Question about LG Ovens
I asked a question of another tech and his abridged answer was not helpful. I have taken the PCB OR electronic control board out and visually inspected it. The two fuses are visually perfect. No burns, no blackened areas on the glass and no burnt parts on the board. Also, the board itself is not burnt. Can the PCB be damaged without any visuall sign? The breaker and the outlet have power.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

If the display is totally out it is likely the thermal fuse this is located where the wire connectors plug into the board it looks like a small resistor in a platic shrinkwrap type sleeve. test it with a continuity meter.

Hi, well this is a brain tester!! I think you need really to look at this in a simple way. Check to see where the door lock wires come from first? Find where the mains power comes into? then if it goes directly to the main control board then check to see if there is any power getting through the board to the otherside where the wires disapear into the cooker. I would consider checking the control board for any signs of burn damage and then look at the clock unit to as these are normally the main components in the cooker that will stop it from working.

Stuck keypad may mean relay is turned on.
Determine if problem is with the Key Panel or Control by:
1. Pushing CLEAR/OFF pad.
2. Disconnecting Ribbon Cable from control and waiting at least 32 seconds to see if Code recurs
If code recurs, problem is in the control. Replace control.
If code does not recur, problem is with the Key Panel.

Ouch...sounds like the control module is blown. Thats the electronic timer. I've known this happen on several occasions. Bad luck!
