Freezer in Kitchenaid side by side fridge stopped making ice,, but will dispense water. Freezer has been emptied and cleaned. When open, I can hear and feel a fan blowing cool air. Have reset circuit breaker and vacuumed lower front coils. Temperature settings for both sections are at max. Still not cold, and don't seem to hear compressor running, only the soft sound of a fan running. Yesterday fridge part was cool, but now this section is also not cold. What is likely the problem?
