What CCU error (motor feedback - stacked) means on a Maytag dryer

The CCU error for motor feedback on a Maytag stacked dryer unit indicates that the Central Control Unit is detecting voltage on the motor feedback circuit at a time when the motor should not be running. This occurs either when the door is open or during any other condition in which the motor relay should be in the off position. The CCU continuously monitors the feedback circuit to confirm that relay states match commanded states, and when it senses voltage where none should exist, it flags this fault to prevent uncontrolled motor operation.

The three primary hardware causes are a relay that has stuck in the closed position, a short within the relay drive circuit, or a failure in the relay feedback circuit itself. A stuck relay physically cannot open, meaning the motor circuit remains energized regardless of the control board's commands. A shorted relay drive circuit can force the relay into a closed state even without an intentional drive signal. A faulty feedback circuit may misreport the relay's actual state, causing the CCU to log the error even if the relay is functioning correctly.

Because this fault involves the motor relay and its associated drive and feedback circuitry, diagnosis should focus on the CCU board and the wiring harness connecting it to the motor relay. Inspecting relay contacts for welding or carbon buildup, checking drive circuit continuity, and testing feedback circuit wiring for shorts to voltage are the key diagnostic steps. In most cases, the CCU board itself must be replaced if the relay or drive circuitry is internally damaged, as these components are typically not serviceable separately on stacked units.

Common causes of CCU error (motor feedback - stacked)

  1. 01

    Stuck motor relay on the CCU board

    Part replacement

    The relay responsible for controlling motor power can fail in the closed position, keeping the motor circuit energized even when the control board commands it off. This is identified by the motor attempting to run with the door open or the relay contacts showing continuity when they should be open.

  2. 02

    Shorted relay drive circuit

    Part replacement

    A short within the circuit that drives the motor relay can force the relay to remain closed without an intentional control signal. Inspecting the wiring harness and board traces between the CCU and the relay for signs of a short to voltage will help confirm this cause.

  3. 03

    Faulty relay feedback circuit

    Wiring / connection

    The feedback circuit reports relay status back to the CCU, and if this circuit develops a fault or picks up stray voltage, the CCU will log the error even if the relay itself is operating correctly. Checking the feedback wiring for insulation damage or shorts is the primary diagnostic step.

  4. 04

    Damaged or corroded wiring harness connections

    Wiring / connection

    Corrosion or damage at the connectors between the CCU and the motor relay assembly can cause erroneous voltage readings on the feedback circuit. Inspecting and reseating harness connectors near the control board can rule out this cause.

  5. 05

    Failed CCU board

    Part replacement

    If internal board components beyond the relay itself have failed, including drive transistors or feedback sensing components, the entire CCU board will need to be replaced. This is typically the conclusion after ruling out wiring and relay contact issues.

Frequently asked questions about CCU error (motor feedback - stacked)

What does CCU error (motor feedback - stacked) mean on a Maytag dryer?
This error means the Central Control Unit has detected voltage on the motor feedback circuit when the motor should be off, such as when the door is open. It indicates a problem with the motor relay, the relay drive circuit, or the relay feedback circuit. The control board cannot confirm that the motor relay is actually in the off position, which triggers the fault. This is a safety-relevant error because it suggests the motor may be running or capable of running when it should not be.
Can I fix the CCU motor feedback error on my Maytag dryer myself?
Some portions of the diagnosis, such as inspecting wiring harness connectors for corrosion or damage, can be performed by a knowledgeable DIYer with the power disconnected. However, confirming whether the motor relay is stuck or whether the drive and feedback circuits are shorted requires electrical testing with a multimeter and familiarity with control board circuitry. If the CCU board itself is found to be faulty, replacing the board is straightforward but identifying the root cause first is important to avoid replacing parts unnecessarily.
Is it safe to use my Maytag dryer when this error is displayed?
You should not continue using the dryer while this error is active. The fault indicates the motor relay may be stuck closed, which could allow the motor to run under unsafe conditions such as when the door is open. Continuing to operate the appliance risks injury and potential further damage to the control board and motor components. Disconnect power until the fault has been properly diagnosed and repaired.
How much does it cost to repair the CCU motor feedback error on a Maytag dryer?
Repair costs depend on which component has failed. If the issue is a wiring connection, costs may be limited to a service call fee in the range of $75 to $150. If the CCU board requires replacement, parts and labor together typically range from $200 to $400 or more depending on the specific model and local labor rates. Getting a diagnostic assessment before authorizing parts replacement is the best way to avoid unnecessary expense.
Will resetting the Maytag dryer clear the CCU motor feedback error?
Disconnecting power briefly may temporarily clear the error code from the display, but it will not resolve the underlying hardware fault. If the relay is stuck, the drive circuit is shorted, or the feedback circuit is faulty, the error will return as soon as the dryer attempts to operate. A reset is useful for confirming the fault is persistent and not a one-time communication glitch, but it is not a repair solution for this particular error.
