Recently the top oven on my Jenn Air WW30430W stopped heating properly. It would take a long time and the temp would rise and drop even with the door closed. I confirmed that the heat sensor was good so I replaced the burner element. After doing this there was a soft high pitched sound coming from the relay board. After a few minutes it would stop and the oven appears to heat properly but the high pitched sound does come and go intermittently. Is this an indication that the relay board is going bad? I did get an F5 errror code once but that went away after turning the oven off and back on. The bottom oven seems to function properly.
ANSWER Chris, The F5 error code, and the high pitched noise from the relay board, and the erratic oven temperature, would indicate an issue in the relay board, "F5 - Power element relays disabled in cook mode - 1) Intermittent sensor or wire harness connection. 2) Intermittent contact on PRB." 74006613.Since you tested the sensor and replaced the element, you're relay board is the next step.
