Superba convection oven probe display problem

I had a similar problem today with my KitchenAid Superba wall convection oven (2002 model). I was roasting tomatoes at 225 degrees F for 3 or 4 hours when the control pad changed and showed that the probe was in use (never have I used it and had to look for it). I, too, tried to plug in the probe and take it out, but nothing changed. My worry was that I could no longer use the timed bake function. After trying to reset by turning off the oven at the breaker, with no change, I turned on the oven to 400 F and left it on for 10 - 15 minutes hoping that the high temperature would dry out whatever moisture that must have gotten in the place where the probe connects. Then I turned it off and just waited. After a half hour or so the control pad cleared and nothing showed (that is what you want when the oven is off!). Everything is back to working now.

Had the same problem with my 2011 KitchenAid Superba Convection oven after baking two large cut-up pumpkins for 1 1/2 hours, which generated lots of moisture in the oven and in the room.
Then, although I was not using the probe, the oven showed the message: "Enter Probe temp or remove probe." I, too, turned the oven off and on, tried plugging and unplugging the probe, tried actually using the probe (unfortunately in a glass of water, thus worsening the moisture problem.) We cut the power to the oven, but when it was back on, the oven still showed the same message.
Finally, I found this series of posts, ran the oven at 450 degrees for 20 minutes (just to be sure!) and 10 minutes after turning the oven off, the message disappeared. Whew! Thank you!

Good luck with this. Shortly after purchacing mine mine started scrolling "enter probe temp___ or remove probe. This was after I had shut off the oven and cooking complete. In some cases I had not even used a probe. Tried to correct by inserting the probe and removing...no help...tried shutting off the breaker to the ovens and try to reboot...same message reappeared. Tried to enter a Temperature but say for 325 it would not let me put in but two numbers 32.would not take the 5. Under warranty the wiring harness, control board probe jack and who know what else was replaced. No problems for over 2 years and now it has started doing it again!!! Usually if left alone it will clear itself after about 3 hours. HOWEVER on one occassion it cleared itself and oven was off but strated scrolling again on its own then cleared it self again after an hour. PROBLEM WITH THIS IS WHEN THIS IS HAPPENING THE OVEN IS NOT OPERABLE. I DO NOT THINK KITCHENAID EVEN UNDERSTANDS THIS!!!!!!!!!!!!!!!!!

My kitchenaid wall oven was throwing a probe error. After disconnecting the probe connection socket and then removing it from the connector on the control board, it was still throwing a probe error. After taking a look at the control board I found a number of cracked solder connections including one on the temperature probe connector pins. I reflowed the solders to repair the cracks and the probe error went away.

These posts were very helpful. I first searched the troubleshooting section of the manual, but nothing insightful. Came across these posts and decided to try. In my case, set oven initially to 325 as I wasn't given able to increase passed this. Ran for 10 minutes while "probe in" message was blinking and then after 10 minutes or so I was able to increase to 450. Ran for 5 minutes and probe in message disappeared and oven is working now. I've never used the probe.

How do you unlock control five seconds

FYI --- your oven does NOT have to even come with a probe, probe hole, or anything. Somehow the moisture COMBINED with normal cooking contaminates like smoke residue gets into the circuitry on the board itself OR the probe wiring harness/plug and then fools it into thinking that the probe is present. MORE OFTEN, I think that the problem may NOT be the probe socket, but the board itself. If you notice, almost NO ONE complains about the problem for at least six months, after replacing or getting a new oven. It take OVEN USE to create the smoke components that must be added to the moisture, which, by itself, will not cause the problem. So, the more you cook, the more often you will see the problem. Even the self-clean feature might add to the smoke, and cause problems sooner.

The reason this happens when cooking is this: All the probes at room temp have a very high resistance. You can provide a high resistance circuit, just from moisture and contaminants. This circuit can be created on the board itself, OR the probe hole / socket / wiring harness (if you have one). Contaminants and THEN add moisture and this provides a connection, even without the probe. You have just told the oven computer that you have inserted a probe with a resistance of about ? 38,000 ? ohms. (not exact, but when heated, the probe goes to ~ 100-300 ohms.)

I think the fix for this is to trace the probe leads from the harness plug on the board to the microprocessor, (you can Google to find the right Plug # number). Then CUT the trace on the circuit board as close to the microprocessor as possible. Worst case, cut the lead off the microprocessor and then put a spot of glue on it to keep the moisture from touching that pin.

SADLY, the true "fix" would have been to use three, instead of two wires, just like they do with your headphone jack. It opens and closes a connection simply by inserting ANYTHING, including a toothpick. Since this is a known problem, and KitchenAid has chosen the remove any references to the problem, I'm guessing they did this to remove any plausible admission that they knew of the problem. They didn't fix it because it was either too much trouble or expense to fix, (which might involve a recall), or profited in a number of ways. Incompetence is most always the case, rather than conspiracy, but someone could and should and probably could hold their feet to the fire and force them to pay for service calls to correct this problem retroactively.

Here's what I did to fix the problem:

Insert probe. Enter temp of 160F for probe temperature. Select Bake and the select 400 degrees. Remove probe. Hit start.

Let the oven run for 15 minutes after it reaches 400F. Turn off oven, and the problem was fixed.

Apparently moisture from our previous dish got into the probe plug hole, convincing the oven that there was a probe inserted.

I'm guessing that you can enter 160F as the probe temp even without inserting the probe (after all, it thinks the probe is there).

Unable to set the temperature setting on the Bake and Convection Bake higher than 176 degrees it will not go any higher.
