Did replacing the control board fix the problem? I have the same issue. JTP15 built in oven, get codes F2, F3 and F5 during bake operation. Even got an F2 when the oven was not baking ( it had power to it...i.e. the clock was on). Tired shutting breaker off for a minute...still get F2, F3, F5 when baking.
