I replace the spark module on my Jenn Air dual-flame oven and it's very easy to remove and install it by removing the back panel sheet metal cover and it's right there on the spot. Make sure to take a picture on your phone before unplugging the connected wires or if you don't have a camera phone just simply unplug one wire from the broken part and copy install to the designated terminal. By doing this it'll save you a lot of $$$. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
