The main control board (also called the timer or circuit board) is the brain of your Amana washer. When it fails, you'll see error codes, unresponsive controls, stuck cycles, or a completely dead machine. Control board failures are one of the most common reasons an Amana washer stops working.
If your washer won't start, won't drain, or runs the same cycle repeatedly, the main control board is often the culprit. OEM Amana control boards come programmed for your specific model and are designed to match your washer's voltage and cycle logic exactly.
Enter your Amana model number above to find the exact control board for your washer. Amana washing machine control boards help ensure they fit your model when you verify the part number.
Control boards fail for several reasons: power surges, water damage near the board, normal wear over 7 to 10 years, or a manufacturing defect. If your home had a lightning strike or power outage right before the failure, a surge may have damaged the board. Water leaks that reach the board location are also common causes, especially in top-load Amana models where the board sits in the base.
The model number is printed on a sticker inside the washer tub (usually on the left side or back) or on the outer cabinet on the back panel. It's typically a 6 to 8 digit code starting with an 'N' (Amana Centennial or Bravos models). Write this number down before ordering — it ensures you get the exact board for your washer's cycle type and voltage.
Many DIYers can replace an Amana control board with basic tools and a screwdriver, though the location varies by model. Top-load Bravos machines usually have the board under the top panel — a straightforward 15-minute job. Centennial and older models may require removing the cabinet. Always unplug the washer and take a photo of the wire connections before unplugging them so you can reconnect them correctly to the new board.
Amana Centennial washers are older top-load models with simpler mechanical controls. Bravos models (especially Bravos XL) are newer, direct-drive top-loaders with electronic boards that control multiple cycles and speeds. The boards are not interchangeable — you'll need to match your exact model. If you have a Centennial, the control board will be simpler and less expensive than a Bravos board.
