Greg D Alexandria , VA June 27, 2014 Appliance: Whirlpool 30" Built-In Electric Double Oven Convection-Upper Self-Clean (Gold Line) GBD307PRB00 Whirlpool Oven Gbd307prb00: F2 e6 error code double oven screen blank. How to replace Electronic Control Board. Ordered parts from AppliancePartsPros.com (they were awesome!). Disassembled oven control after watching a few YouTube videos -- job was really rather easy. Attached new control unit one wire bundle at a time (with the old unit still installed to ensure correct connections) then turned power back on to confirm status. All was as advertised -- control unit fired right up and works like a charm. Order from AppliancePartsPros.com -- they will allow returns of electronic parts if you diagnose wrong. Got the new control in a day-and-a-half; the delivery speed was exceptional. Easy job -- do it yourself and save close to $500 by not calling a service tech.
