How to fix unit accidentally plugged 220v

It has a burn out power transformer, there's no fuse inside that transformer, carefully dismantle your Keurig , replace that small step down transformer 110v -14.5-0.45amp. that's it.

Sadly the cost and effort to get it fixed wont be worth your time and effort. I burned through 2 units. For the second one i even bought a step down converter and it still popped. Both units went into the bin…shame really, I called so many stores and all worked out too expensive. The reality is that its just not built for that voltage and you would have to modify this heavily and it still wouldnt last.
