I have a control board that starting showing an error on screen. I replaced the control board, however, the clock runs 11 seconds fast. I sent the board back for a replacement and when the new board arrived it exhibits the same problem. If I run the countdown timer you can tell it's clicking too fast. A 1 minute countdown takes 48 seconds.
I can't believe both control board would arrive defective with the same problem. Someone told me it was the control board transformer. I tested (ohm) the winding and one was good the other seemed a little lower than spec. I have replaced the transformer and still .... clock runs fast.
Please tell me the control board received it's clock timing from the 60hz AC line and a bad filter board is most likely the culprit for the incorrect timing.
ANSWER Hello Rich,
The suppressor and line filter would not cause the board to be 11 seconds fast. This would be either in the time circuit or in the home wiring. If the hertz coming into the unit is not correct then this could cause a faster or slower time count. If the wiring is correct then it is in the timer circuit on the control board.
