Range: Why isn't my range working?

Replace the power cord if it's damaged or fails due to an internal break in the wiring. Also replace it ifyou move a range to a location with a different electrical outlet type-4 prong instead of 3 prong 220 volt outlet, for example.

The electronic oven control (EOC) board governs the timing and execution of oven functions such as baking and broiling. It's usually in the control console and often has a digital clock on the front of its housing. Replace the electronic control board if it doesn't light up when it's supplied with electrical power, if it doesn't operate properly or doesn't properly send voltage to the bake or broil element (in an electric oven) or burner (in a gas oven).

Some ranges have a relay control board that's separate from electronic control board. The relay board has electrical relays that control voltage going to major loads such as the bake element or a surface element, based on signals from the control board. Replace the relay control board if it fails to properly control voltage to a component.

Many range ovens have a bi-metal thermal fuse-also called a thermal limit switch-that protects the oven from overheating. The oven thermal fuse trips when the temperature in the oven gets too hot. After the thermal fuse trips, the oven won't heat. If the thermal fuse trips after the self-cleaning cycle, try resetting the fuse by turning off electricity to the range, removing the exterior back panel, and pushing the reset button. If the fuse tripped during normal operation, replace it. If the problem persists, the electronic oven control board might require replacement. Reset the thermal fuse after replacing the control board.

This terminal block is located on the back of the range. it's the connection point for incoming power to the range from the power cord. It has heavy connection terminals that can handle the high incoming current load needed to operate the oven and stove top elements. A short circuit in the wiring could damage the terminal block and it should be replaced.
