Actually, I had a gas Maytag dryer in about 1995 that did not have the telltale door. It had a tiny white plug that you could remove to see if the burner and glow thing was working. I think when maytag dryers went into the removable sericeable front panel design, they decided it was not necessary to have the door. I have a Maytag DG906 with the door and the front panel is not removable, the whole cabinet has to come off, so thank God for the burner service door. Funny, the gas washer! Maytag did make those, in wringer styles for farms about 75 years ago.
