Product review (4 stars): Oven not lighting or slow/uneven heating? This Oven Ignitor is exact fit
I've replaced this ignitor before, about every 2-3 years. (that's why 4 stars) It is cheap enough, however. The 1st one bought locally cost $137 plus labor. It only takes about an hour to remove and replace it though. You will need a screw driver, pair of pliers, maybe an 8mm socket and bright light. Shut off the gas feed first, remove all trays, racks, etc. first and get a nice open area to move around in. Next pull the bottom drip cover forward and lift it out of the oven area. There are 2 screws or nuts under there that hold the flame spreader underneath it (in the broiler area). Take that loose first. Your oven/broiler may have a shield in the broiler around the burner. It is very hard to remove and you don't have to! But you may have to bend it a little in the back to get the screwdriver on the 2 screws holding the ignitor in place. After that it's simple. Unplug the 2 wires from it down to the back/bottom of the broiler. feed one back through the heat shield but first put a piece of string on it to pull the new one back through the channel as it is very hard to do freestyle. Plug the new wires in, hang the new ignitor, reattach the flame spreader, replace the oven drip cover, turn the gas back on and you're ready to cook. There may be other ways to do this but I've not found them and this works repeatedly for me. Thanks for reading.
