Oven Settings

Frigidaire convection ovens can be used for convection cooking and for traditional, non-convection cooking. Therefore, troubleshooting a convection oven fan that is not working begins with making sure that the oven is set for convection mode. Press the "Convect" button on the oven's control panel; if you see "Convect," "Bake" and "350" flash on the Frigidaire oven's display, the oven has been set to convection mode. Specify a temperature setting if you are cooking at a temperature other than 350 degrees Fahrenheit and press "Start." Check the convection fan to see if it is now running.

Food Position

It is also important to make sure that you are using the convection part of your Frigidaire oven. Frigidaire wall convection ovens feature two separate oven spaces, and only the upper oven is equipped with a convection fan. You will be unable to use convection cooking in the lower oven; transfer the food you are cooking to the upper oven and test again to see if the convection fan now operates.

Verifying Power

Having verified that the oven is set up properly for convection cooking, the next step is to verify that the oven has an electrical supply. The convection fan operates electrically, so check the oven's AC power cable to make sure it is not loose from the outlet -- if the cord is even slightly loose from the outlet, other electrical components on the oven may still operate, such as the button display and temperature setting controls. If the cord is plugged in and not damaged, check the breaker box to see if the circuit that controls the oven is tripped.

Contacting Frigidaire

In the failure of these troubleshooting steps, it is likely that the Frigidaire oven's convection fan has simply failed, and it will be necessary to contact Frigidaire regarding fan replacement. You can contact another oven repair service, but contacting Frigidaire is typically the better option in case the fan replacement costs are covered under the manufacturer's warranty.
