Kris L Tallahassee , FL October 23, 2021 Appliance: General Electric General Electric JTP30DP3WW Ge Oven Jtp30dp3ww: Door locked. How to replace Fan Kit. I was cooking at 450 degrees and the oven just shut off and said door locked. We shut off the breaker and nothing changed. Still said door locked. Nothing would work. After researching we ordered the fan kit. It was simple to replace. Be sure to take note there is an adapter that comes with the kit in case the quick connect doesn’t work. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
