Jenn Air W256B error code F8

Hi, F8 on later model jenn-air ranges/wall ovens indicates an issue with the meat probe, usually the resepticle. The fault is sensing a temp. at the probe above 250. Unless you actually have the meat probe inserted into the recepticle and the oven has heated above 250, then it's not likely the meat probe itself. Hence why the recepticle is likely faulty or in need of inspection/adjustment. Here's how (this may or may not work...sometimes it does though). First unplug the range or shut off the power to it. **The probe is attached on the oven liner via a nut, however you,ll need to gain access to the outer side of the liner by removing the side panel if the recepticle needs to be replaced, but hold on.** You nay only have to loosen the nut and re-tighten it to insure the recepticle has a good "ground" to chassis. there is only one wire attached to the other side (you can't see it) because the probe converts temperature to resistance in the control, that is why this "ground" is essential and can cause "faults" if not secure/sufficient. At times that's all it takes to force an F8 code. Try this first, reset the power and see if it yields a successful remedy. Hope that helps, good luck Hope that helps, good luck
