Door won't latch/microwave won't turn on

Okay. I got the Half Pint Microwave door off, opened it up, found the spring, used a Dremel to make a new point of attachment for the spring since the spring flang on the dooor was indeed broken. The door closes now and microwave turns on - but it doesn't stay on, unless I apply pressure on the top right corner of the door. So the latch is just slightly out of alignment. Will tinker with it some more. Maybe it's just a matter bumping up the lower part of the door a bit. Has anyone encountered this problem?

see this causes and fix it. God bless you
Open Lever If the microwave door won't open the open lever might be broken. This part can be replaced separately.

Door Spring If the microwave door won't open the door spring may have broken. The door spring is located inside the door and keeps downward pressure on the door hook.

Door Latch If the microwave door won't open the door latch might be broken. The door latch is inside the microwave. The door hook, which is part of the door, engages with the latch to keep the door closed during operation. If the door latch or actuator breaks the door may not open.

Door Hook If the microwave door won't open the door hook might not be releasing properly. The door hook is installed inside the door and normally releases when the door is opened. The hook is made of plastic and will break over time. When this happens it will need to be replaced, it can't be repaired.

Button Spring If the microwave door won't open the button spring might be broken internally. The button spring can be replaced.
Button If the microwave door won't open the button might be broken internally. The button can be replaced.

Handle Actuator If the microwave door won't open the handle actuator might be broken. This is a plastic part which can become brittle over time. This part is connected between the door button and the door latch assembly.

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!

The full service manual is here.

If you gently push up on the door latch heads (hook-like devices sticking out of the door) there should be spring tension. If they just flop right up, the spring is off inside.

Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.



Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

You can order parts from Encompass here or the Sears Parts Direct Web site.

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.

On a counter top model, the outer cover will need to be removed to diagnose and repair this. On an over-the-range model, only the control panel needs to be removed.

Please unplug the oven first.

Once it is apart, you'll be able to see how the door open button would press against the door open lever, which would then lift up against the door latch heads (hook-like projections on the door) and the door should open.

You can usually find exploded views and part numbers for Sharp models by entering your model number at the Sears parts site.

I answered this personally via e-mail (and I do not mind peopke writing me personally). I think you may have a broken tab which holds the door latch head spring in place.
