Goodman

EE

Lockout

No 115V to control / internal / door switch

No line voltage reaching the IFC, door switch open, or an internal control condition. This is power, not a ComfortBridge data-pair code.

Walk EE in Diagnose

4 plates — walk the one on the cabinet

First check

1 Measure at the IFC under load

On Goodman GMVC80 line-voltage codes are incoming power. Measure L1/L2 (or L1/N) at the board while it is trying to run, not just at the disconnect. Furnace switch, breaker, and blower-door switch fully made.

Expect: Voltage in the rating-plate window under load.

The rest of the walkthrough is Diagnose.

On the plates

  • L1/N at the IFC, door switch, incoming 120 VAC under load.
  • Transformer 24 VAC secondary. Internal IFC failure only after line power is proven.
  • Do not chase a data pair because an older note called EE ‘bus.’ On this chart EE is power/internal.
  • Furnace switch, breaker, and blower-door switch fully made.
  • 115 VAC at L1/N on the IFC.
  • Do not confuse EE on this board with a comms complaint — check the data pair separately if the stat is dark and the IFC is alive.
  • Switch, breaker, door switch. 115 VAC at L1/N.
  • If the IFC is alive and the stat is dark, that is the data pair — not EE.

Plates that use EE

Same number, other makers

EE on Goodman is not the same code on these plates.
