If the dial was bumped, it could have made it too warm for the refrigerator to turn on. It's important to check both the refrigerator and the freezer temperature settings, because the refrigerator gets its cold from the freezer. WebThe compressor compresses the ammonia gas. The compressed gas heats up as it is pressurized (orange). The coils on the back of the refrigerator let the hot ammonia gas dissipate its heat. The ammonia gas condenses into ammonia liquid (dark blue) at high pressure. The high-pressure ammonia liquid flows through the expansion valve.You can …
