What causes the Green LED (normal) error?
- Not applicable — the green LED is a normal-status indicator, not a fault
How to fix Goodman Green LED (normal) — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- No action needed
If the furnace is heating normally, the green LED simply confirms the board is powered and happy. - If there is no heat
Check the thermostat setting and batteries, the furnace service switch, and the breaker — then look at the red or amber LEDs for an actual fault code.
When to call a technician
- The green LED is on but the furnace will not heat and no red/amber code shows
- The green LED is off entirely — that indicates a power problem
Frequently asked questions
My furnace shows a green light but no heat. Is something wrong?
The green light only means the board has power. Check the thermostat, filter, and breaker; a real fault would show on the red or amber LED.
What if the green LED is off?
That means the board has no power — check the breaker, the furnace service switch, and that the blower door is fully closed.
