SOURCE: Over the range microwave
I have the R-1460 in the same series with the identical symptoms. After reading MicrowaveSvc's solution I started taking apart to view the door switches and found the upper door switch to be the problem, but not a switch failure a support failure. A small bottom plastic support post that holds the switch in place was broken (probably from repeated use/abuse) allowing the switch to move when the door hooks were engaged, thus not actuating the button switch. Since the problem was mechanical rather than an electrical bad switch, I made a small support arm for the switch from an old plastic mechanical pencil and glued it in place to hold the switch in its correct position. Problem solved, microwave works! Thanks to MicrowaveSvc's description of door switches.

Hi ,there are two posibility to repair . 1. by ordering parts to the web site of sharp .
2. You may check from shop same type of part bring sample or in the appliances center near you.
SOURCE: broken door catch, possible spring,
If
you gently push up on the door latches (hook-like devices on the door)
there should be spring tension. If they just flop right up, the spring
is off.
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.
We have critical safety & disassembly info at our site, linked here.
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.
The best place to order parts is Tritronics. You can also call them at 866-779-5835.

There are indeed two springs that "cross" each other, and they must be both be replaced to ensure full strength.
