I have an older wall oven model EB388-610, serial FD7904 36904005307 that had some LED light segments go out. Installed new display board and tried changing basic settings from 24hr clock to 12 hour clock. Also temperature is in celsius. Need it in Fahrenheit.
Followed the steps in service manual but won't work. Tried turning breaker off 15 minutes and then retry. Still nothing happens. Hopefully somebody has some insight on this?
