A number of common problems are fairly easy to repair without expertise. Electrical problems, for example, can often be fixed by resetting a circuit breaker or replacing a fuse.
The first step to repairing an appliance is determining the nature of the problem. If none of the burners on the range work and the LED lights don't come on, the problem likely lies with the electrical connection. On electrical ranges, if a single burner doesn't turn on, replacement only requires unplugging the old burner and installing a new one or replacing a nearby fuse. On gas ranges, relighting the standing pilot lights is simple and can often get the unit up and running again.
