How to Troubleshoot a Shorted Out Frigidaire Range Circuit Board

Look at the display on the control housing for an error code, indicating a problem with the range. If the codes "F0," "F1," "F5" or "F6" are displayed, you must replace the range's circuit board.

Test the oven sensor if the error codes "F2," "F3" or "F4" are displayed. To test the oven sensor, pull the range away from the wall and unplug it from the wall outlet. Remove the screws securing the lower rear panel and then remove the panel. Disconnect the oven sensor wire harness, located on the right-side of the rear of the range.

Set your multimeter to the lowest setting for Ohms of resistance and then calibrate the meter, following the owner's manual. Insert one probe into one of the terminals on the sensor's wire harness and insert the other probe into the other terminal. If the meter shows a resistance of 1,000 to 1,100 Ohms, the sensor is properly functioning, indicating an error in the range's circuit board. If the meter shows any other reading, replace the oven sensor.

Turn on the oven using "Bake" mode to determine if it is functioning. Turn on the oven using "Broil" mode after testing with bake mode. If one mode fails to heat the oven cavity while the other functions as normal, replace the heating element. If neither element heats, replace the circuit board.
