How do u unlock a ge profile model number JGS905SEK2SS

Find the bake ignitor (you may need to remove bottom drawer or oven cavity floor to get to the ignitor). Turn on the bake. If the bake ignitor comes on (starts glowing after a few seconds) - check the amperage on the bake ignitor wires when it's on. Should be 3 - 3.6A. If less than 3A - replace ignitor. If the ignitor does not come on - check the voltage on the ignitor, should be the line voltage 110-120v AC. If there is a line voltage on the ignitor and it's not coming on - replace.

Part numbers, the first one being the direct replacement: WB13T10045, 12400035, WB13K21, WB2X9998, SGR412, NR020, 5303935066, 814269, 9753108.
Those ignitors are interchangeable, if you can splice the wires, if not comfortable splicing wires - order the first one.

Good luck!
