Thermador T30IR905SP High-Pitched Noise After a New Installation

For a Thermador T30IR905SP that developed a high-pitched sound after installation, first document when the sound occurs and compare it with the model manual's listed operating sounds. The manual describes droning from a motor or fan, bubbling/buzzing/gurgling from refrigerant flow, clicking from switching, and cracking during automatic defrost; it does not identify every high-pitched sound as normal.
