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.

How do I replace the switch for a jennair electric cooktop? model jed8430adb. Thanks!


You first need to remove the unit from its installation. Start by disconnecting the exhaust fan from the ductwork. Then push the cooktop up.

To get at the switch you need to remove the top by taking off only the top row of screws all around the unit and also at the top of the down draft cavity (the down draft cavity is where the grease guard mesh is)

Cold air from outside enters the kitchen through the down draft vent.


its would be best to install a damper
whether auto matic
or manuely operated
this is a common problem for the down draft
ive seen some people install things similar
to dryer vent louvers,
but check you exhaust area and still if you can block direct draft
but dont block it so that it cannot exhaust properly

The jenair made a popping sound, wasn't even turned on. Then found it didn't work at all. Flipped the breaker, and it would immediately flip back, the Jenair would also make the same popping sound.... Do...


I had the same problem. Mine was caused by liquid seeping into the infinite switch (the switch that gets rotated by the knob to set burner temperature). This caused one of the live wires to short to ground within the switch. Bad Design IMHO. Replacing the switch fixed the problem (you can get replacement parts at Searspartsdirect.com - search using the cooktop model number).

How do you get the black top off. I have to put in a new front burner. Thanks.

Turn off the circuit breaker to the cooktop. Verify by making sure the burners/fan do not come on. Disconnect the exhaust fan (underneath the cooktop) from the ductwork by removing the tape that joins it. While you are underneath the cooktop, open the junction box. Label the four wires that are joined so that you will be able to connect them later. Then disconnect the four wires. Remove the metal sheating that connects to the junction box (there is a nut on the inside of the junction box that you loosen. Pull out all the supply wires (from the mains) from the junction box. Then push the cooktop up and out and lay it flat on a table with the flat side down.
Take off only the top row of screws all around the unit. Rotate the unit so that you can get to the down draft cavity (the down draft cavity is where the grease guard mesh is). Remove the two center screws. Then pull the black top off.

Cold air draft


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

Exhaust turns on automatically in burner mode


Hello
I have the one with the 4 burners and the grill, and when the grill in on the fan has to come on, and it does automaticly, but once you finish with the grill you have to change it back to stove mode by putting the 2 burners back or the fan will allways go on when you turn the switch. It is a safety regulation for the fan to be on with the grill to avoid the fumes......I know I hate that too.
Hope this help

JED8230ADB down draft


Please don't buy another one!!! This is the most poorly designed cooktop made. You would be much happier with another brand. If you really want a treat try Thermador. I had a Jenn Air installed on an outside wall and vented directly outside, It still set off the smoke detector constantly. Very hard to clean., Very poor burners both open coil and smooth top.

Installation of new electric cooktop


If you're talking about a downdraft style cooktop, you will just need to measure the discharge vent diameter and shape and match that up. Not all are the same shape but most are 6" diameter
