If you lift the top of the range you should be able to find the label with name and model number of your particular range. Most were Attwood. The part is a piezo ignitor. Look for the manual for your particular range and you should be able to find numerous sources for the ignitor.
I'm with Vaughn - even when ours worked, I used a bbq lighter - liked that I could start the bbq lighter and leave it on until the stovetop fired up. no guessing and clicking the igniter in a frenzy making sure it didn't fill the rv with propane and go WOOSH
