Is it a brand new stove that was installed for the sale of the house?
Could be on the wrong size breaker. I replaced my stove last year and
had the same problem - everything but the oven worked - until I found
out it needed to be on a 40 amp breaker instead of the 50 amp circuit
that the old one was on. Oddly enough, this vital information was NOT
given in the paperwork that came with it. I bought it as a self
install pick-up from Lowe's and had to call GE to find out what
amperage it was rated for.
