MMV4205AA Microwave will not turn off

I took out something and did not close the door immediately. When I did close the door, the light remained on and the top vent comes on, very similar to when it is cooking. The Stop button does not do anything. I unplugged and replugged; didn't correct issue. I can still enter a time and start oven. Any ideas?

    Am I to understand that everything works fine but the vent fan and cooktop light stay on all the time?

SOURCE: non-working microwave

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Roper Microwave fan won't shut off

THE FAN AND MICROWAVE TUBE RUN OFF THE ELECTRONIC TIMER. OPENING THE DOOR SHOULD SHUT IT ALL DOWN AND WHEN YOU CLOSE THE DOOR AGAIN YOU SHOULD NEED TO PRESS THE START BUTTON AGAIN. IF NOT, ITS SOUNDS LIKE AN ELECTRONIC RELAY IS LOCKED CLOSED ON THE TIMER BOARD.

How do I get my emerson microwave to turn off after the timer is finished?

There are a couple of microwave ovens out there where after it has finished cooking, the light and fan continue to run until you open the door. Then the fans shuts off, but the light remains on. When you close the door, then the light shuts off. If the light and fan go back on when you close the door, then you have a bad door switch.

Power and light turn on, but does not rotate or heat

Occasionally, the larger hard-mounted microwave ovens may become slightly "tweaked" after mounting and will not allow the door switch to activate upon closing, thereby preventing normal operation (sometimes this may occur after many months of normal operation). A symptom of this condition is that the oven light will remain on after the door is closed. It is a simple check to make which can often be corrected by adjusting the mounting screws.

Panasonic nnt774sf door will not remain closed. It appears the top plastic piece on the microwave itself (not on door)that the hooks latch on to is broken. Is there a way to fix this?

You can purchase parts for Panasonic microwaves but home repair is not recommended due to them being lethal if you do something wrong. I would find a good local repair shop and they should be able to find the part and repair. It might not however be cost effective, depends on the part price.
