If your KitchenAid oven broiler is not working, the broil element is the most likely cause on an electric range or oven. A properly heating element should glow red hot; inspect it for holes or blisters, then use a multimeter to check for continuity and replace it if the test fails. On a gas KitchenAid oven, a weak oven igniter can prevent the broiler burner from lighting. If the igniter glows for more than 90 seconds without ignition, it likely needs replacement. A defective oven control board may also fail to send voltage to the broil element or igniter. For gas models, a faulty ignition module or damaged bake or broil spark electrode can interrupt ignition. Check the electrode for cracks or a damaged tip, and verify proper outlet grounding and polarity if the burner lights and then goes out. Less commonly, the temperature control thermostat may be defective and unable to regulate broiler heat. Always disconnect power before testing parts, and enter your KitchenAid model number to find the exact replacement broil element, igniter, control board, or other part for your oven.
01 - KitchenAid Range/Stove/Oven Broil Element
The broiler element may have burned out. When the broil element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the element has burned out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.

The igniter glows to ignite the gas in the burner assembly. To determine if the igniter is defective, observe the igniter as the oven is heating. If the igniter glows for more than 90 seconds without igniting the gas flame, this indicates that the igniter is too weak to ignite the gas. If the igniter is weak, replace it.
An oven's control board will often be used to send voltage to the broil element or the igniter. If the control board is defective, the voltage may not be sent to the component and the oven broiler will not work. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the broil element or igniter after reviewing the appliance's wiring diagram.
For gas ovens using a spark igniter, a faulty ignition module could be responsible for the oven only heating intermittently, resulting in an inaccurate oven temperature. If you do not consistently see a spark near the bake or broiler burner tube when the oven is turned on, use a multimeter to determine if voltage is reaching the ignition module. If power is present, the ignition module is likely defective and will need to be replaced.
05 - KitchenAid Range/Stove/Oven Bake or Broil Spark Electrode
For broil burner ignition an oven broiler burner spark electrode is used to ignite the gas. The electrode is a device that sits right next to the broil burner. It functions like a spark plug. As power is applied to it a spark jumps from the spark electrode tip to the to the electrode shield, igniting the gas. If the electrode is broken or worn out the spark may not occur. Visually inspect the electrode assembly for cracks in the porcelain housing or damage to the electrode tip itself. Be aware that a proper ground and the correct polarity of the incoming voltage to the range is necessary for the electrode control to sense... the presence of a flame once the burner is ignited. If the burner goes off after ignition check for proper ground and the correct polarity at the wall outlet.
06 - KitchenAid Range/Stove/Oven Temperature Control Thermostat
The temperature control thermostat regulates the broiler temperature. If the thermostat is defective, it may fail to heat the broiler element. The oven thermostat is not repairable—if the thermostat is defective, you must replace it.
