Charles L Omaha , NE June 02, 2015 Appliance: Model FAFW3574KBO E 90 error code on frigidaire affinity washer We ordered a new control board for the washer after seeing other success stories to resolve this error. I have never done any work on a large appliance, but figured I'd give it a shot. All I needed was a screw driver and about 20 minutes and this was fixed. Works just as expected. I ordered this part on Friday...it was at my doorstep the very next morning. Unbelievably fast turnaround which was a nice bonus. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
