Kathleen K Tehachapi , CA March 17, 2014 Appliance: Whirlpool 24" Built-In Electric Double Oven Std-Clean Lower Self-Clean Upper RBD305PRT00 Whirlpool Oven Rbd305prt00: Oven error code E6 F2. How to replace Membrane Switch Touch Pad. Replaced the switch-membrane and also the control board (ordered from a different site). My oven is the biscuit color, which is discontinued. Therefore, I purchased a black switch/membrane, which looks fine, and works well. So glad to have my oven back in working order! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
