Amana AMVC960803BN Error Code EEA: Reversed Line Polarity
What Does Code EEA Mean?
Error code EEA on the Amana AMVC960803BN indicates that the integrated control module has detected reversed line polarity on the 115VAC power supply. The furnace will not operate because correct polarity is required for the control module to function safely and for the flame sense circuit to work properly.
The flame sense system in this furnace relies on the flame rectification principle — it measures the tiny DC microamp current that a flame allows to flow between the flame sensor rod and the grounded burner. This measurement only works correctly when line and neutral are wired to their correct terminals. Reversed polarity disrupts this circuit and can cause nuisance flame sensing problems in addition to the EEA fault.
The most common cause is incorrect wiring at the furnace disconnect switch, the circuit breaker panel, or an outlet, where the hot (black) and neutral (white) wires were swapped. Poor or missing unit ground can also trigger polarity-related faults. An electrician must verify wiring polarity with a voltmeter at the furnace power connection and trace the error to its source.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- EEA is present — an electrician or HVAC technician must verify and correct the 115VAC wiring polarity at the furnace disconnect and circuit breaker
- The unit ground connection is poor or absent — a proper equipment ground must be established before the furnace is returned to service
