It is likely that the convection element is burned out and needs to be replaced. If all other functions are working then this is the place to start. Teh back panel inside of the oven can be removed by removing the 4 visible philips screws on it. The element should look smooth and round, if not then it needs to be replaced. Be sure to turn power off to the oven before replacing it. Remove the screws that fasten the element to the back wall and gently pull the element away from the wall an inch or so. the wires will be exposed and can be unclipped from the element do not let them fall inside of the back of the oven or you will have to remove the oven from the wall to get at the back panel. Install the new element in the reverse procedure. If the element looks good then it will have to be tested with a multimeter to verify that it is still good before proceeding to check the selector switch for burn marks.

if there's only two wires going to it it doesn't matter where they go you have another problem

If the cooling fan is constantly running then means thermal overload probably faulty, it has failed in closed position. Best to get an engineer to help warmest regards Richard the Repairman

now, Turn the oven off at the circuit breaker and wait for more then 5 minutes and then turn breaker back on.this will reset the oven.this is the only way to reset.but if you have tried this same procedure and this did not help, then it might be the problem with door switch or door assembly.

Try unplugging it and letting it sit for a few minutes and then plug it back in. That worked when I Maytag did the exact same thing.

There are adjustment screws or bolts on the hinge attachments to the oven. Loosen them and adjust the door using wedges to hold the door in place.
