Hotpoint UH6F1CW1 Freezer: What a Constant High-Pitched Noise Means

A constant high-pitched sound on a second-hand Hotpoint UH6F1CW1 should not be labelled a failed compressor from sound alone. Hotpoint lists compressor hum, refrigerant circulation, fan movement and some defrost sounds as normal, but a continuous new tone that changes when the door opens deserves a fan, frost, clearance and cooling check.
