Error codeF22 code
ApplianceRange
When F22 shows up on an LG range, the machine is flagging a steam sensor failure. That is the entry in LG’s cooktop and range code table.
Quick fix from the manual
Cut power to the unit at its circuit breaker.
Keep it off for 30 seconds.
Switch the breaker back on.
Which units it applies to
Ranges and ovens are the units named. The manual does not narrow F22 to a series or a model line.
When it comes back
Should the failure reappear after the reset, the manual calls it a service matter.
Look-alike messages
If the display is not quite what you read, compare F25 (another steam sensor failure), F2 (upper oven thermistor error) and F27 (cooling fan stalled or locked during self clean).
