Metal oxide varistor

[macallan]

Hi, new to the forum and hope I am posting this in the right place.

I have a bread maker from Japan that a friend managed to plug on 220V....

After opening the device and checking the board I noticed that a metal oxide varistor had exploded and hopefully it might be the only component damaged, in which case I might be able to save the bread maker.

The only problem is that I cannot determine the component specs:(

It should look like this

and from what I could salvage it is about 7mm in diameter. Most component stores require diameter, max voltage, max current etc but I am not really sure what to order. The device operates at 100~110V (with a transformer) and at 1200Watts. Any help most welcome:)

Does it come with a manual? There might be a schematic in there. If not, just do a web search for the schematic. Maybe you'll get lucky and find it.

Check where it's wired, possibly across the supply.  It may not be terribly critical as long as its voltage rating is higher than the expected incoming mains.

It's probably cheaper to get a 220V bread maker than a 1.5kW step-down transformer.  Bread is easy to make by hand *anyway*... ;-)

Does this device play glitched out freak sounds?
