Jody H Port St. Joe , GA September 26, 2015 Control panel on jenn air downdraft was not working properly I ordered a new keypad and installed it. This is a two person job only because you will need someone to hold the old unit while you disassemble certain parts and hold the new unit as you reinstall them. With two people, it probably would have taken me 45 minutes to an hour to complete the repair. I estimate that I saved between $300 and $350 by doing it myself.
