Tips From Training: Sliding Door Control Unit Damage – Roger Ross, Training Center Coordinator in Alpharetta, GA, passed along this important tip you need to remember when doing steps 42 thru 50 in S/B 99-072, Sliding Door Alarm Beeps.
He says to make sure you disconnect the negative battery cable before you clean the sliding door ground bolt holes, as directed in the NOTICE. If you don’t, you can have a potential voltage surge and damage the sliding door control units.
