I chatted with the agent. She taught me and waited for me to find the model number of the stove; then, found the right parts for my order. The repair was easy after watching and following the video. I replaced the touch pad first. The stove worked fine. Noted, mineral spirit really helps to clean the old glue on the bracket membrane plate behind the touch pad. Now, I wonder should I return the PCB Main Circuit board or just keep it. And, the lesson is - never use the self cleaning on the Samsung stove if you have it. And, It is better off, don't buy them.
