Troubleshooting Range Cord Wiring
I'm hooking up an electric range using a 3 prong cord. The terminal block is just as shown in the above drawing and I hooked it up with the cord as shown. I can get power to the range eyes but not to the oven or control circuit for the oven. The range has three wires hooked on the red terminal (two are connected to a single connector) and one single red wire. The black and white wires and ground tab are just like the drawing. The black wire terminal, white wire terminal and the two mounting block screws all seem to be connected as I can get a circuit path when testing with a meter. I don't get a circuit between the red terminal and any other point I try. I have checked the receptacle and power cord and they are both ok.
Do you have any other suggestions as to what is wrong.
Thanks,
BC
Hi BC, It seems that there is power at the unit because the cook top portion is working ok. I would suspect that either an oven control is not working or that maybe a wire has become disconnected. If the range is used and not brand new then I would check all the internal wiring and connections to the controls. If there was a previous owner, I would contact them and get some history about the performance of the range. A continuity meter would be very helpful for testing between the terminals at the cord connection to the controls for the oven.

Questions about Wiring a Range
Question from Don, a Homeowner from Morgantown, West Virginia:
How do I connect the red and black wires for the range?
I have a 3 wire power cord for a new electric range. The wires are not marked as red or black. How do I know how to connect it. I know the middle wire (unmarked as well) goes in the middle.
Dave’s Answer:
Connections for a 240volt Range Circuit.
The circuit power wires for a 240volt range may be used for either of the circuit power wires, so it really does not matter, the power connections will work either way. However make sure to positively identify the ground wire of the range circuit and identify it as the ground wire with green electrical tape and make the ground connection.
