Maytag Dryer Error Code dM

The dM code indicates a motor control circuit error. The control board has detected a fault in the motor relay circuit but cannot determine whether the relay is stuck on, the relay drive circuit is shorted, or the relay feedback circuit is bad. As a safety response, the dryer disables all cycle selections and display functions until the code is manually cleared.

No. The dryer disables cycle and display functions specifically to prevent the motor from operating in an uncontrolled state. Running the dryer with a motor relay fault could lead to overheating or further component damage. The dryer should remain out of service until the fault is properly diagnosed and repaired.

Repair costs depend on which component has failed. If the problem is a damaged wiring harness or connector, costs may be relatively low, generally in the range of $50 to $150 for parts and labor. If the main control board requires replacement, total repair costs including labor typically range from $200 to $450 depending on the specific model and local labor rates.

Some basic checks are within reach for a knowledgeable DIYer, including inspecting wiring harness connectors between the control board and motor for corrosion or damage. However, if the fault lies within the relay drive or feedback circuit on the control board, board replacement is typically required and is best handled by a qualified technician. Attempting to bypass or ignore the fault is not recommended.

The dM code must be cleared manually through the diagnostic mode rather than through a simple power cycle. Even after clearing the code, if the underlying fault in the motor relay circuit is not corrected, the code will return when the control detects the condition again. Clearing the code is a diagnostic step, not a repair.
