Amana AMVC960803BN Error Code EEA: Reversed Line Polarity

What Does Code EEA Mean?

The Integrated Control Module on this furnace expects line power wired to a specific polarity, with the hot conductor on the line terminal and neutral on neutral. The board senses polarity electronically because its flame-detection and safety logic reference the neutral leg. When it sees the 115V hot and neutral reversed, it refuses to run and reports EEA, because operating with swapped polarity would undermine those safety references.

Amana lists two things to check for EEA: the polarity of the 115V AC supply to the furnace or module, and the unit ground. Reversed polarity usually traces back to a miswired outlet, junction box, or disconnect, and it commonly shows up right after new wiring, an outlet replacement, or an installation. The service instructions also flag a poor unit ground as a contributor, so grounding is verified alongside polarity. Correcting it means reviewing the wiring diagram and fixing the connections, which is electrical work for a professional.

EEA sits in this model's electrical family and is closely tied to supply integrity. EEA and E10 both concern how the furnace is fed and grounded: EEA is reversed line polarity, while E10 is a grounding fault from a poor neutral connection, and a marginal ground can play into both. Separately, EE5 is an open 3-amp control fuse from a low-voltage short, and EEE is an internal fault the board detects within itself. Because a poor ground can also surface as EE7, the igniter fault or improper grounding code, a technician who finds EEA will typically confirm both polarity and ground before returning the furnace to service.

What You'll Notice

• The furnace will not start and the display shows EEA
• The problem appears right after new wiring, an outlet or disconnect replacement, or a fresh installation
• No normal ignition sequence, inducer, or blower response on a call for heat
• Other outlets or fixtures on the same circuit may show signs of miswiring
• The condition persists through breaker resets because the wiring itself is reversed

Common Causes

How This Is Diagnosed

A technician checks the 115V supply at the furnace to confirm hot and neutral are landed correctly, comparing against the unit wiring diagram, and traces a reversal back to its source at the outlet, disconnect, or junction box. Because Amana pairs polarity with grounding for this code, they also verify the unit ground and neutral integrity, since a poor ground can accompany or contribute to the fault.

Once the reversed conductors are corrected and a proper ground is confirmed, the furnace should clear EEA and start normally. This is voltage and wiring work; identifying and correcting reversed line polarity is a job for an HVAC technician or licensed electrician, not a homeowner repair.

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 EEA and the furnace will not run
• The code appeared after new electrical work, an outlet swap, or a new furnace installation
• You suspect an outlet, disconnect, or junction box near the furnace is miswired
• You are unsure whether the furnace ground and neutral connections are correct
• The fault remains after cycling the breaker
