Just purchased and installed a new JED8430 down draft in my kitchen island. Installation was fairly straight forward, as I was replacing an older Jenn Air downdraft.
Three wires to connect, black, white and ground and things seemed to be good. All burners work and light correctly.
When I turn the fan on, it will run for 30-60 seconds and then shut down and there is a terrible burned smell.
Figured it out. I'm not all that mechanicaly inclined. When read the wiring diagram, I saw three wires and assumed they were the black, white and ground. I missed the red wire which was still tucked in the stove. So, the problem was incorrect wiring, and my fan was overheating and the burners were only getting 110. Rewired this afternoon and all is well.Figured it out. I'm not all that mechanicaly inclined. When read the wiring diagram, I saw three wires and assumed they were the black, white and ground.

True. If I hadn't found a sentient life form where I bought the top (Lowes) I was ready to put the old one back in and take the new one back. This guy actually pulled one of the display models out and showed me what to do and wrote some directions. He knew what he was talking about, which means he will probabaly get fired soon and that store will be back to the status quo answer of "I don't know".

I have the same cooktop and the same problem. What did you connect the red wire to? Black? Thanks, MattI have the same cooktop and the same problem. What did you connect the red wire to? Black? Thanks, Matt

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)
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
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). 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

1) turn off power at the breaker.
2) remove hold down screws
3) pop up cooktop out of counter top
4) remove knobs and downdraft grille
5) remove ceramic top (screws around outside and also in side grille opening)
6) unplug burners replace with new burner

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.

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.
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
