WH22X37840 Genuine OEM GE Washer Main Control Board
The WH22X37840 is a genuine GE OEM main control board for GE and Profile UltraFresh front-load washers. This board is the washer's central processor — it reads every button press and cycle selection, drives the motor and inverter, opens and closes the water valves, runs the drain pump, and continuously monitors water level through an integrated water pressure switch built into the board itself. Because so many functions route through this single board, a failing control board can produce almost any symptom: a washer that won't power on, won't start a cycle, stalls partway through, fails to fill or drain, or runs a cycle that doesn't match what was selected on the display.
This board revises and supersedes WH22X36637, and also replaces WH22X29532, WH22X30898, WH22X32057, WH22X32457, WH22X34659, WH22X35517, WH22X36857, and WH22X37839. As a genuine OEM part, the WH22X37840 is manufactured by GE to factory specifications — guaranteed fit, materials, and performance. Important: this board is not universal across GE's front-load lineup. It must be matched to your specific model and, after installation, programmed with the correct "personality" code for your washer before it will operate properly.
Quick Answer
The WH22X37840 Genuine OEM GE Washer Main Control Board fixes GE and Profile UltraFresh front-load washers that won't power on, won't start, stall mid-cycle, fail to fill or drain, run the wrong cycle, or have an unresponsive control panel. Genuine OEM, includes an integrated water pressure switch. Revises WH22X36637; also replaces WH22X29532, WH22X30898, WH22X32057, WH22X32457, WH22X34659, WH22X35517, WH22X36857, WH22X37839. Fits GFW650S, GFW850S, PFW870S, and PFW950S platforms. Requires programming a model-specific "personality" code after install, and the drain pump must be confirmed good before installing — a failed pump can damage a new board.

Installation Notes
Frequently Asked Questions
Do I really need to program the board after installing it?
Yes — this is not optional. The WH22X37840 is shared across several GE and Profile washer models, and it needs to be told which specific model it's installed in through a "personality" code before it will run correctly. Skipping this step, or entering the wrong code, will leave the washer behaving unpredictably even though the board itself is functioning normally. GE provides official programming instructions (publication 99-3000289) with the button sequence for your model — follow those closely rather than guessing.
Why does the listing say to check the drain pump before installing this board?
Because on this platform, a failing or clogged drain pump can feed electrical strain back into the control board that damages it over time — the same failure that likely killed your original board. If you install a new board without addressing a bad drain pump, there's a real risk of burning out the replacement as well. Before installing, run the pump through a diagnostic or physically inspect it for clogs, a seized impeller, or electrical failure, and address any issues found there first.
My washer won't power on at all. Is this the right part?
It's a strong candidate, but rule out the obvious first: confirm the outlet has power, check that the washer's power cord and connection are intact, and check the home's circuit breaker or a blown fuse. If those are all fine and the washer still shows zero signs of life — no lights, no display, no response to any button — the main control board has very likely failed and this board is the correct replacement.
What's the difference between WH22X37840 and WH22X36637?
They are the same board across production revisions. WH22X36637 was the prior GE part number and WH22X37840 is the current number that supersedes it. If your washer's parts diagram shows WH22X36637 or any of the older numbers (WH22X29532, WH22X30898, WH22X32057, WH22X32457, WH22X34659, WH22X35517), this listing is the correct replacement — it installs and programs the same way.
Does this board include the water pressure switch?
Yes. The water pressure switch that monitors fill level is integrated directly into this control board and is not available as a separate part per GE. If your washer's issue turns out to be water-level detection specifically — overfilling, underfilling, or an error related to water level — this board is the correct and only OEM fix, since the pressure switch cannot be replaced on its own.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by GE to factory specifications — guaranteed fit, materials, and performance. It carries the same firmware, relay switching, integrated water pressure switch, and harness layout as the control board originally installed in your washer, and it is the officially supported replacement for your model once the correct personality code is programmed.
