Shut off the Whirlpool and wait for the oven to cool completely. Cut off power to the appliance at the circuit breaker, since you may not be able to access the power cord on a built-in wall oven.
Open the Whirlpool door to remove the upper wire rack, which slides out and lifts at an angle.
Loose the screws holding the metal plate around the broiler element where it inserts into the Whirlpool cabinet. Push the element firmly into the sockets and tighten the screws.
Turn on the circuit breaker and set the Whirlpool to broil. If the element still does not heat, shut off the circuit breaker and continue with the repair.
Remove the screws in the metal plate and pull the broiling element out of the sockets.
Clip the two probes on the multimeter onto the two terminals on the broiling element. Set the meter to X1, which is the common setting to test for circuit continuity. If the meter displays an infinite or zero reading, the wiring inside the element is broken or burned out and the entire part must be replaced.
Plug in the new broiling element to the sockets and secure with the screws through the metal plate.
Replace the wire rack and close the Whirlpool door.
Turn on the breaker switch to restore electricity to the Whirlpool.
