Squeaking noise heard from within microwave oven cavity.
When the unit is first installed you must remove the tape over the shaft at the bottom or it
will produce a squeaking sound. If placing a lot of food on the glass tray, it will not move
smoothly due to overabundant weight and risk producing squeaking noise.
To ensure proper operation and cooking performance, do not place too much food in the
microwave oven at one given time.
