LDE3017ST LG Range - Overview

Dropped a hammer on the range while removing a ceiling light. Viewed a How-To video on Google. Ordered the needed parts. Followed the steps from the How-To video. Reinstall was a bit tricky by myself - could have used an extra set of hands. I have a few words of caution:
1) Put something between the range top and range - like a sheet or drop cloth - to prevent a dropped screw from falling into a crevice in the stove. I dropped a screw and was unable to retrieve it, even with a magnet.
2) Makes sure you remove all bumpers, screws, clips, etc. from the item being replaced and put them on the new item if the new item does not come with replacement bumpers, screws, etc.

Replaced the control board, part number EBR64624601. Took the back off the oven, removed the screws the held the board in, put the new board in and replaced the back. The LG range is a double oven with the bottom oven both convection and regular heat element. Problem started after using the self-cleaning feature.

Initial failure of over range microwave Aug 3rd. Control Panel worked but no heat. Took to local LG authoriaed local repair place. They fixed it quickly and we re-installed it. Worked fine for 2 months then had similar failure again. Agaim took to same authorized repairer. They kept unit for 3 months but finally concluded theu could not fix it and suggested we contact LG for a partial refund. When they tested the unit during re-assembly in my presence, there was a blue flash and the fuse blew. Since we had built a custom tile mural back splash around this unit, I brought it home, ordered a number of time delay fuses new capacitor and two new high voltage diodes. However, using my Fluke DMM, I checked the existing capacitor and high voltage diode and they checked OK so I just replaced the time delay fuse. The high voltage transformer leads had 2 possible ways to connect to capacitor and diode. Tried one way, plugged unit in and turned it on, and immediatly blew the fuse. Replaced the fuse and reversed the high voltage transformer connections,amd turned unit pn, and it worked perfectly. Since we had experienced several power failures during the time of the original failure, the repairer concluded that power spikes might be at fault, so I also purchased a TrippLite ISOBAR4ULTRA 3300 Joule surge protector between wall outlet and microwave, and re-installed over range. It has worked perfectly since.
