The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

The best place to order Sharp parts is Tritronics. You can also call them at 866-779-5835

Remove to cover, it's under there.

Your model weighs 41 pounds empty.

That - plus maybe adding another 8-10 pounds for safety - us what your installation needs to be able to handle.

I would think the average cabinet could handle that, but it may be better to add a small steel plate or large washer surrounding the mounting screws to help disperse the weight load.

The owner's manual describes the installation kit you can use to mount it in a cabinet or in the wall, etc. That may be helpful.

If you don't still have your manual you can download it here.

It sounds like you may have an intermittent door switch or loose door switch mount.

Does it work differently when you wiggle the door?

At our site, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information.

if the display does light up but it wont turn on,
Broken door switch, broken in the Open position.

But if there is no display at all (no clock, for example) then look at the power supply chain (including the fuse)

Something must have spilled into the mechanism and dried there. You'll need to access and clean it out.
