Product review (5 stars): Easy, inexpensive fix when all igniters failed at once.
All four igniters failed at the same time, so I went with replacing this first instead of the wire harness. My one hint is that after you remove the screws which hold on the top plate which covers the stove itself, just remove the top plate, DON'T move the stove insert too much or it could fall onto the shelf below. Don't ask how I know that. Of course, make sure you turn the gas and electricity off too. Otherwise it's an easy fix, and the price here is half of the appliance store price.
