John December 17, 2013 for Model Number awh4000aw washer overfilling. found burnt spots on back of control board. (just followed smell) are there other parts that could be bad that caused this and will that burn new $200 control board. Fill switch is ok kicked off fill at 5 gal and secondary at 6 gal. I am worried about timer, it sounds funny. John
1 Answer John, We believe you have a MAH4000AWW "Neptune" washer. The burnt tracers are probably on or in the right hand bottom corner of the backside of the control board. These tracers are the circuit to the fill valve, when they short out they usually keep the fill valve solenoid activated and cause the washer to overfill. You'll also want to check the fill valve solenoids and wiring, (especially the green ground wire)or replace the fill valve WP22002795 and replace the control board. The timers can become noisy after a few years of service, but they seldom fail, as long as it is operating/advancing you'll be OK. Read More...
Joe November 30, 2013 for Model Number MAH4000AWW I am having problems with my Maytag washer model MAH4000AWW. The unit shuts off intermittently during operation. It can be restarted by pushing the start button and will run for a period. The motor seems to work OK; it turns the drum both ways and spins fast. The wax motor has been changed to the new model, and the fwd limit switch was temporarily jumpered out. The incoming water screens were cleaned and the water flow looks good. The hose to the water level switch was disconnected and blown out. The control board has no apparent component damage. The wiring connectors are secure. The discharge pump is clean. The limit switches were tested and appear to be working OK.
1 Answer Hello Joe. Based on the information you provided, it sounds like the control board is bad and will need to be replaced on the unit. Read More...
Craig September 07, 2013 for Model Number maytag mah4000aww I have a washing machine that starts to fill and then stops. Obviously i want to buy the correct part from you so I checked the resistance on the water inlet valve and it appears to be okay. i then looked for burnt connections on the control board-nothing. any other ideas on what to do next? I see that the timer is what you show as next potential culprit. is there a way to test this or other parts with digital multimeter?
1 Answer Craig, The next check should be at the fill hoses and valve. If you haven't yet, check and clean the debris screens in the fill hose and inside the fill valve inlets. Then test the water level switch circuits WP22002921 or 22002994 (depending on serial number) with the air tube disconnected. You would also want to blow in the end of the hose, this will clear any debris or sediment in the tube. If the control board doesn't see a change in the switch circuits on the pressure switch within a specific time, the control "assumes" the washer is flooding and shuts down. Also a resistance test is not as accurate as needed, you can get a proper resistance value, and the solenoid not lift the plunger in the valve body, and this washer is temperature controlled, it fluctuates the valves off and on the maintain a minimum water temperature, if there's a failed solenoid plunger, when the control cycles the power to the other solenoid, if it doesn't lift the washer will stop filling and then shut down after a few minutes. Yes, you can test all the components within this washer with a digital multi meter. Using the wiring diagram and test information on the tech data sheet in the console, you shouldn't have any issues.

Paul September 05, 2013 for Model Number MAH4000AWQ The washer turns on then fills and shuts off like others have described. It will normally run once, then you have to turn it on several times to get it to work. I've changed out the wax motor and the control board and the same thing is happening. Any ideas?
1 Answer Hello Paul. If the board and wax motor are good, you may want to check the wiring and the timer in the unit. Either can cause the issue you are having with the unit. Read More...
Glenn June 29, 2013 for Model Number MAH 4000AWW Our Maytag washer everything works except when it goes to wash and rinse cycle it shuts off. we then have to drain the water. Water fills properly and drains properly. Tub turns freely when empty. I have ordered a new control board AP4026827 (22002989) Control board from your company and am asking if that will solve the problem or is something else needed? Thanks Glenn
1 Answer Glenn, Before you install a new control board, first check and flush the water faucets, The fill hose and fill valve screens. Make sure they are free of any debris or replace them. 12001413, WPY013783, WP96160. Roll the control panel forward, and disconnect the air tube from the water level switch WP22002921 and blow in the end of the tube, this should clear any sediment or debris that may have accumulated in the tube or bell. When the washer is started and the machine fills with water, the control board allows a specific amount of time to pass(12 to 15 minutes) then the board sends out a "check" pulse, if the pulse doesn't return to the control board, the control interprets this as an overfill / flooding situation and turns the fill valve circuit off, and you have to start the cycle over again. If the water level switch doesn't "close" due to a slow fill or a clog in the air tube, the pulse doesn't return to the control board. Read More...
Bob May 24, 2013 for Model Number maytag neptune M#MAH4000AWW My washer comes on when you push the on button. Starts to fill then shuts off. I have tested the door switch it tested good. What now?
1 Answer Bob, You will want to check the control board on the unit, which is located in the control panel near the timer. Make sure that there are no burnt resistors on the control board. If there is then you would want to replace the control board and the lock wax motor. Read More...
Barbara S. January 26, 2013 I love my Maytag Neptune Drying Center, I had to get that out there, but here is the issue, the button that you push to turn the bottom part on, is not working, is there something I can do to fix it?
1 Answer Hello Barbara. Based on the information you provided, it sounds like the control panel is bad and will need to be replaced on the unit. Read More...
David T. January 15, 2013 for Model Number MAH4000AWW Hi, When I turn on my Neptune after a few seconds the machine just stops. The motor won't even rotate. It's stops mid cycle also.
1 Answer Hello David, Open the control panel and look at the machine control board. There is a component just to the left of the center of the board just above a little blue rectangular component that will burn out if the door locking wax motor has failed. If this is the case, you will need to replace the machine control board WP22002989 and the wax motor 12002535 in the control board. Read More...
Sangerx3 January 11, 2013 for Model Number MAH4000AWW Timer will not advance threw the 1,2,3, rinse, spin empty cycle. Washer shuts down unlocks door, I can advance manual from 1 threw 3 and on to spin, need to hit the start bottom each time to complete. Door is locked and I have already install new time 22002867. What now, Thanks
1 Answer Hello Sangerx3, You will want to check your pressure switch and air dome hose to make sure that they are good. The air dome hose needs to be clean and no clogging. Also check the water valve screens to make sure that they are not clogged. If they are clogged they need to be cleaned. Check to make sure that you are getting water to the water valve. Read More...
Chris December 08, 2012 for Model Number mah4000aww Door is not locking and It is not going into the spin cycle. It totally bypasses the spin cycle. I replaced the wax motor but still nothing.
1 Answer Hello Chris, You want to check your wire connection to the wax motor and control board. Also inspect the control board WP22002989 to see if you have any burnt resistors. Read More...
