Gas Dryer doesn't heat up - but that isn't my issue

I have a gas dryer that doesn’t heat up but otherwise runs fine. Reading all the posts regarding this issueon this excellent site gives me hope to fixing this issue. What I need help with is taking my unit apart. People talk about looking at the igniter glowing and I haven’t a clue how they are doing that. Are you running without the front panel? Are you viewing from behind the unit?

You are welcome. Keep us posted.
