Again, it may be a defective door switch or shorted cook relay.

SOURCE: Microwave runs with door open

I would say you have a failing door switch or the mount which holds your door switch is loose or broken. In most designs, it is the upper door switch that will produce these very symptoms when it is intermittent or its mount is broken or loose. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. Slamming the door, damage during shipping or transportation and sloppy manufacturing techniques or materials are the primary causes of trouble with the door switch mounts. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

SOURCE: Microwave turntable won't stop running

This is usually caused by either a bad door switch, but may instead be a loose door switch mount or a problem on the control panel.

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

SOURCE: when I open my microwave door, it starts running

.
In most cases, it's not actually cooking, but instead the fan, turtable and light may be on. Yet it does need attention.

What this usually means is that you have a shorted door switch or a bad door switch mount.

It's easy to tell if it's actually cooking, just place a cup of water inside and see if it heats.

If so, that could mean a stuck relay on the control board. If so, we repair these for customers nationwide with our guaranteed $39.95 service. Far less than a new board.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and

SOURCE: The turntable keeps rotating when the dooe is open - Panasonic T994SFR

This is usually caused by either a bad door switch, a loose 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. Other times, 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 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.

We have critical safety & disassembly info (including a how-to video) at our site, linked here.

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

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

The diode that connects to the capacitor needs to be replaced. Once its replaced microwave will begin to heat again.
