The owner complained that in the middle of the night the oven would start beeping and the error code E0 -14 was displayed.
I looked online for for what the code was and how to take care of the problem. Two different sources said that I should open the console release the ribbons connecting the touchpad and the control board clean them with alcohol (even use a toothbrush), wait until the contacts were dry and reinstall them and check oven for operation. I did so and the error code E0-14 reappeared. Both sources said to replace the control board if this reoccured. I replaced the board and when turning the power back on the code PF for power failure appeared. I simply set the clock and all the functions of the stove were working.
The next day the owner called back and said the beeping happened again when they were NOT even using the oven.
They had turned the breaker off each time the code would come on. I went back out, turned the breaker on, reset the clock and everything
We had talked about past performance of the oven, the oven they had before, all on the same circuit. They had no problem with the older oven and none with the new one for about two years until the now(The present). The touchpad when keyed in performed
every function when I touched the pad. I thought at first perhaps with the oven heating up or the front burners near the touchpad on
the heat would somehow cause some expansion and cause a short in the electrical. BUT the problem appeared when the oven was not even on.
