Amana AMVC960803BN Error Code EEb: Internal Gas Valve Error
What Does Code EEb Mean?
Error code EEb on the Amana AMVC960803BN indicates an internal gas valve error: the control module is attempting to energize the gas valve but is detecting that the circuit is open or that the valve is not responding. The furnace will not fire.
The gas valve in this furnace operates on 24VAC and receives its signal from a relay on the integrated control module. If the wiring between the relay output and the gas valve connector is miswired, open, or has a broken wire, the valve will not receive power. An open circuit in the gas valve's solenoid coil — meaning the coil itself has failed — can also produce this condition. A failed gas valve relay on the control board is another possible cause, where the relay cannot close to complete the circuit.
A technician will use a voltmeter to check for 24VAC at the gas valve terminals during a call for heat. If voltage is present but the valve does not open, the valve must be replaced. If voltage is absent, the wiring and the relay on the control board must be tested.
Common Causes
| Cause | Likelihood | DIY? |
|---|---|---|
| Miswired gas valve circuit | Most common | ✗ Call a pro → |
| Open gas valve circuit | Common | ✗ Call a pro → |
| Gas valve relay stuck on control board | Common | ✗ Call a pro → |
When to Call a Professional
Contact a licensed HVAC technician if:
- EEb is present — gas valve circuit diagnosis requires a voltmeter test during an active call for heat, which must be performed by a qualified technician
- The gas valve is confirmed faulty — gas valve replacement must be performed by a licensed professional
- The gas valve relay on the control board has failed — control board replacement requires professional service
