Furnace

Code	Meaning	Severity
1DL	The control board's internal watchdog timer has tripped, indicating a communication error, internal board fault, or an abnormal operating condition that the main processor could not resolve. moderate	moderate
7P1	The draft inducer (combustion air blower) motor failed to start, stalled, or did not reach operating speed within the allowed time. high	high
9H	The high-stage pressure switch opened during operation, indicating that induced draft pressure is too high, too low, or that the secondary heat exchanger is restricted on condensing models. high	high
E1C	The flame sensor is detecting a flame signal when no call for heat is active and no ignition sequence has been initiated - an unexpected and potentially dangerous condition. moderate	moderate
E2	The rollout limit switch has tripped, indicating that flames have exited the combustion chamber and moved toward areas they should not reach. critical	critical
E3	The draft inducer blower failed to prove operation during the pre-purge sequence, either by not reaching speed or not satisfying the pressure switch within the allowed time. high	high
E5	A general pressure switch circuit fault - the switch circuit is either open when it should be closed, short-circuited, or the switch failed to transition correctly during the startup sequence. high	high
EAF	The flame sensor is reading a microamp signal that falls outside the acceptable range during a heat cycle - either too weak to confirm a stable flame or erratic. moderate	moderate
EE3	The furnace has experienced three consecutive F01-type ignition failures in a row without a successful heat cycle between them, triggering a deeper lockout state. high	high
EE5	The furnace has failed ignition five consecutive times without any successful heat cycle, entering the deepest safety lockout state. A 3-second power reset hold is required to clear. high	high
F01	The furnace attempted ignition three times and failed to detect a flame each time, triggering a safety lockout. high	high
F02	The pressure switch is detecting pressure (closed/triggered) before the inducer motor has started, which indicates a condensate drain backup, kinked hose, or failed switch. moderate	moderate
HUB	Complete reference for all Goodman furnace LED flash codes and alphanumeric fault codes displayed on the control board. low	low
RESET	Step-by-step instructions for performing soft resets, hard resets, and manual switch resets on Goodman furnaces to clear LED fault codes after diagnosing and fixing the root cause. low	low
