2, 3, or 4 wires?
I just purchased a new whirlpool wall oven which has 4 wires (black, white, red, bare cooper)
The line coming from the wall has 3 wires (black, white, bare cooper)
The oven that I removed also had 4 wires (black, white, red, bare cooper) however I failed to note the configuration of the wires before I removed the old oven.
Before I install the new oven, can someone tell me which wires are connected to which?
