Bryan S Austin , TX April 12, 2015 F7 error code Disconnected ribbon cable to keypad to make sure that was the problem - it was. Ordered the part and had it delivered in 2 quick days. Easy repair, just required removing several nuts holding on the panel and then disconnecting the ribbon cable. Probably less than 30 minutes for the whole replacement. 8 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
