The R11 burns because the wax motor jams. If the R11 is burnt, it is time for a new circuit board. These are availible on line from the manufacture or at local appliance stores ( I use first source parts). To forwarn you, circuit boards can be pricy. Once you have the circuit board, it is just a case of unplugging on connection at a time and plugging it back in to the new board. To replace your wax motor, you firs must take the 4 screws out of the door frame to the right and left as you open the door. Once you do that the front panel will come off. Then you must remove the 4 screws from the dispenser door. Finnally, you must remove the the 2 5/16 screws holding down the lid. It will then lift up and the wax motor will be right at the front.

Neptune Washing Machine (MLE200AWW) spins but water is not pumped all the way out. I can hear it slosh in the drum if I spin the drum manually.


Hi, the sloshing sound is normal because of the balance ring which has liquid in it...

I would be concerned about your door latch wax motor ( part # 12002535) though... See Neptune Help for more information about replacing the faulty wax motor with brown colored actuator tip before it damages your machine control board. When the wax motor shorts out it will blow the Q6 triac and then the R11 resistor will burn and your door probably won't lock anymore as indicated by the door locked light not coming on. The next thing you will notice is that your clothes will be soaking wet after the wash cycle because the spin cycle will not work if the door does not lock...

Your machine control board is located above the dryer on the right side.

Every Maytag Neptune front loader with a timer knob (non digital) has a wax motor and all of them shipped with faulty one except the later 2000 series stacker models. You should proactively replace the wax motor with the new design (with black tip) to prevent the Q6 R11 failure on the control board. If you're too late you can try the STAGE 1 repair kit at the same site above.

To inspect your door latch wax motor on the stackers you:

? Unplug machine

? Remove the (2) screws holding center panel and remove panel

? Remove the (1) center screw holding the top panel located inside compartment above washer

? Remove the top panel to expose the door latch assembly

I hope this helps you.

Tip

Maytag Neptune Front Load Washers Machine Control Board Repair


Component failures on Maytag Neptune Font Load Washers such as the pressure switch, wax motor, hot and cold water valve solenoids, timer motor, 24 VDC circuit, and the overall electrical buffer circuit have significant effect on the machine control board. Failed resistors on the machine control board can be used to determine failed washer components. Resistor R9 is associated with the pressure switch, R11 is for the wax motor, R51 for the hot water valve solenoid, R52 for the timer motor, R53 for the cold water valve solenoid, R143 for the 24 VDC circuit, and R162 for the overall electrical buffer circuit. The TRIAC Q6 is also associated with the wax motor while TRIACS Q3, Q9, and Q17 are for the timer motor, cold water valve solenoid, and hot water valve solenoid respectively. These TRIACS must also be replaced should the corresponding resistors fail or burn out especially when there's no power going to the associated component.

The most common problem experienced is the failure of the wax motor as indicated by the inability of the washer to advance to the high speed spin cycle with the "door locked" light not lit. Replace the TRIAC Q6 and the resistor R11 on the machine control board to get the machine back into operation. Use MAC97A6 or NTE5656 for Q6 and a 3.9 kilo-ohms carbon or carbon film resistor for R11. It is recommended to install a 1/2-ampere pico fuse in series with the wax motor to prevent damage to Q6 and R11 should the wax motor shorts out and fails again.

Replacement of the wax motor is a must before installing the repaired or new machine control board to prevent damage to the repaired or new part. Make sure the wiring harness connections of washer components are good and snug fit. Reseat the connectors several times to clean off corrosion build up both on the connectors and terminals.

The door will not lock


There is a small actuator that locks the door before the spin cycle located in the door latch assembly. This actuator is called a wax motor, Maytag part # 12002535 is the redesigned part. It works by heating a ball of wax up which causes the actuator pin to push out and lock the door. It takes around 45 seconds to extend so it is rather slow compared to a typical electromechanical solenoid. The older wax motors have a brown actuator pin while the newer version has a black actuator pin.
The wax motor failure is caused by moisture penetrating the wax motor (older design) over time, which causes the electrical resistance to drop to such a value that the small Q6 triac located on the upper control board overheats and shorts out internally. The triac is essentially an electronic switch that is controlled by a low control voltage, which is provided ultimately by the processor U1. The R11 overheats because the failed Q6 is allowing 120 volts on the triac's center control pin. When this happens, R11 burns and opens up electrically. Sometimes Q6 still looks normal and other times the plastic case ruptures after the failure. However, a burnt R11 is the telltale sign that you have had this failure and the Neptune washer should be left off to prevent further damage to your upper control board.
To inspect your control board you need to do the following:

1. Unplug your Neptune's power cord.

2. Remove three Philips screws along top of washer console.

3. Pull top of control console towards you while pushing bottom of console away from you.

4. Control board is located behind timer assembly on back panel.

5. Inspect the R11 resistor located near the left control board mounting screw.

If your R11 is burnt, you have two options. The first is to repair the control board and the second option is to replace the control board. To repair your control board you will need a 25-watt pencil type soldering iron, solder, diagonal cutters, needle nose pliers, replacement Q6 and R11 components. Whether you repair or replace control board I would not power up machine until the new wax motor is installed or you risk damaging your repaired or new control board again.

If you have not experienced the No-Spin problem consider yourself lucky because you are now aware of the issue and can replace the wax motor before you have a failure. You need to inspect your door lock wax motor and make sure you dont have the older style with the brown actuator pin. Note: If you identify that you have the older brown pin wax motor you need to replace it a.s.a.p. so you don't experience the R11/Q6 failure. I would not use machine until the original wax motor is replaced

Not spinning on spin cycle, also not draining all water during spin cycle


does the door lock?
if no remove the screws from the top of the consol and locate the control board....towards the center left look for R11 location on the board it is a resister is it burned ? if yes you need to replace your board and your wax motor in your door lock assembly.
let me know what you find

Washer does not drain. Checked r11 resistor


Unfortunately, you cant replace the resistor, you need to replace the board. The cause of the R11 resistor blowing, is the wax motor for the door lock assembly. When the wax motor shorts out, the surge blows the R11 resistor on the board, requiring you to replace the wax motor and an expensive board. Major enginering error by maytag. The board costs around $240 and the wax motor is around $15

Won't spin


hi..
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)

just pull the board u can discover burn thru on r11 (you can see the blackened resistor). orders and new board & wax motor on ebay. open the washer & replace the board & wax motor..
thank u
rate me!!!

Machine keeps tumbling after wash cycle is completed.


Make sure that the replacement R11 is in fact connected to pins 1 & 2 of the Q6 triac. If the copper trace on the backside is open on either leg of the R11 to the Q6 then the wax motor will stay energized and that will cause the tumbling after the wash cycle.

That is correct. Take the screws out of the console up top. look for a burn mark on your circuit board. If it's on R11, replaced your door lock wax motor as well at the board.

re original issue, see if R11 is burned. if so, need to change R11 resistor and associated triac, and probably wax motor so it won't do it again. temporary fix just cut out R11, door won't lock. if your model won't spin that way, depress actuator for microswitch from door wax motor. instructions on web.
