Maytag Dryer Error Code CCU error (motor feedback - stacked)

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.

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.

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.

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.

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.
