1. The lighbulbs have never been changed. one is out, and they both seem to have what appears to be glue at the base of each bulb. How does one remove these for changing?
2. I am trying to totally remove the bottom for cleaning. The screws are out, but the bottom is still on. How can I do this?
3. Finally, I would like to know if Goo B Gone can be used on parts to clean them,. It does say to use in a well ventilated area and not to use near heat or flames. What is your advice? Grease Removal?

"How to change bulb?"
Please unplug your oven before you remove or install bulbs!
The
bulbs are often tacked in place with contact cement or hot glue,and
sometimes there may have been enough moisture to corrode and seize up.
You could heat them up with a hair dryer to loosen the glue.
That usually works.
You can find helpful exploded view diagrams (and order parts if needed) by entering your full model number here.
