The electronics on this model are a mess, to put it mildly.

Here is a link to the service manual for your model,

Use it to generate the built in diagnostics to see if they can give you any clues.

Click on your model number to see exploded views of your control panel, and notice that you have more than one electronic component. Don't know which one you replaced, but try the other one. Remember you can return the parts if you do not need them.

Please note: I am no expert. This is what I think. On a Maytag Atlantis this time period is when the electric motor reverses and releases the brake and the tub starts spinning to damp dry the clothes. If the brake did not release, the motor would be stalled creating the odor you describe and hopefully the motor's thermal circuit breaker would open before the motor was ruined. A person could put a mirror under the washer during this time period and see if this was actually the case (motor is stalled...pully not spining). The way I understand they work is the motor is 2 speed forward and 2 speed reverse. This is a way to get the washer transmission to do the requirement with fewer parts. If this is found to be the case, check out the brake. I used 2 C-clamps to get the brake apart as the spring has 200 pound force and the thing would come apart in your face if you just unscrewed the 6 screws holding it together...You can use the C-clamps to release the pressure gradually and with "no excitement". :) Plus you aren't out the 70 dollars for the designed tool for this, that you probably won't use that often. It wold be a great service if a person could rent tools along with buying parts...Hint, Hint, APP!!! :) Hope this observation helped. Rex
