What should I do if my refrigerator has an unusual odor?

Set the Hygiene Fresh filter to the POWER setting to address unusual odors. If the odor does not go away within 24 hours, the filter may need to be replaced — refer to the Replacing the Hygiene Fresh filter section for instructions. Also ensure the refrigerator is not located near a fire source such as a fireplace, chimney, heater, or candle, which can cause dust or soot buildup. (Page 36)
