Amana AMVM970803BN Error Code EE4: Flame Sensed with No Call for Heat

What Does Code EE4 Mean?

Error code EE4 on the Amana AMVM970803BN indicates the flame sensor is detecting flame presence when the furnace has not called for heat and the gas valve should be closed. As a safety measure, the induced draft blower and circulator blower both run continuously to clear any combustion gases. The furnace will not initiate a new heating cycle until this condition is resolved.

This fault can be caused by a short to ground in the flame sensor rod or its wiring, which causes the control module to read a current signal even without a flame present. It can also be caused by a slow-closing gas valve that allows a residual flame to persist after the gas valve command goes to closed, or by a lingering or lazy burner flame that does not extinguish cleanly when the gas valve closes.

Because this fault involves a possible continuous gas leak through a slow-closing valve or an unexpected flame presence, it is a safety concern that requires immediate professional attention. A technician must correct any short at the flame sensor or in the flame sensor wiring, inspect for a lingering flame condition, and verify the gas valve is closing fully and promptly on command.

Common Causes

When to Call a Professional

Contact a licensed HVAC technician if:

• EE4 displays — do not attempt to reset or operate the furnace; call a technician immediately due to the safety risk of an uncontrolled flame or gas valve issue
• A technician must check for shorts in the flame sensor circuit and verify the gas valve closes fully when de-energized
• A slow-closing or leaking gas valve is a safety hazard that requires immediate professional replacement
