This is a general answer and not specific. The oven thinks is still in the cleaning mode. If it has one, push the clean button again. Set the oven to a regular bake cycle.

We've had a Jenn-Air wall oven & microwave, Model #JMW9530DAS for 9 years. We never had any problems with it except for the irritating dust that collects between the oven glass. After returning from a 10 day vacation, we got a 1c2c error code when pressing "Bake." The oven worked fine before we left so we were baffled. We tried other settings like "Broil" "Convect" to no avail. It kept telling us to call for assistance. We tried shutting off the power to the unit for a few minutes but got the same 1c2c error again. So we called a local appliance repair shop (associated to the appliance store we purchased the unit from) and paid a fee to have him assess the problem. He really couldn't pinpoint the problem but suggested it "could be the membrane or the controller." And, to top that, he said Jenn-Air stopped making the membrane but they are going to start making them again and we could get one in 6-8 months at a cost of $500. So now we were looking at a $300 controller & possible $500 membrane....plus labor. We were so frustrated that we decided to tackle the problem ourselves before going out and buying a new oven. We shut the power off and tried pulling the oven out of the wall. Too heavy. After about 20 minutes of the power off, we turned it back on and decided to use the "SetUp" feature as if we were using the oven for the first time, following the directions in the instruction manual. We stepped through the process (clock, auto convect, language, C/F, etc...) then pressed the "Convect" button (instead of "Bake") and voila! It worked! After the Convection Bake Preheat worked successfully, we pressed "Bake" and it worked, too. We just saved ourselves over a thousand dollars as we were going to get rid of the piece of junk. So, before you give up, try turning the power off for a half hour & use the SetUp key and walk through the process.

jenn-air electric wall self-cleaning oven 27 inch. Mobel # w130w. I need to see the knobs to set self-clean

It would seem that the oven is small enough that a fan to flow the heat from the unit would be in use for both convection and bake modes. Usually convection ovens will have a "burst" of fan action during the bake process and it is not a steady fanning of the air that would dry out your cookies, ect. I have a small oven / microwave and my larger oven is a GE that has the "burst" convection that I described. Might not be that much help, but it's hard without more info on your unit. sometimes the model is behind the oven door.

throw the jenn-air out.
purchase something from another company that cares about their products.
I have had the same issue, twice. my wife managed to melt the touch pad by baking and using the burner at the same time. this has happened to countless purchasers of jenn-air **** appliances. they should be sued and forced to fix their faulty design

After the lock indicator light goes out, move the door lock lever to the left. The oven door can now be opened. Turn the selector and temperature knobs from clean to off AFTER THE DOOR IS UNLOCKED. If the temperature knob is turned to off BEFORE the door is unlocked, the door will not open. Forcing the lock will damage the lock mechanism. If this should happen, return the temperature knob back to CLEAN, unlock the door, THEN turn the temperature knob off.

reset your breaker reprogram the clock try again what happend last time it was working self clean broiling etc

Most likely its the EOC (electronic oven control), it needs to be replaced. If you self cleaned the oven a lot the very high heat generated fatigues computers in modern ovens.
