Step 1 – Identify noise: Gurgling or hissing that occurs mainly when the compressor starts or stops is usually normal for KitchenAid wine coolers.
Step 2 – Check performance: If the unit maintains proper temperature and there are no error codes, no repair is needed.
Step 3 – Monitor: If cooling performance declines or new noises appear (loud banging, metallic scraping), contact a technician for evaluation.
