Amana AMVC960803BN Error Code EE4: Flame Detected When No Flame Should Be Present

What Does Code EE4 Mean?

Whenever the Amana AMVC960803BN is idle, its flame sensor should read no current at all, because there is no flame in the burner box. EE4 is set when the Integrated Control Module sees a flame signal at a time it has not commanded ignition. To keep the situation safe the module leaves both the induced draft blower and the circulator blower running and refuses to start a normal heating cycle, and it holds EE4 on the dual 7-segment display.

The Amana service data lists three causes. The most common is a short to ground in the flame-sense circuit: when the sensor wire touches chassis ground it produces a small microamp current that imitates the signal of a real flame, so the board is fooled into thinking one is present. A slow-closing gas valve that keeps passing a trickle of gas after being told to shut can leave a genuine lingering flame that the sensor correctly reports. Incomplete shutoff of combustion at the end of a cycle can do the same.

EE4 is essentially the inverse of an ignition failure such as EE0, where the module wants a flame and cannot prove one; here it proves a flame it never asked for. It is closely related to EEC (gas valve energized when it should not be) because both point at a gas valve that is not fully closing or a control circuit that cannot trust its own flame reading. Because the shared thread is uncontrolled gas and flame, this is never a homeowner repair — do not reset or operate the furnace.

What You'll Notice

• The dual 7-segment display reads EE4 while the furnace refuses to start a heating cycle
• Both the inducer and the indoor blower keep running continuously even with no call for heat
• There may be a faint gas smell or a small flame visible at the burners when the furnace should be off
• The thermostat asks for heat but the burners never go through a normal ignition sequence
• The furnace will not clear the code with a normal thermostat reset

Common Causes

How This Is Diagnosed

A technician first confirms whether a real flame is actually present or whether the board is only seeing a false signal. With the gas safely controlled they inspect the flame-sense wire and connector for a short to ground, checking where the harness could be chafing against the cabinet or a grounded bracket, and measure the circuit for leakage current with no call for heat.

If no electrical short is found, attention moves to the gas valve: the technician verifies it closes fully and promptly when de-energized and watches for any lingering burner flame after shutoff, which points to a slow-closing valve. Because a valve that will not close cleanly overlaps with the EEC gas-valve fault, that circuit is checked as well before the furnace is returned to service.

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:

• EE4 is on the display — leave the furnace off and the gas supply shut until a technician has inspected it
• A small flame or gas smell is present at the burners when there is no call for heat
• The flame-sense wire is suspected of shorting to ground and the harness needs repair
• The gas valve does not close fully and continues to pass gas after shutoff
• The code appears alongside EEC or persists after the furnace is power-cycled
