The oven indicator light blinks twice, heating indicator light blinks twice, repeat. How to replace Electronic Pc Board. Ordered an new Control board here. Killed gas and power supply. Pulled oven. Opened rear bottom panel. Labeled all wires to control board with “new” locations using electrical tape. Included instructions were great! Pulled all cables. Removed old and reinstalled new control board. Attached all wires to new locations. Tested... Success! Better than ever. Board replacement time - 3 hours total.
