Worth repairing?

Worth fixing

Can you do it yourself?

Easy

10 minutes to clean

Before you start

  • Unplug it before you touch anything inside.

What to check, in order

  1. Unplug the dryer

    At the wall.

  2. Clean the thermistor

    Wipe it gently with a dry cloth. A coating of lint is a common cause.

About this code

Unbranded and less common appliances don't publish one shared code list, so this page gives the most common meaning across makers. Your manual is the final word, and the model number that finds it is on a label inside the door, around the door frame or on the back.
