The 3 most common part(s) or condition(s) which cause the symptom Oven won't turn on are listed below starting with the most likely. Check or test each item and watch any available videos.
Although not as common, if the oven won't turn on it is possible that the appliance is not receiving proper voltage. Electric ovens require 220 volts of alternating current. If for some reason the appliance is receiving significantly less, the oven won't turn on. Check for proper voltage using a volt meter at the socket where the appliance plugs in.
If the oven won't turn on, there might be a burnt wire supplying power to the bake element. Sometimes the wire supplying power to the element burns out right near the element itself. Check for this by just looking at the wires leading to the element. If they're burned out it is usually easy to spot.

If the oven won't turn on, the oven thermostat might be defective. Although this is not as common as other components, the oven thermostat sometimes fails completely and does not allow current to pass through. After checking other, more common components, consider replacing the oven thermostat.
