In the next five minutes
Safe first steps, before the call. Nothing here needs a tool.
Stop the microwave and switch off its breaker, or unplug it if the plug is dry and easy to reach.
Take a photo of the microwave and any code on the display, without opening anything.
Don’t use it again until it’s checked, and keep people away from it.
Everything else about this problem
Is it an emergency?
Is a Viking microwave that isn't working an emergency?
Usually not, but it can be. Because this can be an emergency, leave it off and get it checked; don't reset it or turn it back on. Stop and call a pro if it smells like burning or trips the breaker again.
Symptoms & causes
When a Viking microwave is not working at all, it typically means there's no power, no display, and no response from any buttons. This usually points to a complete interruption of electrical supply, either from the outlet, the home's circuit breaker, or an internal safety component like a thermal fuse. Less commonly, a complete control board failure could also manifest as a total lack of function.
Tools & parts
You will need a multimeter to test for continuity and voltage, which can be purchased. A screwdriver set, including Torx bits for some Viking models, is essential. Replacement thermal fuses or door switches may be needed if identified as faulty.
Safety first
Always unplug the Viking microwave from the wall outlet before performing any inspection or repair to prevent electrical shock. Be extremely cautious of the high-voltage capacitor inside, which can store a lethal charge even after the unit is unplugged; always discharge it safely using a ceramic-resistor tool. Wear insulated gloves and safety glasses to protect against electrical hazards and sharp edges.
When to call a pro
If the magnetron, high-voltage transformer, or main control board is faulty, professional repair is strongly recommended due to the specialized tools and high voltage involved. Tracking down intermittent power issues that stem from complex wiring harnesses or internal shorts often requires advanced electrical troubleshooting skills. Furthermore, any issues requiring disassembly of the microwave's high-voltage components should be left to a certified Viking technician.
Questions people ask
What is the most common reason a Viking microwave has no power at all?
The most common reason is a tripped circuit breaker or a blown thermal fuse, which acts as a safety cutoff. Always check your home's electrical panel first to ensure the breaker hasn't tripped.
How can I check if the outlet is providing power?
Plug another small appliance, like a lamp, into the same outlet to confirm it's live. If the lamp works, the issue is with the microwave itself, not the power source.
What should I do if the microwave smells burnt but has no power?
Immediately unplug the unit and do not attempt to use it again. A burnt smell indicates a serious internal electrical fault, likely requiring professional inspection and repair.
