Surge hit microwave, dead.

GE OTR MW,
Came home to find my microwave completely dead, no lights nothing. The stove clock was blinking so I thought there must'a been a power failure, likely surge on power back on, that fried the mw. What are components get hit in case of a surge?

An over the counter microwave/exhaust combo should be on its own breaker.
It should also be plugged in inside the cabinet above it.
Check for a receptacle and check it first.

All Breakers are good, un/re-plugged it, no joy. Plugged a light, receptacle is good.
What's next?
P/S
Secondly, to satisfy my running mind, let's assume it was a surge, what gets fried?

Usually the more sensitive components get fried first. That would be the circuit boards. Some appliances have built-in surge protection (MOVs) that can sometimes be replaced - but I'm not sure if most GE microwaves have them or not.

Others will be able to give you better answers whether that's a component that's worth replacing or not.

Post the model number.

There is a 15A fuse in most microwave ovens. If it blows the unit will be dead.
However... power surge doesn't usually blow it.

Assuming everything is logic controlled there is a logic power supply.

I won't be able to get the model id until Monday-ish but found a pic in my phone, tho' I know it might not be enough. May be someone might be familiar with the range model of this unit?
