I have a double oven Jenn Air where the top oven works fine, but the bottom oven generates a code "Fr" whenever you try to use it (hit bake, enter temp, it seems to want to start working then stops and beeps with code Fr (at least it looks like a lower case R).

I ordered and replaced the temperature sensor which did not help. A useful sign that both the old and new sensors were working correctly is that when the sensor was disconnected, the cabinet fan (not convection fan) on the oven turned on (like the oven was hot).

Anyway, it looks like I still have a problem which is now pointing me towards the relay board. Unfortunately, there are two relay boards listed in the parts so I don't know which one to order (I'm leaning towards the "lower" board since that's the oven having problems).

So my questions are: a) is replacing the relay board the right thing to do at this time and b) which relay board should I replace?

Thanks in advance for any help you can provide.

Conor,

You had it all along, Yes the code "Fr" was in regards to the lower oven sensor or relay board

The lower oven board was not communicating properly to the upper(main)oven control/relay board.

Yes, order and replace the Lower Oven Relay board, leave the new sensor installed(just in case), double check the wiring for loose connections and possible damage, and you'll be alright.

Good Luck,
