Maytag Dryer Error Code ACCU

Dryer motor control circuit error

Maytag codesMaytag dryer codes

Dryer motor control circuit error – the control cannot determine if the motor relay is stuck on, the motor relay drive circuit is shorted causing the relay to stay on, or the motor relay feedback circuit is bad.

What ACCU means on a Maytag dryer

The ACCU error code on a Maytag dryer indicates a motor control circuit fault in which the main control board cannot accurately determine the state of the motor relay. Specifically, the control is unable to distinguish between three related failure conditions: the motor relay being mechanically stuck in the closed (on) position, the motor relay drive circuit having a short that holds the relay energized, or the motor relay feedback circuit providing incorrect or no signal back to the control board. Because the control cannot verify whether the motor is actually running or stopped, it treats the situation as a safety-critical fault and locks out normal operation.

The motor relay is responsible for switching power to the drive motor on and off based on commands from the control board. When the control sends a stop command but the feedback circuit reports the relay is still closed, or when the relay drive circuit has a short that bypasses normal control logic, the board cannot confirm the motor will respond correctly. This ambiguity creates a condition where the dryer could potentially run unexpectedly or fail to stop, which is why all cycle selection and price display functions are disabled until the code is manually cleared. The fault points to either a failed relay on the control board, a wiring issue in the drive or feedback circuit, or a defective control board itself.

Common causes of ACCU

  1. 01

    Failed motor relay on the control board

    Part replacement

    The relay itself can fail mechanically with welded contacts that remain closed, or electrically in a way that makes it appear stuck on. A failed relay typically requires replacing the main control board since the relay is integrated into it.

  2. 02

    Shorted motor relay drive circuit

    Wiring / connection

    A short in the wiring or circuit traces that drive the motor relay can hold it in the energized position regardless of control commands. Inspect the wiring harness between the control board and motor relay for damaged insulation, pinched wires, or burn marks.

  3. 03

    Faulty motor relay feedback circuit

    Wiring / connection

    If the feedback circuit that reports relay status back to the control board is damaged or broken, the control board receives inaccurate or no signal and triggers the ACCU fault. Check the associated wiring and connectors for corrosion or loose connections.

  4. 04

    Defective main control board

    Part replacement

    Internal failures in the control board beyond just the relay, such as damaged circuit traces, burned components, or failed transistors in the drive circuit, can produce this code. Visual inspection may reveal burn marks or damaged components on the board.

  5. 05

    Loose or corroded wiring connections

    Wiring / connection

    Poor connections at the control board harness connectors can disrupt both the drive signal and the feedback signal, causing the control to misread the relay state. Reseating and inspecting all connectors related to the motor circuit is a low-cost first step.

Frequently asked questions about ACCU

What does ACCU mean on a Maytag dryer?
The ACCU code on a Maytag dryer indicates a motor control circuit error. The control board cannot determine whether the motor relay is stuck on, whether a short in the relay drive circuit is keeping it energized, or whether the relay feedback circuit is reporting correctly. As a result, the dryer disables all cycle and display functions until the code is manually cleared.
Will resetting the dryer clear the ACCU error code?
The ACCU code does not clear automatically on a Maytag dryer. It must be manually cleared through the diagnostic process. Even after clearing, if the underlying fault in the motor relay circuit, drive circuit, or feedback circuit is not repaired, the code will return when the dryer attempts to operate.
Is it safe to use my Maytag dryer when the ACCU code is displayed?
No, you should not attempt to use the dryer while the ACCU code is active. The fault indicates the control board cannot verify the motor relay will respond correctly to stop commands, which means the motor could potentially run unexpectedly. The dryer disables itself for this reason, and operation should not be restored until the circuit fault is diagnosed and repaired.
How do I fix the ACCU error code on a Maytag dryer?
Diagnosing the ACCU code requires checking the motor relay on the control board, the relay drive circuit wiring, and the relay feedback circuit for shorts, damaged wiring, or loose connections. Start by inspecting the wiring harness connectors at the control board for corrosion or poor contact. If wiring checks out, the control board itself is likely the faulty component and will need to be replaced.
How much does it cost to repair the ACCU error code on a Maytag dryer?
Repair costs depend on which component is at fault. If the issue is a wiring connection, costs may be minimal. If the main control board needs to be replaced, parts alone can range from roughly 100 to 300 dollars depending on the model, with additional labor costs if a technician is hired. Getting a diagnostic assessment before purchasing parts is recommended to avoid unnecessary expenses.
