replace the fuse. You have to remove the top grill and then you will find it above the display

A microwave can be dead for many reasons.
If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.
You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and
put it back in, then test it again.
If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

The membrane keypad has failed.
The keypad itself is not available as a separate part, so the control panel frame with keypad would have to be replaced.
This is actually a pretty simple DIY job.
You can part number
WB56X10826
from the Pros
here for
$114.62
plus shipping (that compares to
$166.50
from GE!).
You can also find helpful exploded view diagrams at that link.
At
our Web site, we have a video available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
Then disconnect your keypad strip as shown in the photo below, then remove the screws that hold your circuit board in the old
frame.
Then carefully (since the display is made of glass) move your circuit board to the new frame, and reassembly is the reverse of
disassembly.

SOURCE: Control panel on GE Profile Spacemaker microwave not working
You are right the control panel is very expensive, you can try the filter to see if you can get it working, but I must admit a new microwave oven sounds appealing.
On the JVM2070- and PVM2070-series microwaves, GE does not make service information or separate parts available.
So when you have an error with the controller that does not involve the smart board (and this error does not) then you have to order the control panel subassembly, which on your model (PVM2070SM1SS) is part number WB07X11143 and you can get it from the Pros here for $477.83 (subject to change).
It's very expensive but it's actually simple to replace that part yourself.
You would remove the control panel assembly as shown in
our video here, then remove your smart board and attach it to the new control panel subassembly.
Some connectors on the relays have a lock:
If it's under warranty or
GE Customer Service would give you a break on the the part cost, that would be a big plus for you.
