6. Problems Detected by Smell, Sight, or Sound
All senses must be used to identify LC problems. Get in the habit of taking a few minutes each day to expose all senses (except taste!) to the LC to get a "feel" for how the LC performs normally. This will help to locate problems quickly. For example, often a leak can be detected by smell before it is seen. The majority of problems are identified by sight; most of these are included in the proceeding section.
