Amana AMVM970803BN Error Code Eb0: Circulator Blower Motor Not Running
What Does Code Eb0 Mean?
Error code Eb0 on the Amana AMVM970803BN means the integrated control module has commanded the circulator blower motor to run but detects that it is not running. This prevents the furnace from distributing conditioned air, so the furnace shuts down as a safety measure to prevent overheating.
The circulator blower motor on this modulating furnace is an ECM (electronically commutated motor) that communicates with the control module. The Eb0 fault specifically indicates a failure to run, which can be caused by loose or disconnected wiring at the motor connector, a failed motor winding, or an open or short circuit through the inductor in the motor circuit.
Resolving Eb0 requires a technician to tighten or correct the wiring connection, verify continuity through the inductor, and test the blower motor. If the motor has an open or short circuit, it must be replaced.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- Eb0 displays and the blower motor is not running — wiring, inductor continuity, and motor condition all require professional diagnosis
- If the blower motor tests open or shorted, it must be replaced by a qualified technician
- Loose or damaged wiring at the motor connector requires a technician to correct and retest
