GE Microwave JVM1870BF Keypad button not working

The “Time Cook” button on my microwave doesn’t work anymore, all of the other buttons work and we’re still able to use the microwave by using the “30 second” button.

I was thinking of fixing the problem by replacing the Control Panel Assembly, part# WB07X10626.

I found the part (#120) on the GE parts diagram: https://genet.geappliances.com/IPCNet/Dispatcher?REQUEST=IPCNETGETPDF&file=00000000/00048500/00048520.p01.pdf

Could anyone give me their opinion on whether this would fix my issue?

Is it as simple as I think it is?

  1. Remove the griddle,
  2. unscrew the panel screw, slide it up and out,
  3. unplug it
  4. swap it out with the new control panel

I don’t want to do anything stupid.

I found this part, the Key Panel,
GE WB27X10677 Key Panel, AP3203231 | AppliancePartsPros.com

is this more precisely what I need to replace instead?
