My down draft fan stop working and all others worked until today known of the burners or oven works. I beleived the downdraft board is out.
Answer Hi Robert. The downdraft relay board is part # 12001694. It is mounted on the back of the unit. It is advisable to also get the heat shield plate part # 3604M302-51. Also the oven thermostat part # 74009837, is mounted on the back. It needs to be bypassed to see if this will bring back the oven element power. It will ohm closed if good. There is another main power relay board mounted beside the down draft board. It is part # 12001689. You can also follow the wiring diagram (behind the lower kick plate or behind the controls. This will show you the correct relay to test for 120 vac output to each device. Did you recently use the self clean mode ? If so then the abnormal temperatures 900°+ may have opened the boards. You also need to ohm out the oven sensor for 1080-1,100 ohms. Wiggle the wires as you test it to make sure there are no opens or shorts. It is part # 12001656. Thank You.
