That would be a bad primary interlock (bottom door switch) or its mount.

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 often under the bottom edge of the switch.

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:.

If you only need a switch, you can order part # QSW-MA085WRE0 from Tritronics.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

Cook works microwave timer stuck


If by "manual timer" you are referring to a knob that you turn to set the cook time, then you may have a failure of the motor that turns the timing mechanism, or a lack of power to it.

Our Viking VMOS200 just stopped working. The lights and the countdown timer work, but no fan noise and no turntable spin.


it has nothing to do with the magnetron. first you have to fix step one. then you will know if the magnetron is bad. its one or two of the primary switches on the bottom of the switch tower. usually with these mw if you dont press cancel to stop the mw, and you just push the latch to stop it, those wires heat up and cause the microswitches to burn and loose proper contacts.

put a cup of water in the mw. set it to one minute and as its counting down. push on the latch LIGHTLY, as to not fully open the door and you will hear the magnetron kick on and the turn table start to rotate

Viking model VMOS200 after i put in cooking time and hit start, count down bignes and lights comes on but no running sound and no heat inside.


The Viking VMOS200 is a rebranded Sharp R-530ES. The R-530ES service manual is online here.

You almost certainly have a failed bottom door switch, or that switch's mount is damaged.

See the service manual and this file:

Re. Viking DMOS200 1100 watts microwave oven does not turn on


I'm guessing that's a VMOS200?

If so, that's a rebranded Sharp R-530ES (as is the Dacor DMO2420S) and its secondary interlock (bottom door switch) or that switch's mount is bad.

See this file on door switches. If you only need a switch, you can order a universal type here for $5 postpaid.

The Sharp R-530E service manual will aid you in disassembly and it is here.

Food won't heat up


Hello, I had the same problem, and just fixed mine. Start by turning on your microwave (on mine, the light turned on and timer worked, but the fan nor the plate turned)... push the door upward and see if the microwave turns on... (mine did). so far so good. open the door and take the upper hinge cap off with flat head screwdrive. take the door off and place a small washer on the bottom hinge, put the door back on. your microwave should be good now. essentially, the door just needs to be pushed up a bit so it will work.
good luck, hope that works for you...

Microwave will not heat any thing.


the plate has nothing to do with the microwave heating up the food
but the magnetron that heat the food is bad and will need replacing
I would ask a electronic shop how much they would charge to replace it , and if is not worth it to you then a new one would be a good call
