I have a Sharp R-308J microwave. The door will not latch shut. My guess is that there is a spring that provides tension for the two latches that is not working for some reason meaning that the door won't latch and the microwave won't work. It seems like the door is sealed. Is this repairable?

Usually this can be done easily by removing the door unit and removing the panel to the door wherein you will be able to get access to the door lock. If there is no damage to the pivot or the post to hold the lock and spring , you can push the spring and reset.
If the door will not stay closed it is the spring inside door, or the small plastic piece that holds the spring which is attached to the $80.00 piece called outer door.
To fix it, it is EASY and you do not have to even take the inside cover all the way off. Just remove the three sides of cover by gently slipping a plastic putty knife around rim to release the clips. Then attach the spring to the small hole below where the plastic piece used to be, which is located in the metal on the glass frame piece, use tweezers, hold the other end of spring as you place spring onto plastic door latch and set into place!
Snap the inside cover back on and YAY! FINI!
with butter knife or small flat head screw driver, carefully remove the plastic ring from ther inner door .cheap repair is to hook the spring to the metal fins inside the door if not order outer door panel

and then you'll see how it goes together.
Or you can watch a YouTube video (not a video I made) here that
demonstrates how it's done.
DOOR OPENING BUTTON LEVER
What usually breaks is
the door open lever, but it may also be that the rear side of the door
open button has worn down too far to work.

diagnose and repair this. On an over-the-range model, only the control
panel needs to be removed.
Please unplug the oven

against the door open lever, which would then lift up against the door
