It shows how to remove the door and talks about how to release the latches.
It sounds like whomever cleaned it ... may have removed the door and not reinstalled it correctly??
Helpful?

I can't help you much with how but here is a parts diagram that can help.

Door catches.

One of the latches has broken off and is not lifting the other latch clear of the housing. Remove from any power source, remove the cover of the cabinet. Slacken off the clamp mechanism and ease the clamp over the guide to allow the door to open. When a new door lever is in place, the door may be easily adjusted by slackening off the screws that clamp the door catch/actuators in place whilst holding the door closed and then tightening the screws. The rear of the door may be adjusted by slackening the lower door hinge screws and adjusting as required.
I hope that helps.

It sounds like the light switch isn't being deactivated which is preventing the microwave from operating (a failsafe).
Look to see that the buttons inside the microwave (where the latches are inserted when you close the door) are actually being pressed.
They may be out of place, obstructed, or your latches on the door may be damaged.
If you don't see anything wrong, try pressing the buttons yourself (with a pen bottom) to see if the light goes off.

It may be the latch head spring or the door open lever or button.

DOOR SPRING LATCH HEAD HOOK

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.

you have to separate the door panels (as shown in the attached photo) 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.

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.

If not, let me know. We have many Sharp manuals and if we have yours, we can link you to it at no charge.

The best place to order Sharp parts is Encompass (formerly Tritronics).

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Hi, this is a faulty door latch assembly. the switch is malfunctioning. the entire door latch assembly will need to be replaced.

This is because of the broken latch. There are switches inside the oven that are operated by the door latches to make sure you're not trying to use the oven with the door open. With the new door, your oven should be back to normal.
