The nF message explained
An nF reading means the dryer has detected a fault in the Wi-Fi module fitted to it.
Next step
Nothing is left for the owner to reset: LG files it as a service item, and the one action it lists is to request repair, quoting nF.
Look-alike messages
nE concerns the link joining the control panel to that same module.
nP has nothing to do with Wi-Fi: it reports missing current at the heater.

Bay Area owners who want LG dryer repair can reach us on (415) 223-7887. Keep the dryer’s model number beside you and read out nF.
Model compatibility: LG reuses codes across series and model years, so nF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
nF indicates a Wi-Fi module fault on the dryer; service is required.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
