My dual wall oven randomly turns off heating and at the control panel for 1-4 minutes, then turns back on by itself. I just need to reset the clock by the time that was lost. It seemed to first happen mostly when in use, now is also happening when it isn’t in use, so I figure that rules out overheating.
When the display is off for the 1-4 minutes, the oven light still turns on in both ovens. So I don’t think it’s a power issue. I turn the power on and off on the breaker when it turns itself off, but that doesn’t reset it, you have to wait for it to turn back on, on it’s own.
I already tried replacing the control panel with a refurb, but it only got worse (resetting more often).
Did you replace the control panel/keypad or the control board/timer.
The problem is most likely on the control board.
Perhaps try the following.
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.
