A class suit was filed and then later on won against Maytag in 2004 due to the high failure rate of the wax motor used in the door lock mechanism of their Neptune Front Load Washers. The wax motor is used to activate the door lock switch by extending its shaft when a voltage from the machine control is applied across its terminals. Its failure then leads to the breaking down of components in the expensive machine control board. This is the fact that angered the customers which lead to the filing of the class suit.
Maytag Neptune defective door latch wax motor update by: Anonymous
The older Neptunes, such as the 2000 Stackers, MAH3000, MAH4000 and the MAH5500A series had some issues which I am sure Maytag has corrected these issues in the newer machines...
There are thousands who have been burnt by the door latch wax motor failure. What happens is the machine will stop spinning because the door latch will fail to lock. Deep inside it is caused by the mechanism that locks the door. The wax motor will draw too much current and damage the control board by burning a resistor (R11) and a triac (Q6).
However, if Neptune owners know to replace the door latch wax motor they can prevent the control board failure from happening. Please tell everyone you know about this important fact.
The older Neptune’s also have a couple additional issues such as the moldy door boot and the reliability of the motor / motor control board. All three of these issues were involved in the class action lawsuit a couple of years ago. See http://www.neptunewaxmotor.com for more Neptune information.
