Amana Washer Control Board Reset Guide After Power... | appliancefaults.com

Technical Background:

The washer's main control unit (MCU) manages all washer functions. It receives power from a 120V AC supply, which is stepped down to DC voltages (typically 5V and 12V) by an internal power supply. A power outage can cause voltage fluctuations that damage the MCU or corrupt its memory. Loose wiring can interrupt the voltage path.

Symptoms:

The Amana washer is unresponsive after a power outage. The control panel may be blank, or it might display an error code. The washer does not start when the START button is pressed. The door may be locked and unable to open.

Possible Causes:

Voltage surge or spike during the power outage.
Corrupted memory within the control board’s MCU.
Loose wiring connections to the control board.
Failure of the internal power supply on the control board.
Software glitch requiring a reset.
Damaged surge protection components within the washer.

Solution:

1

Disconnect the washer from the power outlet.
2

Locate the washer's control board (usually behind the control panel). Use a 1/4-inch nut driver to remove screws.
3

Inspect the wiring harness connected to the control board. Ensure all connections are secure.
4

Check the voltage at the power input to the control board. With the washer plugged in, use a multimeter to confirm 120V AC is present at the appropriate terminals.
5

Perform a hard reset: Unplug the washer for 5 minutes. Then, press and hold the START button for 10 seconds while plugging the washer back in. This might clear the error.
6

If the reset doesn't work, consider replacing the control board. Order a replacement board matching the washer's model number.
7

After replacing the board, run a diagnostic cycle to confirm proper operation. Consult the service manual for the diagnostic procedure.

Safety Warning:

Disconnect power to the washer before performing any repairs. Lockout/Tagout (LOTO) procedures must be followed. High voltage is present when the washer is plugged in. Use extreme caution.

Prevention:

Install a surge protector at the outlet where the washer is plugged in. Periodically inspect the wiring connections to the control board for any signs of looseness or corrosion. Avoid overloading the electrical circuit.

Expert Tip:

Some Amana washers have a service mode. While unplugged, press and hold the START and POWER buttons simultaneously, then plug the washer back in while holding the buttons. Release the buttons after 5 seconds. This might unlock additional diagnostic features and reset options (consult the service manual).

You can usually find the service manual online by searching for the model number followed by 'service manual'. AppliancePartsPros.com or similar sites often have them. You might also find it on the manufacturer's website.

•How do I identify the correct replacement control board for my specific washer model?

The best way is to use the model number of your washer to search for the correct part on appliance parts websites. The part number is usually printed on a sticker or label on the control board itself. Verify it matches the recommended replacement part.

•What are the common symptoms of a failing control board power supply?

Common symptoms include intermittent operation, random error codes, lights flickering on the control panel, and the washer not powering on at all. Voltage readings at the board will be erratic or outside of the specified ranges.
