Use this guide to replace the main board a.k.a. Cycle Control Unit (CCU) on your Whirlpool dryer. The main board is the "brain" of the dryer. When it fails, the dryer will operate erratically or not operate at all. 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.

Safety Precautions

Before you begin your repair, unplug your dryer.
Your power cord may have four prongs rather than three. The additional prong is a ground connection.

Unfasten the top panel

Throughout this guide, keep track of each screw and reinstall it exactly where it came from.
Use a nut driver to remove the screws securing the top panel to the rear panel bracket.

Remove the top panel

Grasp the top and slide it 1/2 to 1 inch toward the rear of the machine.

Step 4

Lift the top panel upward to separate it from the chassis.
Remove the top panel from the machine.

Disconnect the Main Board

Disconnect all the wires from the main board.

Step 6

Continue disconnecting the main board.

Step 7

Finish disconnecting the wires from the main board.

Unfasten the main board cover

Using a flat head screwdriver or a spudger, release the cover clips.

Remove the main board cover

Lift the cover to release the tabs on the opposite side of the main board housing.
Remove the cover.

Release the main board

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.

Step 11

Release the remaining clips until the board is completely separated from its housing.

Remove the main board

Remove the main board from its housing.
