Is there any way to disable the end of cycle buzzer on this machine?
I cannot find any info on the given model number.
Following is a service manual for a couple Maytag stacked ubnits with tugk yours may be the same or close.

You will have to join the site to download the manual but it is a good site with many manuals for the appliance repair DIYer.
You could just disconnect the buzzer or speaker depending on the unit.
Or if you want to get a little fancier wire in an on/off switch.
