Product review (5 stars): SUPER FAST & DISABLE BEEP INSTRUCTIONS
FANTASTIC!  And the beep can be disabled (see below.)  This ice maker is super fast and relatively quiet; the only sound is the compressor that operates at a low-level hum.

TO DISABLE THE BEEPING:
1. Unplug and empty the unit using the rear drain plug.
2. Remove rear cover screws:  top(2), bottom(3), feet(2); tilt cover back, down, and off to the side taking care with the power cord.
3. On right side (left from the rear,) remove the two rearward screws(2) from the electronics box case, and slide the cover back and off.
4. Remove the circuit board screws(4) and pull out the the board.
5. Note the small drum-shaped piezo-electric speaker at the top-rear.
6. At the back of the circuit board behind the piezo speaker, use an X-acto knife to cut through the copper trace leading to the speaker lead; the one NOT leading to the tiny resistor is the better one.
7. (optional) Solder wires to both sides of the cut trace and connect them to a toggle switch on the circuit board case or the rear cover.
8. Reverse the process to reassemble.
