Lower burner failed to light, broiler running fine

Broiler lighting fine but main oven burner not lighting. I deduced the oven igniter was most likely the point of failure. Decided to replace empirically rather than time and money for service call. Process was about as easy as replace a computer part. Removed pan and flameguard. Unplugged part from below (after removing drawer). Such a simple plug I didn't bother to throw the breaker / power down the oven. Pulling it out to get to wall plug not an option. Unscrewed old part, saw a flaw had developed in the element. Screwed on the new part, plugged it in, inserted insulation in the hole. Tested for lighting - lit first time. Replaced guard and pan, oven has worked reliably since. Research time was 5x the repair time, but in all a fraction of time and money to have a "pro."
