What Does Goodman Error Code CONTINUOUS Mean?

The CONTINUOUS error code on your Goodman HVAC system indicates that there's a reversed polarity issue. This means that the positive and negative wires have been swapped, which can cause excessive current flow and heat, potentially damaging components. While this isn't an immediate safety risk like a gas leak, it's crucial to address this issue promptly to prevent further damage and system failure.

Common Causes

  • Reversed polarity at the main electrical panel
  • Swapped wires at the HVAC unit's electrical connection
  • Improperly wired control board or other electrical components

Diagnostic Steps

If... Check Expected
HVAC unit is not running Measure voltage at the control board's power terminals 120V AC (or 240V AC for some models)
Voltage is present Inspect wiring at the main electrical panel and HVAC unit Correct polarity (black wire to L1/L2, white wire to L3/N)
