How do you disconnect the ribbon cable from the control Board on Jennair model JES9800AAB/Electric slide-in range with downdraft.

It is possible to remove the downdraft equipment from underneath your JennAir electric cooktop and still use the cooktop, but it depends on how the downdraft equipment is attached to the cooktop and whether there are any other issues that may arise from removing it.
Before attempting to remove the downdraft equipment, you should consult the user manual or contact JennAir customer service to ensure that it is safe to do so and to obtain any specific instructions for your particular model.
Some potential issues to consider when removing the downdraft equipment include:

1. Airflow: The downdraft equipment is designed to help draw smoke, steam, and odors down and out of the kitchen. Without it, you may experience reduced airflow and ventilation, which could result in lingering odors or smoke.
2. Heat distribution: The downdraft equipment may also help distribute heat evenly across the cooktop surface. Without it, you may experience hot spots or uneven cooking.
3. Stability: The downdraft equipment may provide additional support or stability to the cooktop. If it is removed, the cooktop may become less stable or secure.

If you decide to proceed with removing the downdraft equipment, it's important to follow all instructions carefully and to take appropriate safety precautions. You should also be prepared to address any issues that may arise as a result of the removal, such as by using an alternative ventilation system or adjusting your cooking techniques to compensate for any changes in heat distribution.
If you're unsure about whether or how to remove the downdraft equipment from your JennAir electric cooktop, it's best to consult with a professional technician or contact JennAir customer service for guidance.

JennAir F code 9

F9 Door lock safety circuit on power relay board sensed Replace power relay board

F7 stuck keypad
Stuck keypad may mean relay is turned on.
Determine if problem is with the Key Panel or Control by:
1. Pushing CLEAR/OFF pad.
2. Disconnecting Ribbon Cable from control and waiting at least 32 seconds to see if Code recurs

If code recurs, problem is in the control. Replace control.

If code does not recur, problem is with the Key Panel.

Unless they start working again after it has a chance to dry out the touch panel will have to be replaced. This happens when excess moisture gets between the very thin layers of the membrane.

hi there,

initially downdraft ranges from 6oo CFm to 1600 CFM within the pushbutton control.

CFM means (cubic feet of evacuated air per minute)

Hope this initial info/idea helps.

Let me know for further clarifications,

I would double check that the installer used the correct vent hood outside. The correct one has a spring that keeps the outdoor flap closed when not in use. Cleaning the outdoor flap area may also help it seal a little better. Even if the right hood was installed, you might check to see there is a spring present (or signs that there was one.

I have never had air blow out the downdraft, but I do feel cold travel to the fan unit which makes the floor cold in front of the range.

Your control panel is getting ready to quit. Mine did the same thing, I ignored it and now nothing on the touch panel works. About $150.00 for the part.

open the door on the left side low down you will find the model and serial number .

Replacing this top is not too difficult. It is secured by four screws on each side. You might have to remove some of the flanging in the back to pull it off. Make sure to unplug the the unit. I would think that the top might be pricy, but if you take your time replacing it should be no problem.
