110v power supply is not working.

Google the manual for the model of your stove. Diconnect it from the mains or turn the breaker off. If you can remove any screws holding rhe plate in and gently pull it out and make sure the wires are still securely connected on the pins.

If they are pull the stove out and where the main supply goes in there should be some cables from there to the socket in question. With a multimeter set to continuity test each wire from one end and the other. If any don't show continuity then that wire is bad and needs replaced. Also, if you can. Check along the cables going to the socket for a fuse. If there is one test it to see if its blown.

This is what I would do. Without physically seeing the stove the way to get to the wiring might be different. Hopefully this gives you an idea.

Good luck
