some of control numbers stopped working, oven now comes on at 375 by using numbers 1&2 i raise or lower, timer only works by using numbers 7&8
after a long on & off power surge, all numbers worked for 2 weeks, then back to 1&2 7&8. Feel that control board is a little expensive, but not even sure that is problem. Confused because everything worked for awhile.

Here are your parts Replacement parts for General Electric JBP85WB4WW Electric range | AppliancePartsPros.comTry removing power from the unit to see if it will again reset and work OK. If it does then odds are it is the control board. The problem does sound like a control board problem and they can go intermittent. I would try the following but it is a bit of a long shot given your symptoms re: the control board is not interpreting the input from the keypad correctly. It is not that just a few keys do not work. Connector Cleaning / Checking Unplug the unit Open it up Remove the ribbon cable from the keypad to the control board at the control board. Clean the edge connector. Use electronics contact cleaner or isopropyl alcohol. If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive. Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here. Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates. Reconnect everything and give it a try. |

Is there a link for instructions for opening the top of oven up ?

Looking at section 2 in the parts its looks like you just remove the rear panel. |
