Bake Element - Part # 1184162 Mfg Part # 74010750

Bake Element

RepairClinic Item # 1184162

If the oven won't heat, 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 heat, the bake element may have burned out. It is often obvious to see where the bake element has burned out because there will be a hole in the element or blisters on the outside of the element. Test the bake element using an Ohm meter. If it has continuity it's OK. If not, it should be replaced.

Other Causes and Conditions

Incoming Power Problem

Although not as common, if the oven won't heat 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 heat. Check for proper voltage using a volt meter at the socket where the appliance plugs in. For more information on this see the How It Works video above.

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 heat 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 heat, first test the simpler components in the circuit. The oven control board can't be tested easily and will have to be replaced if it is defective.

Other Causes and Conditions

Loose or Burnt Wire Connection

If the oven won't heat, 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.
