KitchenAid Oven Error Code F30

F30 indicates that the upper oven temperature sensor circuit has been detected as either open or shorted by the Appliance Manager control board. The sensor should read approximately 1075 ohms at 68°F, and any reading far outside that range triggers this fault. The oven cannot regulate temperature safely until the issue is resolved. The fault can be caused by a bad sensor, damaged wiring, or a problem at the control board connector.

It is not advisable to use the oven while F30 is active. The control board cannot reliably monitor oven temperature without a functioning sensor, which means the oven may overheat or fail to reach the correct temperature. Using the oven in this condition is a potential fire and food safety hazard.

A power reset by disconnecting the oven from power for a few minutes may temporarily clear the F30 code, but the error will return if the underlying fault still exists. Resetting is useful to confirm whether the fault is intermittent, but it does not fix a failed sensor, damaged wiring, or defective board. A proper resistance check of the sensor and wiring inspection is needed to resolve the issue permanently.

A knowledgeable DIYer can diagnose F30 by using a multimeter to check the sensor resistance and visually inspecting the wiring harness and connector at Appliance Manager pins P3-1 to P3-2. Replacing the temperature sensor is a relatively straightforward repair. However, if the fault traces back to the control board, professional repair is recommended to avoid further damage.

If the temperature sensor is the cause, parts typically range from $20 to $80 depending on the specific model. A professional repair call, including parts and labor, generally runs between $100 and $250. If the Appliance Manager control board requires replacement, costs can increase significantly, often ranging from $200 to $400 or more.
