Jenn Air cooktop has 4 wires Black, white, red, and green and my house supplies power with 3 leads white, black , & green. How are the wires hooked up to power the unit?

Hello Ken,
What color are the wires i suspect they are red,black white,green or bare copper??


connect all the reds to the reds from the house wiring same for the black and white and connect the either green or bare to the green or bare wires

Hello,

I suspect on teh wiring from the house the black&white will be the hot wires and the bare will be ground/neutral

use a volt meter before connecting tonew cooktop and check for;
black/bare to have 120volts
white/bare to have 120volts

if that is what you find...connect new cooktop as such;

black to black
red to (house) white

(cooktop) white and green to bare

Hi,
No, hook the stove black and red to the house black...
white to white and green to green...

depending on your local electrical code:and I see that the unit is 240 Volts A.C., then RED=Power/Black=POWER(L1 & L2)/WHITE="N"Neutral/and GREEN=SAFETY GROUND,on the new unit, then use from the wall power BLACK = L1 and White= L2. then on the unit RED=L1 and BLACK=L2(either way you hook these 2 up there isn't a polarity issue on these 2 wires) on the units hook-up/then use the BARE supply wire as neutral and tie BOTH WHITE and GREEN from the unit together to this BARE wire

Attach it to white or any ground screw.

I just looked, and there is not a wiring diagram available on the web for this unit.

I am concerned about the black with red stripe to red.

Check to see if there is a wiring diagram somewhere on the unit (there wasn't one in the installation instruction or manual for this unit.). I believe the red wire on the house side goes to the black/black wire on the cooktop side (so I believe you are correct on your concern.).

House side green should be to the coiled silver cooktop side silver wire.

But the wiring diagram will confirm these things.

I think the black/red stripe is for the blower.

those wires dont go to the down draft. those colors are to hook up the stove. do you have the instalation instructions?

 You have Red and Black HOT wires and a Green Neutral - That is 220 volts. From the wall - Black is Normally HOT and White is Neutral. That is 110 volts. If that is a typical household outlet, is will only supply a demand at about 15 amps while running at 110 volts. Your Cooktop will most likely demand somewhere around 50 amps at 220 volts. - Short Answer - You will need to have a 220 volt supply line ran to the cooktop from the breaker. Easy to do but dangerous if you are unfamiliar with high voltage.
