This is usually caused by either a bad upper door switch, a loose upper door switch mount, or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

Sometimes it's a lot to just secure the switch with a drop of hot glue instead of replacing the latch head.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

The best place to order Sharp parts is Tritronics.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

My Sharp R-1460 microwave will not shut off when I close the door

This is odd. Normally it would only run with door closed? Is that what you mean?

There is a door interlock switch that should stop the oven if the door is opened.

THIS IS A DANGEROUS ITEM IF IT OPERATES with the door open.

Our oven started coming on when the door was shut. It is not cooking but the light and the fan come on. Nothing makes it stop except opening the door. I unplugged it for awhile, but that didn't help...

I have the same problem.

I found that by removing the control panel, then moving the small red-buttoned switches around the door open switch seemed to solve the problem.

We felt the problem was a mechanical problem because closing the door very gently permitted normal operation.

Model R-1460, when I shut the door it runs but doesn't heat up. What needs to be done to fix it?

Do you mean that when you close the door, the fan comes on? If so, it sounds like a bad door switch. Probably the secondary interlock switch.
This failure is caused by opening the door when the unit is in cook mode. On ALL microwaves, not just one or two brands.......
Be sure to push the stop button before opening the door to add or stir... Or wait for the cook cycle to end. (This is why microwaves have a two step function on the stop/clear button. Hit stop once to stop cook mode and twice to reset timer).
You should use an ohm meter to check all 3 switches. The switch can be either stuck 'closed' or physically closed but not 'making' electrically.

Sharp Carousel Microwave R-1460A no power, door switch went first

You will want to replace the fuse and door switches. You will not be able to run it without replacing door switches. You do not need a new microwave. Door switches go bad, it has nothing to do with radiation.

Oven makes operating noise when doo is closed without starting

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

Microwave automatically comes "on" when door is closed, but no heat.

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.
