If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383 You may have a bad door switch. We also have a file on door switches at our site.

its a common problem with the sharp microwaves. the control pcb needs to be replaced. it should come with the clock attached to it.

This is a pretty bad design, sometimes you can just remove the upper grill and access the light assy. If the panel is to tight to work in to change the light,you get to take the whole micowave down and remove the outer wrapper to change the light bulb. This is also not a standard bulb (part #WB25X10019). You may be able to get one from Lowes or Home Depot actually Sears would be a better bet, otherwise you will need to order one from an appliance parts outlet. Hope this helps and sorry I didn't design the thing I just fix them.

Check the user book for the unlock code. This could be the child lock mode.

If one of the safety switches are defective, or if there is a sensed power supply fault, the uPC will put the oven in the lock mode for safety reasons.
