Maytag Dryer Error Code CCU error (motor feedback with door open)

CCU error

Maytag codesMaytag dryer codes

CCU error – CCU will send this error when the motor feedback circuit is sensing voltage with the door open or when the motor shouldn't be on. The control doesn't know if the relay is bad (stuck on), the relay drive circuit is bad (shorted causing the motor relay to stay on), or the relay feedback circuit is bad.

What CCU error (motor feedback with door open) means on a Maytag dryer

The CCU (Central Control Unit) error for motor feedback with door open is triggered when the control board detects voltage present on the motor feedback circuit while the door is open or while the motor is commanded off. Under normal operation, the motor relay should open when the door is unlatched or when a cycle ends, cutting power to the drive motor. When the CCU sees feedback voltage in those conditions, it flags this error because voltage at that point in the circuit indicates something is keeping the motor relay energized when it should not be.

The control board itself cannot distinguish between three possible failure points: a motor relay that is physically stuck in the closed position, a relay drive circuit that has developed a short and is continuously sending the activation signal to the relay, or a fault in the feedback circuit itself that is reporting false voltage. Each of these scenarios produces the same symptom from the CCU's perspective, which is unexpected motor circuit voltage, so further hands-on diagnosis is required to isolate the specific failure.

Because the motor could potentially run with the door open in some failure states, this error also carries a safety implication. The CCU is designed to detect and flag this condition precisely to prevent unintended drum rotation. Technicians should inspect the motor relay on the control board for signs of burning or contact fusion, check the relay drive transistor or circuit for shorts, and verify that the feedback wiring is intact and not shorting to a voltage source elsewhere in the circuit.

Common causes of CCU error (motor feedback with door open)

  1. 01

    Motor relay stuck closed on the CCU

    Part replacement

    The relay responsible for switching the drive motor on and off can fail with its contacts fused together, keeping the motor circuit energized regardless of commands. Inspect the relay on the control board for burn marks, discoloration, or physical damage.

  2. 02

    Shorted relay drive circuit

    Part replacement

    The transistor or drive circuit that sends the activation signal to the motor relay can develop an internal short, causing it to continuously energize the relay even when the CCU commands it off. This requires testing the drive circuit components on the control board.

  3. 03

    Faulty CCU control board

    Part replacement

    If both the relay and its drive circuit test correctly, the CCU itself may have an internal fault causing it to misread or misreport the motor feedback signal. Board-level failure requires replacement of the CCU.

  4. 04

    Wiring short in the motor feedback circuit

    Wiring / connection

    A chafed or pinched wire in the feedback circuit could be contacting a voltage source and sending a false signal to the CCU. Inspect the wiring harness between the motor relay and the control board for damage or contact with other conductors.

Frequently asked questions about CCU error (motor feedback with door open)

What does CCU error (motor feedback with door open) mean on a Maytag dryer?
This error means the dryer's Central Control Unit has detected voltage on the motor feedback circuit when the motor should be off, specifically when the door is open or the cycle has ended. The CCU cannot determine on its own whether the fault is a stuck motor relay, a shorted relay drive circuit, or a problem with the feedback wiring. It flags the error to prevent unintended drum operation and to alert you that hands-on diagnosis is needed.
Can I fix this error myself, or do I need a technician?
A knowledgeable DIYer can begin by inspecting the wiring harness connected to the motor relay for visible damage or shorts, which requires no parts replacement. However, diagnosing a failed relay, a shorted drive circuit, or a faulty CCU requires comfort with reading wiring diagrams and safely testing components on a control board. If you are not experienced with appliance electrical diagnosis, a qualified technician is the safer choice.
Is it safe to use my dryer when this error is displayed?
You should not attempt to run the dryer while this error is active. The fault indicates a potential condition where the drum motor circuit could be energized with the door open, which poses a risk of unexpected drum rotation. Disconnect power to the dryer until the root cause has been identified and repaired.
Will resetting the dryer clear this error code?
Resetting the dryer by disconnecting power may temporarily clear the error display, but the underlying fault will cause it to return. Because this error points to a hardware failure in the relay, drive circuit, or wiring rather than a software glitch, a reset alone will not resolve it. The faulty component must be identified and repaired or replaced.
How much does it typically cost to repair this error on a Maytag dryer?
Repair costs vary depending on which component has failed. If the issue is a wiring short, the cost may be relatively low, primarily covering labor. Replacing a faulty CCU control board is generally the most expensive repair in this fault scenario, with parts and labor costs potentially ranging from $150 to $400 or more depending on your location and the specific model. Getting a diagnostic visit from a technician first can help narrow down the exact part needed before committing to a repair.
