Our cooktop finally died.  1964 model.  All of the burners had been replaced many time but now the switch box fried.

Found a new one to fit the hole but not sure about the wiring.

Old one and house has black, red, white the new unit has black, red, green
How does it go together?

Hi,

I would check it with a volt meter just to make sure, but this is what I would expect to find.

Old House:

Black Wire: Has voltage on it (hot wire)
Red Wire: Has voltage on it (hot wire)
White Wire: Neutral/ground - Has no voltage on it.

New Unit:

Black Wire: Wire to the other black wire from the house. (voltage)
Red Wire: Wire to the other red wire from the house. (voltage)
Green Wire: Wire to the white wire from the house and ground it out to the junction box.

There should be instruction with the new unit on how to wire it too.

Wow, that's older then me.

What brand was it?

It was a GE

I rembember once my dad found out how much new burners were because the inner was bad on one and the outer on another.
He told the appliance store he was buying one new burner and going to put the outer ring on one bad one and the inner ring on another and they said that it couldn't be done.  That was twenty years ago and I guess they were right because now I have to replace it.

I would wager a doughnut or 2 that the new cooktop won't last 45 years like the old one.    They don't build them like they used to.   I have a section of our town with a lot of cooktops and ovens 50 years or older.    As long as I can get parts,  I'll keep them running.
