I have a Whirlpool double oven (RDB305PDB12). Recently the oven dislplay would go blank and then after several minutes come back on. On one failure it actually displayed the error code F2 E6 (check keypad connector). I removed the controller ribbon cable from the microcomputer board and cleaned the contacts. I put it back to together and everything appeared to be working fine. During the process of using the oven, the display would go blank. After several minutes it would come back on with a power failure indication. I could reset the oven and everything started to work again. This pattern of power failures continues to happen everytime I use the oven. Any thoughts on what the problem may be?
Thanks
