Is this the same board as WH22X38697?

No - WH22X38697 is a different board for other GE models, such as the GFW550SSN. Its power wiring and connectors differ, so the two are not interchangeable.

What should I check before installing a new board?

Make sure the drain pump works - a failed pump will damage a new board. Also test the door lock and motor using the tech sheet under the lid, and check wiring for shorts.

My washer's pump runs on its own and the display is dead. What should I check?

Check the power supply, the door lock circuit and the wiring/connectors first. If those are good and the display still won't power up, the main board is the likely cause.

My old board has a 4-pin J503/J506 connector but this one has 5 pins. Will it work?

No - if the J503/J506 plug in your washer doesn't match this board's connector, don't install it. Contact us with your model number and photos of both boards.

Does this replace part WH22X36637?

Yes - this is GE's revised replacement for WH22X36637.

Does the board need to be programmed after installing?

Yes - it may need its personality setting selected. Instructions are included for the initial install or for changing the setting later.

After installing the board my washer shows H2O SUPPLY or tank low. What's wrong?

That usually points to water supply or pressure sensing, not the board. Check both valves are fully open, the inlet screens are clear, and the pressure hose isn't kinked, clogged or loose.

Is this a genuine OEM part?

Yes - this is a genuine OEM GE part.
