Question about Maytag Washing Machines

1 Answer

Maytag Neptune MAH5500 smelled like burning plastic at the end of the cycle. (The whole basement smelled bad.) The smell seemed to be coming from the plastic part at the top where it latches.

I opened the back and it looks great back there. the belt appears totally fine. We ran it again 3 times and there is no burning plastic smell, so it happened suddenly once and has not repeated. Does this mean the tub bearings are bad, or could it be something else? The tub seems to spin easily and if I push down on it at the rear of the machine it doesn't seem to move much.

    No signs of burning on the clothes. No signs of burning or damage around the tub rim. Right after this happened I sniffed all around the front tub edge and the burning smell was *definitely* coming out of the piece of plastic at the top where the door latch goes. Also that spot was hot (as shown by infrared camera). Maybe some component inside the washer melted and the fumes vented out through the latch mechanism?

    Is there some electrical part that could fail and the washer would *seem* to work?

    The door latch safety switch will be in that position. Its a switch that turns off the machine and locks the brake when or if the lid or door is opened during spin. On a front loader, the switch will lock as soon as the machine starts washing. You may have to lift the top of the machine to get access to it and look properly.

    If you look further down the page, someone wrote a post up about what problem you have had. It would be worth checking it out. Something about the wax drive motor in the lock and this could fail and cause damage to the power board. Check the door gasket and make sure it hasn't got a hole or tear in it which allowed water to spray on the electrical parts.

    The post lower down says that if the wax lock motor fails, the machine won't run at all, which doesn't match my behavior where it now seems to be working fine. I guess I can try opening it up and looking for burnt or melted parts.

    I opened up the machine and inspected the electronic parts. No sign of anything burnt or melted. Control board looks fine. Everything looks pristine. Machine continues to run normally without any problems or burning smell. And it doesn't seem to be particularly loud during spin. So I don't know what to think.

Tub bearings get worse, if they faulty, the machine would be noisy and getting louder. Sudden burning smells usually mean an electrical failure of a component but if this has stopped and the machine is working properly, its possible that something has got caught up in the rim of the tub or gasket area and during spin it has got "burnt" by being dragged around the edge. Have a close look at your clothes that were washed on that day for signs of burning or damage and around the top at leading edges of the tub for signs of melting or damage.

    Mystery?? I know it sounds crazy, but are you sure it was the washing machine? Its not the first time that ive come across a suspected failure (burning) on an appliance and it was something else nearby. (Hot water system, clothes iron and a toaster once. lol.All I can say, is to keep using it and hopefully it keeps working properly. Cheers.

    Well, we had the fire department out to investigate and they went all over with IR cameras and fingered the washing machine. It was showing up as hot on their camera and the smell was really strong right at the latch area at the top of the door rim. Even after the basement was aired out, the smell persisted around that latch area. So it seemed pretty definite. We reached the same conclusion: keep using it until it happens again.

    OK, I would say that the door lock has shorted internally with no obvious external signs. As I read below, there s something about a wax solenoid that can fail on these machines which has something to do with the door lock. Rather than risk a fire or damage to the machine, It may pay to replace this. perhaps you could confirm over the phone with your local Service Agent who would be conversant with your make and model. All the best.

pump is probably clogged not allowing all water to drain out. Should never see water in the tub at the end of a cycle. About once a month you should run your washer through a cycle with hot water and bleach. Doing that should keep the moldy smell down.

The drum belt could be rubbing on something inside. Does the dryer make a squeeking noise? Se if there are small rubber particles on the bottom, this will indicate a deteriating belt.

A burning smell while Maytag neptune was washing.

Shut down and unplug machine a.s.a.p.! It could be your door latch wax motor failing which will burn the R11 (resistor) and Q6 (triac) on the machine control board. You did not mention which Neptune you had... If it is a MAH3000, MAH4000, MAH5500A or a 2000 stacker and you have not replaced the door latch wax motor (12002535) then your time is up. See for details for the repair kit or you can purchase a new control board and 12002535 wax motor and be up running quickly before the clothes pile get too high.

It could be the seal and/or bearings if the machine is starting to get loud in the high speed spin cycle. If so, See for the seal and bearing kit plus they offer a special Neptune bearing tool for rent called the tony tool. A Maytag technician will want to charge you $900 to replace the whole outer tub? Why replace it when just the bearings and seal kit need changed?

check to see if the door boot is intact. if there is a hole in it water could be getting to the motor control board and you are in danger of shorting the machine out. the other possibility is the main computer board may be on its last legs and is doing a slow sizzle
