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.
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?
One week after the warrantee expired the machine stopped working while grating cheese. Parts are me expensive than a new one but I'd like to educate myself and find out what broke.
The safety switch works. I get no voltage out of the control board red/ black wires. If I apply 14 volts DC to the motor it spins.
Here is a picture of the control board. Does it convert household AC to DC? I see a MOSFET there, so is this a variable frequency drive? Pulse width modulated?

To go into a rental house. I just want to minimize chance of a fridge going out. Unit is a common brand double, bottom freezer type. Is this a good one or what features should I take into consideration?
