If you open the door under the top edge there are screws remove them and the top should lift up.
There is no reset he needs to recheck all the wireing connections.Something is loose or not connected properly.
Then he needs to find out where the power is stopping.You will need a voltage tester.You will want to start at the burner controls make sure they are getting 240 volts then see if it is letting power out if it is then the wuireing is the problem.
Without a voltage tester there is not much we can do we need to find out why that side is not getting power.You can check the top of the control panel for fuses but i do not believe your unit has any.
on the back of the stove there are two wires that are black and red and they look like they have shorted out.......they are burned.
Then that is probably the problem.Clean the wires up and reattach them.
Good i'm glad you got it working.
