check the fuse in microwave How to Fix Microwave Oven Simple Fuse Replacement

Got a short circuit, who knows, some bad connection, probably. or a faulty part? Disassemble it and ressemble carefully, check with tester each step.

enter an amount of time then press start.

check the fuse inside... if you don't hear the click the fuse is likely blown.

mine did the same thing took back apart cleaned put back togerther no fix bout new one

Did you ever find out what was wrong? Ours is doing the exact same thing and we have no idea...

If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Now switch the microwave power on and use a cup of water to test. If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. Replace with same type. If not check the waveguides within the cabin for food particles that can burn and spark, check for rust that can corrode and spark when the ceramic paint has worn out. If there is heating without any issues, you can use the microwave safely

see this causes and fix it. God bless you Door Switch If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently. Main Control Board If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed Touchpad and Control Panel If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board. Touchpad If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad. High Voltage Transformer If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first. Thermoprotector If the microwave runs for a few seconds and stops the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown. Thermostat If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostats.

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

On these, this is usually due to a failing bottom door switch, or its mount. Sometimes the door can also get misaligned due to slamming.See my help file on door switches here.The Viking VMOS200 is essentially just a rebranded Sharp R-530E-series oven. The R-530E service manual is here and it's helpful in working on your unit.All the internal parts will be the same, but outer parts are cosmetically different.You can order Sharp parts from Encompass here or you can call them toll-free at 866-779-5835.

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.
