I think you'd have to revisit everything starting at the connector, including the wire gauge, the power supply, converter, then the specific circuit for the stove. Leave anything undersized and it won't work and/or will start a fire.
Known your amps and you will likely find you can salvage much of what's there. Be prepared to replace it all.
Also, read and print everything you want from this site, before, oh, say this time tomorrow night when it all goes offline for good.
