This guide will work for most Whirlpool dryers. This guide is written with a model WED87HED dryer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

There are six retaining clips securing the main board. Start at one end and work towards the other.
When you're handling the main board, wear an anti-static strap if possible, or regularly touch the exposed metal parts of the dryer to prevent electrostatic damage to the board.
Lift the board with one hand and use the other to release each clip with a spudger.
As you go, keep a gentle upward pull on the board so that the released clips don't snap back into place as you work.
Alternate sides of the board when releasing the clips.
