Question about Mr. Coffee 072179228578 12 Cup Coffee Maker
How do you turn the audible ready alert off? It is so loud that I can't brew the coffee when I wake up for fear of waking up the whole house!
I see these posts are quite old but will respond anyhow.
The transducer that is making all the racket is probably a piezoeletric 'speaker' that uses a crystal to which voltage is applied.
These range in size from 1/2" to several inches in diameter but are almost always round (I've seen many and they were).
Look for a cylindrical part in that range of diameter with one (flat) side open.
It will have two wires attached and either one is OK to cut but you might want to use small, heatproof (ceramic) wire nuts to screw on the the clipped wires to avoid causing something else to fail because of the bare wire end.
