We have a double wall unit Jenn Air range....for a while now the lower unit would show a 'Fr' fault when turned on. The upper one worked fine until recently.

About a week ago it seemed to be taking a long time for the oven to get to pre heat selected temps..but didn't pay a lot of attention to it. Then this morning when trying to use upper oven we selected the temp and it just showed 100 degrees and never got hot....I tried the broiler and same thing, didn't work.

So now we have two probs, 'Fr' fault on lower unit and upper one oven and broiler do not work.

Any help? I think Fr means a circuit board? Thanks in advance.
