LG Oven Error Codes - Appliance Fault Codes

The first thing to try is switching the Oven main power supply off for 60 seconds. This usual only works if the fault was set due to a supply voltage fluctuation from a storm or power outage. It may also work if the problem is intermittent. Unfortunately this might only be a short term solution because if the problem is intermittent and the fault returns, the error code will display again.

If that doesn’t work, the problem triggering the error code will need to be repaired in order to clear the fault code.

Why is my LG Oven not working?

Some LG Oven error codes will disable the appliance from operating. The error code will need to be resolved in order for the appliance to function normally again.
