How to Troubleshoot a Whirlpool Oven Circuit Board

Fault Codes

• Often when a component fails in your range or oven, a fault code is shown on the display of the EOC. The codes F0, F1, F5, F7 or F8 indicate a failure within the EOC itself. If that's the case, you need to replace the EOC. If the fault codes F2, F3 or F4 appear, the oven sensor has failed and must be replaced.

Safety Precautions

• Before testing or repairing any component on your oven or range, you must shut off the power supply to the the appliance. Both ranges and wall ovens have their own breaker in your home's service panel, which is where you turn off the circuit. Whirlpool ranges also have a power cord that you can unplug to disconnect the power supply.

Heating Element

• If a fault code doesn't appear but the oven will not heat, the problem is likely with the heating element. To test the heating element, remove the screws securing it to the rear wall of the oven. Pull the wire connectors off the element and remove it from the oven. Follow your multimeter's instruction manual to test the element for continuity. When it is functioning properly, the heating element has between 0 and 50 ohms of resistance.

Oven Sensor

• If the heating element is functioning properly, the next element to test is the oven sensor. The sensor is secured to the top of the rear wall of the oven with two screws. With the screws removed, pull the oven sensor away from the wall and disconnect the wire connector. Insert the multimeter probes into the two terminals on the oven sensor. When functioning properly, the oven sensor has a resistance between 1,000 and 1,100 ohms. If the oven sensor is working properly, you must replace the EOC.
