Maytag Dryer Error Code d12

The d12 code on a Maytag dryer indicates a motor sense error on the control board. It means the board did not receive the expected signal from the motor sense circuit, which can be caused by an internal board fault or by interference on the power line. When this code is active, all cycles and the customer display are disabled until the code is manually cleared through the dryer's set-up mode.

Start by entering set-up mode on the dryer and manually clearing the d12 code. If the dryer runs normally after clearing and the code does not return, the fault was likely caused by a temporary power line event. If the code comes back, inspect the wiring harness connections at the motor and control board, evaluate the quality of the dryer's electrical supply, and consider testing or replacing the control board if no other cause is found.

Repair costs depend on the root cause. If the issue is a one-time power event and clearing the code resolves it, there may be no parts cost at all. If the control board needs replacement, parts and labor typically range from $150 to $400 depending on the specific model and local labor rates. Wiring repairs or motor replacement would fall within a similar or higher range depending on the extent of the damage.

A standard power reset, such as unplugging the dryer, will not clear the d12 code on its own. The code must be manually cleared by entering the dryer's set-up mode and resetting the fault through the diagnostic interface. If the code reappears after being cleared, there is an underlying issue with the control board or the electrical supply that needs to be addressed.

The dryer will not allow you to run cycles while the d12 code is active, as all cycles and the display are disabled until the code is cleared. This means the machine is protecting itself from operating in an uncertain condition. You should clear the code before attempting to use the dryer, and if the code returns repeatedly, have the unit inspected before continued use.
