Russell S Lebanon , IN July 18, 2015 The range had an f6 e4 error code I went online to trouble shoot and found the repair manual for our make and model range. The manual spelled out what to check. After checking with a voltmeter the problem appeared to be in the control board according to the manual. I ordered the board from Appliance Parts Pros. They were the only ones who would take back any part for any reason including electrical parts. Unfortunately they were out of stock and we had to wait several weeks to get the part. Once I received the part I installed it a couple of days later (today) and the oven seems to be working fine. No more error codes. Thanks Appliance Parts Pros! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
