Top oven works fine but the bottom oven nothing. Works but convection fan does start up. Both circuit boards have been replaced 7 years ago and all was fine till now. Does the bottom circuit board need to be replaced again?
ANSWER Hello Ralph,
You may want to check your lower oven thermal fuse for continuity. If the thermal fails the lower oven will not work. Also check for voltage at the relay board to make sure that you are getting power to the board and out of the board. If you are not getting power out of board but have power to board then you would have a bad relay board.
