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.

Hi. To take care of the upper oven problem you need to replace the upper relay board Part number: 74006612
For the lower oven first check the resistance of the oven sensor. With the multimeter set to 10 Kohm at room temperature normal reading about 1100 ohm. if the sensor checks OK - replace the lower oven relay board Part number: 12001914

Ordered the upper board, not sure where its is located...do I have to pull oven out?
The lower, yes it needs a new board as well, the element test ok.
So any help on the location of board would be great.

Hi.
Most likely you should remove the oven and open the top. The relay boards are on the side walls (wall). The upper board has more relays in it.

I have a older double stack Jenn air wall oven... When the breaker is turned on the oven starts automatically and does not regulate temperature... You cannot shut it off... Heats to over 650 and beeps because it is over heating... The lower oven functions as designed

Its a stuck relay either on the main control board or relay board if it has one. I don't know because you didn't provide a model number. You'll need a new board or a board repair.
