Goodman Furnace Error Codes: LED Flash Code Guide for GMVC and GMSS Series

Quick Answer

Goodman furnaces display fault codes via an LED on the control board using a flash pattern. Short blinks represent the tens digit and long blinks represent the ones digit.

Goodman furnaces display fault codes via an LED on the control board using a flash pattern. Short blinks represent the tens digit and long blinks represent the ones digit. Common codes include F02 (pressure switch stuck closed), 7P1 (inducer motor fault), F01 (ignition failure), 9H (high pressure switch open), E1C (flame sense without call), E2 (rollout switch open), EE3/EE5 (consecutive ignition lockouts), EAF (abnormal flame sense), E3 (draft inducer fault), E5 (pressure switch error), and 1DL (watchdog lockout). Most codes require identifying the root cause before resetting.

Frequently Asked Questions

How do I read a Goodman furnace LED flash code?

Count the short blinks first (tens digit), then the long blinks (ones digit). For example, 2 short + 5 long = code 25. Alphanumeric codes like F01 or EAF are displayed differently depending on your control board generation - consult the code chart inside your furnace door.

Where is the LED on my Goodman furnace?

The status LED is on the control board, visible through the small sight glass on the lower access panel or by removing the lower door. It is usually red or green.

Can I reset a Goodman furnace code myself?

Yes for most codes - flip the circuit breaker off for 30 seconds. However, E2 (rollout) requires pressing a manual reset button after fixing the root cause, and EE3/EE5 require a 3-second power button hold. Never repeatedly reset without fixing the underlying fault.

What is the most common Goodman furnace error code?

F02 (pressure switch stuck closed) and F01 (ignition failure) are the most frequently reported. F02 is often caused by a clogged condensate drain, which is a quick DIY fix.
