If you reply back with your brand and model number we may be able to help you better, but here is our standard reply:

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. 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.

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 find helpful exploded view diagrams and order parts by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

When I open the Panasonic microwave oven door by pushing in the door opening button, the oven starts immediately


There is evidently a fault with the door interlock switches. Don't use it as the oven may avtually be emitting microwaves with the door open.

Get a service tech to quote you for repair as it may be more economical to buy a new one, when you will have a warranty.

Do not try to repair it yourself unless you have detailed knowledge as there are components inside which can deliver a lethal shock even when the oven is not plugged in.

Unit starts when door is open


This is most likely just the blower, and cooling components firing to begin air circulation around the magnatrons, If the mags are firing with the door open you would have burns and radiation poisoning if you were too close. Microwaves produced after the late 80's have many fail safe features to prevent the unit from generating cooking energy with the door open. If you still feel you are having issues with this I will need a model # to better help with the problem.

My JE 1860 microwave starts working when I open the door.


It sounds like the door switch is bad. It may be that the switch is shorted inside. I would think it may really run with the door open, and microwave you.

MIcrowave runs with the door open also


your door switch is mis-adjusted,furthermore the other safety switch on the door should have blown the power fuse in the unit,because by design for safety it produces a short circuit if door opens under operation,so if door was taken off and replaced it was not adjusted properly

Microwave Oven Problem


Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. It's probably not actually heating with the door open, but better safe than sorry! 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 You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383
