Bosch Refrigerator E5 — Evaporator Fan Motor Fault

Bosch Refrigerator · Error code E5

What E5 Means

The control board lost the speed/tach feedback signal from the evaporator (freezer) fan motor or detected that it is not running at commanded RPM. Cold air cannot circulate properly.

Symptoms

  • E5 on display
  • Freezer cold but fridge warm
  • No airflow heard from vents
  • Compressor running but no cooling delivered

Common Causes

1
Failed evaporator fan motor

Brushless DC motor failed or seized.

2
Fan blade hitting ice

Frost buildup mechanically stalls the blade.

3
Disconnected harness

Power or feedback wire unplugged at the fan.

4
Main control board failure

PCB cannot drive the fan.

How to Fix It

  1. Unplug the unit and remove the rear freezer panel.
  2. Manually spin the fan blade and check for ice contact or stiffness.
  3. If iced, defrost manually and address root cause (clogged drain or failed defrost system).
  4. Check the fan harness connector at the motor and at the main board.
  5. Replace the evaporator fan motor if it is seized or electrically dead.
  6. Replace the control board only if the motor and wiring test good.
