LG Range Error Codes: Full List & Meanings

Every LG range error code we have verified against LG's own support pages, with its official meaning. Codes vary by model, so confirm in your owner's manual. Support: LG USA Support (lg.com/us/support).

Codes by system

All LG range error codes

Codes marked "Reset only" or "Service" have no separate page because the manufacturer publishes no owner fix beyond a reset or a service call.

Code	Official meaning	System	Owner action
F-9	The oven didn't reach 150°F after 5 minutes of preheat. Possible causes: an element short, the relay board or its connector. Press Clear/Off, then cut power for 3–5 minutes. If it persists, service is required. Gas models: check the gas shut-off valve is open, but never work on gas parts. Source: LG Canada (lg.com/ca_en). This code also appears in LG's US range error list, so it applies to US models.	Heating	Service
