Jenn-Aire Electric Cooktop Model JED8430BDS

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.

The downdraft is electric so there must be something malfunctioning with it. It is a high volume downdraft fan that is to be vented to the outside. Could it be that something has clogged the vent hole up, not allowing the fan to evacuate the smoke?

While I am not a big fan of Jenn-Air, their fans are usually high quality if they are installed correctly, with the proper vent lines.

IF THERE IS NO COLOR FLEX ON THE COPPER WIRE THEN CONNECT THE BLACK WIRE TO THE RED .

Looking up the service manual - it is no longer available.

Hope this is helpful.

Thanks for using FixYa!!

You can get a new cooktop surface from Maytag/Jennair for $229. It is a pain however to replace it. Where is the crack in your cooktop and does that crack pass directly through a heating element? If not, then you may be able to repair it. I broke the corner off mine, and then dropped the piece (now 5 pieces). I was able to bond them back together and you really can't tell it was ever broken. But, it takes some work.

I can't imagine directing the downdraft vent back up to a traditional hood type system. Why bother, just don't use the downdraft or get a cooktop without a down draft and save money.

In granite, yes for any cooktop as long as someone can cut the correct size hole. Cooktops must be installed so the top is just about flush with the countertop. They all come with a template for cutting the right size hole in the countertop.

As long as the pan bottom is truly flat, you sure can. Hope this helps!

Be sure the control is set to F* and not C*.

always unplug electricity before attempting to repair on any electrical appliance

How do you get the inside area of the vent clean from the grease and oils where the filter is?? I have a rectangular box style downdraft that the vent goes into the floor, I pulled the filter, but the box is to slender to get an arm into to scrub the grease....... does the bottom come off, or is it a sealed unit? How do you get all the brease from the bottom if you cannot reach it?

Hi
I have all the diagrams for that model and will gladly send them to you all for free via email. Remenber that the fan will always get gresse and have to be clean, also keep the filter clean.

Let me know were to send the diagrams...Glad to Help!!
