Goodman furnace 3 blink code

The most common code is a three-blink pattern followed by an extended pause. This can mean that the furnace has performed a self-test and found no issues. It can also indicate that the circuit board has failed, which requires professional attention.

The first blink of the furnace indicates that it is running self-tests and has not found any problems. The second blink indicates there may be an issue with the circuit board or it is in standby mode, waiting for instructions from the thermostat to start or stop heating. A third blink, followed by an extended pause, indicates that the furnace has shut off for some reason and needs to reset before it can operate again.

A 3-blink code indicates a failed system board. What can you do about it?

Isolate the problem by removing power from the furnace and checking to see if it stays on. If it continues to blink, there’s an issue with the furnace’s system board. You must check your circuit breakers or fuses for errors if it switches off.
