Product review (5 stars): Perfect match for the old part & easy to install
Despite a couple of reviews that I read prior to purchasing this item that it is really the broiler ignitor and not the oven ignitor, I did not have any problem replacing this oven ignitor and did not have to make any adjustments.  I am not a skilled handyman, and have fixed a few appliances around the house over the years (furnace, water heater, dryer), so I was willing to try to tackle this one as well.  After watching one YouTube video I had the old ignitor out & the new one installed in about 10 minutes.  It is a very, very easy job to do on your own.  We suspected our ignitor was bad when it was taking an hour for the oven to pre-heat.  So, if you're having issues with your oven pre-heating, or if you can hear the gas going on and off, it may very well be the ignitor.
