maytag neptune washer MAH4000AWW very loud spin noise

by Manage My Life Last activity date:

Maytag MAH4000AWW front-load Neptune Washer (1999). Have service manual but it has no info re: increasingly very loud "roaring" noise during high-speed extraction spin. Sounds like, but much louder than, approaching old-fashioned subway rushing into station. Noise has become louder and louder over last few months. Machine is well balanced and does not hop around or vibrate excessively. What other repair/maintenace options are there to fix this than replacing outer tub bearing, which manual indicates requires whole outer tub assy and is prohibitively expensive; better investment would be to buy new washer.


Second issue: cold water wash: Starts cold but then switches to warm/hot initial fill. I think this may be related to fill valve thermistor (which is exactly where?). I noted from searches this is issue with a different top-load washer with what sounds like a similar board logic control system in regard to water fill. Please confirm.

The loud noise during the spin cycle is almost certainly caused by a bad spin bearing in the back of the outer tub. I see your concern regarding the price of this part. Since the washer is at the end of its average useful life (about 10 years), I recommend that you consider replacing the washer instead of repairing it. There are new models of front load washers by Kenmore, LG and Samsung that have a direct drive motor. The rotor is attached directly to the shaft of the spin basket. This puts less stress on that rear bearing than the belt drive models. I recommend that you consider a direct drive front load washer when you replace this belt drive model. Here is a link for one example of a Kenmore direct drive front load washer at a good price:

Kenmore White High Efficiency 4.0 cu. ft. Capacity Front Load Washer Model 49032

.

The information about the thermistor on the water valve assembly is shown in the image below. The physical location of the thermistor is shown on the parts drawing at the bottom of the image. It is circled in red.

There is not a specific resistance provided for the thermistor in the service manual or technical information for this washer. The test for the thermistor is described below. It should show a difference in resistance at the different temperatures. There is a chance that the washer can add warm/hot water if the temperature of the cold water is too low even in the cold setting. I don't have the specifications for water temperature in this washer. If the temperature of the fill water in the cold setting is obviously hot, then you could have a failed thermistor or a bad control board. You could try to fix this problem by replacing the fill valve assembly but this part costs about $100.

If you need more help, submit additional details and we will assist you further.
