GE PVM2070SMSS Microwave, Unit runs for a sec then shuts off.

Humming when door is shut. Model #JA229216B 2013. Ge microwave.

Check the unit manual. If you need one, download from here: http://products.geappliances.com/ApplProducts/Dispatcher?REQUEST=SpecPage&Sku=PVM2070SMSS

Sounds like you have a bad smart board, you can try unplugging the unit for five minutes and then back in, if you are lucky this may correct the problem...good luck

It may be a noisy magnetron if the failure occurs in a second or two of hitting "Start" to begin cooking.

See this FixYa solution. even though your model number is different.

Otherwise, if the internal cooling fan is not running when you are cooking, it will shut down after 30-60 seconds or so and stay off until it cools back down.

My PVM2070 Spacemaker Microwave quit working & its DEAD. I checked circuit braker, unplugged unit, checked power is ok, open/shut door, pushed very sensor buttons; its DEAD. Help??

It looks like a component is short-circuited and then it acts to protect. Call a service.

I have the same problem. It was/is a wiring issue behind the key pad. I unplugged the microwave and took the vent and key pad covers off - heed all warnings. Using leather gloves and needle-noze pliers, I removed the wire ties and reposition the wires. I also checked the plastic connectors for looseness. It's currently working, but for how long who knows. Mine is 3+ years old. I will never by another GE product.

I suggest you don't tackle yourself as the capacitor can hold thousands of volts even w/ the unit unplugged. Be careful.

This sounds like the unit is defective and if I were you I would return for replacment!

change your electrical wall plug to a diffferent one, do not use extention wire pls, there is insufficient to drive your microwave, thats why it resets and restarts again
cheers
