Amana AMVM970803BN Error Code EEC: Internal Gas Valve Error
What Does Code EEC Mean?
Error code EEC on the Amana AMVM970803BN indicates an internal gas valve error has been detected within the integrated control module. Unlike EEb, which points to an external wiring or valve issue, EEC identifies a fault inside the control module's own gas valve control circuitry. The furnace cannot operate, and the only remedy specified in the manual is replacement of the integrated control board.
Modern furnace control boards include internal logic and relay circuits that manage gas valve operation. These internal components can fail due to component aging, voltage spikes, or manufacturing defects. When the control module detects that its own internal gas valve circuitry is not functioning correctly — whether a relay has failed, an internal component has shorted, or the gate logic has malfunctioned — it reports EEC and locks out to prevent unsafe gas valve operation.
Because EEC identifies an internal fault inside the control board itself, there is no external wiring or component to inspect. A qualified technician must replace the entire integrated control module. This is not a repair that can be performed on the board itself, and attempting to reset or bypass the fault will not resolve the underlying hardware failure.

When to Call a Professional
Contact a licensed HVAC technician if:
- EEC displays — the integrated control board has an internal gas valve circuit failure and must be replaced; no other troubleshooting steps are specified
- Control board replacement on this modulating furnace must be performed by a qualified HVAC technician
- After board replacement, the shared data must be re-populated using the CoolCloud HVAC App
