LG Gas Stove Display Not Working: Failed Main Control Board

Описание: If your LG gas stove display goes blank and the oven won’t heat correctly, the issue is often the main control board. In this reel, I show how to test for incoming power:
Locate the main board at the back.
Measure for 120V AC input.
Check for DC output to the display.
If there’s no DC output but power is present, the board is faulty and should be replaced.
This quick check can save time and money when diagnosing oven problems.
