I used my grill for the first time, & the downdraft didn't work we'll, the house filled with smoke & eventually the downdraft shut off and I had to finish cooking in a pan. My Jenn-Air is 2 years old. I had electric before and it worked very well.

You can't modify gas appliances.

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.

Are you sure it is fused, don't think so.

It is fused through the house breaker box.

I had the same problem with the 45" Jenn Air downdraft cook top. The installation of the ductwork from the stove to the outside of the house was not properly installed. The stove is appr 18' from an outside wall and the flow of air was hampered by
too great a bend in the ductwork at the point below the stove on the underside of the house and the pipe going to the outside wall. I believe that was corrected with more curve in the vent work, making for a smoother flow of air. Make sense?

The poupose of either is to eliminate any smoke created by the range or grille and move as much of the cooking odors to the outside. I wouldn't use both at the same time, but if the hood is vented to the outside, it would be just fine to use only the hood. Aregular cleaning will be necesssary. The downdraft has limits as to the distance it will efficiently exhaust air. Flex hose should not be used. And excessive bends or vent length, cuts into the efficiency.

Typically the Jenn-Air has a grill on the left hand side and the fan is suppose to come on when that burner is turned on.

i bought mine new from HD. Neither the dd cover nor grill grates have bushings on them. however thats a good idea.

the only way is to block off/check the flapper., if your not going to use for the winter you can disconnect the vent from under the cabinet temporaily and close off there till you can gain access to check outside grill

bibman: Sounds like the control switch or possible loose wiring. Take the element out and test the slots for voltage. You should get 220 Volts when on high.


DMA Jennair The fan motor is bad and needs to be replaced.

I suggest a new cooktop as THIS IS THE WORST DESIGNED COOKTOP I HAVE EVER USED. Not enough power, very hard to clean,
