- 1). Plug the toaster oven into a grounded, three-prong outlet. If there does not appear to be power to the appliance, check the outlet by plugging in another small appliance that you know works. This will tell you if the problem is in the outlet or the toaster oven.
- 2). If the outlet is not working, check the fuses or breakers in the household fuse or breaker box. Fuses that are black or cloudy are blown. Replace blown fuses. Turn tripped breakers back on.
- 3). Unplug the toaster oven, and plug it back in. If the oven still does not have power, check the power cord for visible damage. If damaged, remove the cord. Connect the leads on the new cord to the leads or terminals on the appliance.
- 4). If the cord appears undamaged, test the heating element. Unplug the appliance. Turn the toaster oven over and remove the retaining screws with a screwdriver. Slide the side panels off the oven. Remove and test each element with a multimeter. If the reading of any element is not between 10 to 18 ohms, replace the element.
- 5). If the toaster oven still does not work, take it in for service.
