What's Happening
The fan that distributes cool air throughout the fridge section has stopped working. The fridge warms up while the freezer may still be cold. Obstructions or a dead motor are the usual causes.
How to Fix It
Check for ice or obstructions around the fan. Test the fan motor by listening for it when the compressor runs — if silent and unobstructed, the motor needs replacement.
Frequently Asked Questions

Why is my Bosch fridge warm but freezer is cold?
When the fridge fan (E21) fails, cold air isn't distributed to the fridge section. The freezer stays cold because it's closer to the evaporator coils.
How much does a Bosch fridge fan motor cost?
The fan motor is typically $30–$60. With labor, expect $100–$200 total. It's one of the more affordable refrigerator repairs.
