Amana AMVM970803BN Error Code EEb: External Gas Valve Error

What Does Code EEb Mean?

Code EEb is an external gas valve error: the gas valve is not energized when the control module commands it, or it is energized when it should not be. Either condition is a safety concern involving the gas system, so the furnace stops.

The causes on this furnace point to the valve's control wiring and supply: reversed polarity, a poor ground, or a wiring fault in the gas valve circuit can all make the valve respond incorrectly to the board's commands.

EEb is one of several gas-valve codes on this modulating platform. EEC is an internal gas valve error within the control board, and ECF is a communication error with the modulating gas valve's stepper motor. EEb specifically concerns the external circuit and wiring to the valve, and all gas-valve codes are strictly professional repairs.

What You'll Notice

• The furnace will not operate and the display shows EEb
• The burners do not light, or behave inconsistently, on a call for heat
• The fault may follow work near the gas valve or its wiring
• No reliable heat delivery

Common Causes

How This Is Diagnosed

A technician checks the gas valve circuit wiring, confirms correct polarity, and verifies a proper ground, since these determine whether the valve energizes correctly on command. The valve's response to the control is tested.

Because this involves the gas valve and its circuit, EEb is a professional diagnosis and repair; it is 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 EEb — treat it as a prompt call for professional service
• The burners fail to light or behave erratically
• The fault appeared after work near the gas valve or wiring
