Amana AMVM970803BN Error Code EEb: External Gas Valve Error
What Does Code EEb Mean?
Error code EEb on the Amana AMVM970803BN indicates the control module has detected an external gas valve error. Specifically, the gas valve is either not energizing when the control module commands it to open, or it is remaining energized when the control module commands it to close. Either condition is a serious safety and operational concern, and the furnace shuts down as a result.
A gas valve that fails to open on command will prevent ignition, while a gas valve that fails to close on command could allow unburned gas to accumulate, creating a fire or explosion hazard. The EEb fault is specifically tied to the external valve wiring and connections — the manual directs checking the polarity, grounding, and wiring in the gas valve circuit, since reversed polarity or a poor ground can cause the valve to behave incorrectly.
A technician must verify the polarity of the 115VAC supply, check the unit ground connection, and inspect all wiring in the gas valve circuit for correct connection and continuity. If the wiring and electrical connections are correct and the valve still does not respond correctly to commands, the gas valve itself may need replacement.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- EEb displays — do not attempt to operate the furnace; call a technician immediately to inspect the gas valve circuit
- A gas valve that energizes when it should not is a safety hazard requiring immediate professional diagnosis
- A technician must check polarity, grounding, and gas valve circuit wiring before determining if the valve requires replacement
