Amana AMVC960803BN Error Code Eb0: Blower Motor Not Running
What Does Code Eb0 Mean?
Error code Eb0 on the Amana AMVC960803BN indicates that the integrated control module commanded the ECM circulator blower motor to run, but the motor did not start. The furnace cannot complete a heating cycle without the blower, so it shuts down.
The most common cause is a loose or disconnected power lead at the blower motor. The ECM motor in this furnace receives both its power and communication through a multi-pin connector. If any pin in the power connector is not fully seated, or if the power leads have pulled free from the motor terminals, the motor will not receive power and cannot run. On 3/4 HP and 1 HP models, an open circuit in the inductor (a component in the motor power circuit) will also prevent the motor from starting.
A failed blower motor is another possible cause. The ECM motor module can fail internally while the mechanical blower wheel remains intact. A technician will check the motor connector, verify proper voltage at the motor power terminals, and test the motor module. If the motor is confirmed failed, the motor or its power module must be replaced.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- Eb0 is present — a technician must check wiring connections at the blower motor and test voltage before the motor can be diagnosed
- The blower motor tests as failed — ECM motor or module replacement must be performed by a qualified technician
- The furnace has a 3/4 HP or 1 HP motor and the inductor is suspect — inductor testing and replacement requires professional service
