Maytag Dryer Error Code no.U

The no.U code indicates an upper dryer motor sense circuit error on the control board. This means the board cannot properly read the signal from the upper dryer motor's sense circuit. As a result, the upper dryer cycles and its display are fully disabled until the code is manually cleared through the set-up mode.

A standard power reset is not the correct procedure for clearing this code. The no.U fault must be manually cleared through the dryer's set-up mode. If the underlying cause is still present, the code will return after clearing, indicating that further diagnostic work is needed.

Repair costs vary depending on the root cause. If the fault is due to a wiring or connector issue, repair costs are typically lower, often in the range of $75 to $150 for a service call and labor. If a control board replacement is needed, parts and labor combined can range from $200 to $400 or more depending on parts availability and local labor rates. A motor replacement would fall in a similar or higher cost range.

Start by entering the unit's set-up mode to view and manually clear the diagnostic code. If the code does not return, the fault may have been caused by a temporary electrical interference event. If the code comes back, inspect the wiring harness and connectors between the upper dryer motor and control board for damage or corrosion. Persistent faults may require replacing the control board or the upper dryer motor.

When the no.U code is active, the upper dryer section is automatically disabled by the control board, so the upper unit will not operate regardless. The lower dryer section, if present, may still function normally. You should address the fault before attempting to restore full operation of the upper dryer.
