Amana AMVC960803BN Error Code EEC: External Gas Valve Error
What Does Code EEC Mean?
Error code EEC on the Amana AMVC960803BN indicates an external gas valve error: the control module has detected that the gas valve circuit is energized when no ignition sequence is active. This is a serious safety condition and the furnace shuts down to prevent uncontrolled gas flow.
The most likely cause is miswired or shorted gas valve wiring that creates an unintended circuit path keeping the valve energized. A gas valve relay on the control board that is stuck in the closed (energized) position is another cause — in this case, the relay cannot open to de-energize the valve, meaning gas flow cannot be stopped through normal control. A shorted gas valve solenoid coil can also keep the circuit pathway active.
This fault indicates that the gas valve may be receiving power in an uncontrolled manner. Turn off the gas supply valve at the furnace and call an HVAC technician. Do not attempt to reset or operate the furnace until the gas valve circuit and control board relay have been inspected and confirmed safe.

| Cause | Likelihood | DIY? |
|---|---|---|
| Miswired or shorted gas valve circuit | Most common | ✗ Call a pro → |
| Gas valve relay stuck closed on control board | Common | ✗ Call a pro → |
When to Call a Professional
Contact a licensed HVAC technician if:
- EEC is present — turn off the gas supply and call a technician immediately; do not attempt to reset or run the furnace
- The gas valve relay on the control board is stuck closed — the control board must be replaced by a qualified technician
- Shorted gas valve wiring is found — all wiring must be repaired and verified before the furnace is returned to service
