If the oven won't turn on, check the bake element. The bake element is a black tube near the bottom of the oven about as thick as a pencil. When it is operating normally, the bake element will glow red hot. If the oven won't turn on the bake element may have burned out. It is often obvious to see where the bake element has shorted out because there will be a hole or break in the element. If the bake element has burnt out or shorted it should be replaced.

Other Causes and Conditions

Incoming Power Problem

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.

Oven Control Board - Part # 1009029 Mfg Part # 74007221

Oven Control Board

RepairClinic Item # 1009029

The oven control board has a set of relays that turn on and off power to the bake and broil circuits according to the customer settings and sensor input. If the oven won't turn on the problem is usually with the heating components. However, if the oven control board is bad, it might not send voltage to the heating components. To determine why the oven won't turn on, first test the simpler components in the circuit. If no power is present at the proper terminals on the control board, the control board will need to be replaced.

Other Causes and Conditions

Loose or Burnt Wire Connection

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.
