Question about Viking VMOS200 Microwave Oven

1 Answer


This past Friday, the microwave would not preheat for convection broil. I tried just heating a cup of water, no luck and heating a muffin, no heat.

Microwave was delivered 12-14-05 and worked fine until now.

The microwave clock works, it turns on but does not heat.

For $1,000, I would think these unit would perform much better than this. In my 50 years of married life, we have never had to call for repairs on a microwave. They just run and run - have I been lucky or does the Viking appliances all work like this? Refrigerator was priced at $6995.00 and the ice maker does not turn off till the ice is about 4-5" above the ice container, so it freezes and does not come out thru the door. Every week, I empty the container and start over.

Also, the SIMMER DOES NOT WORK on my gas stove.

Oh, well I am not a happy camper this weekend

    We too have the same exact problem with our microwave. About a wk ago, it stopped heating food. I called the service co and they said it was probably the magnatron, so to avoid a $175 service fee, we ordered the part and my husband just installed it. Two wires and 4 screws to install and it still doesn't work. If I had it to do over I never would have bought Viking appliances. Everyone I talk to who is looking to renovate their kitchen, I tell them don't even look at Viking. You think you're getting a great appliance, and it's the worst out. My Viking dishwasher never worked from day one. Our refrigerator had the same problem with ice falling all over the floor. Well it turns out it was missing a black plastic shute. And it still isn't working right. And within the last few weeks my range the left side burners click when you try to light the right side burners. We paid over $25,000 for top of the line appliances and all garbage!!!! Thanks for listening! I feel a little better now.

Hi this is tech crazy,he solution to the problem is as follows

Sounds like the magnatron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnatron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnatron, they replace the whole oven.

There is a possiblity that the circuit that provides power to the magnatron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it appart. It is a fairly lengthy process however.
