Went downstairs, opened dryer door...stuck head inside dryer...nope no lightbulb at all ! This Maytag is about 30+ years old...btw, it's a gas dryer...don't even have the manual for it and it isn't even listed on the Maytag website (Mdl D3303 Series 05).
Have had only 1 replacement item done to it...son replaced the heat sensor thingy inside the control panel...and that was 10+years ago.
