How to use these pages
Pick the symptom closest to what your refrigerator is doing. Each page explains what the symptom usually means, the most likely causes, what you can safely check yourself, and what a technician tests. If several things are happening at once — the fridge is warm and the freezer has ice on the back wall, for example — that combination is often the fastest clue to the real failure.
A symptom rarely identifies a single part. "Not cooling" can be a $200 fan or a sealed-system leak. The pages help you understand the possibilities; a diagnosis confirms which one you have.
