Amana AMVM970803BN Error Code EEC: Internal Gas Valve Error
What Does Code EEC Mean?
Code EEC is an internal gas valve error. The fault is inside the gas-valve control circuitry of the integrated control board itself, so it cannot be resolved by adjusting wiring or external components. The manufacturer's remedy is to replace the integrated control board.
On this modulating furnace the control board drives the gas valve directly, so an internal fault in that circuitry means the board can no longer control gas delivery safely and the furnace stops.
EEC differs from EEb, which is an external gas valve error in the wiring and circuit to the valve, and from ECF, a communication error with the modulating gas valve's stepper motor. EEC points squarely at the board's internal circuitry, which is why board replacement is the specified fix.
What You'll Notice
- The furnace will not operate and the display shows EEC
- The fault persists regardless of wiring checks
- No burner operation on a call for heat
- The code returns after power cycling
Common Causes
| Cause | Likelihood | DIY? |
|---|---|---|
| Internal fault in the gas valve control circuitry | Most common | ✗ Call a pro → |
| Failed integrated control board | Most common | ✗ Call a pro → |
How This Is Diagnosed
Because EEC indicates an internal fault in the board's gas-valve control circuitry, a technician confirms the code is genuine and not caused by an external wiring problem that would instead show as EEb or ECF, then replaces the integrated control board per the manufacturer's guidance.
This is a control-board replacement, which is a professional repair and not homeowner-serviceable.
When to Call a Professional
This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:
- The display shows EEC and the furnace will not run
- The code returns after a power cycle
- Wiring checks do not resolve the fault
Frequently Asked Questions
Can EEC be fixed without replacing the board?
The manufacturer specifies replacing the integrated control board for EEC because the fault is inside the board's gas-valve control circuitry. A technician confirms it and performs the replacement.
Is EEC the same as EEb?
No. EEb is an external gas valve error in the wiring to the valve, while EEC is an internal fault within the control board itself. EEC calls for board replacement.
