm is allowed to snap down.

Push the idler arm (the metal upside-down "L") up to relieve the tension on the drive belt.

Remove the belt from the motor pulley.

Gently lower the idler arm until it rests parallel to the dryer floor.

During reassembly, refer to your notes or the belt path link to rethread the drive belt.
