The popping you hear is either the gear teeth breaking or the chain slipping on the missing teeth. You will need to change out the gear motor. I had to have the main slide motor changed two years ago. You could do it yourself via YouTube. The tech that changed mine said just make sure you mark the chain where the teeth sit to make sure it is set exactly the way it should. He suggested using white-out. I have an extra motor in case it goes out where i can't get a tech. Good luck
Thanks for the info. I’m hearing quite a few of these stories. Spare gearbox might be a good idea for the future.
