Why is my LG Microwave displaying error codes?

Your LG Microwave will display error codes when the main control panel internal diagnostics system has detected a problem.

How can I reset LG Microwave Error Codes

The first thing to try is switching the Microwave 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.
