we just installed an older model Jenn-Air electric wall oven. My husband connected these wires together: black/black, white/white, red/red and green/copper was this correct? The stove does not heat but the light comes on.
No. Get a kettle or saucepan and try it, you'll see
it depends on the amount of nickel in the stainless.
Have you tried the broil setting? If the top gets hot on broil but nothing on the bottom on bake then the bottom heating element is bad. If nothing either way then there is a wiring problem since it's unlikely that both elements would be out. If you have a multi meter, carefully measure the voltage at the plug, across the black and red should be 240 volts and black to white, red to white, black to green, and red to green should all read 120 volts.
He got the colors correct. Now double check to be sure they are making good contact under the wire nuts. Then make sure the breaker is wired correctly and passing voltage on both poles. If it still doesn't work you need to look deeper into the controls on the Jenn-Air. A blown fuse? OH, I just remembered something I have seen more than once in older panels. Someone May have used the white as a hot and the red as the neutral. That would explain why the light comes on but no heat. Do be careful. Turning the breaker off/on/off/on etc. can be tiresome but get it wrong just once and you will regret it. Been there.
As you describe it, your wiring is correct for a 220 volt AC connection. Trip the breaker for the oven. Disconnect the oven, reset the breaker, check and verify the AC voltages between the following lines: white - green/copper 0 volts black - white 120 volts red - white 120 volts black - red 220 to 240 volts If your measured voltages are not within 5 volts of those indicated, you have a wiring problem. Go to your service panel and ensure that the connections to the oven breaker (trip it first) are tight. WARNING: Hazardous voltages are present in your service panel. Do not touch any metal parts other than the case of the panel, and the neutral or ground bar. Reset the breaker and measure the voltage between red and black at the breaker terminals. If it is not 220 to 240 volts, you have a bad circuit breaker. Replace it with an equivalent type of the SAME trip current rating. If the voltage at the breaker is correct, measure black to the neutral bar, then red to the neutral bar. Both these measurements should be 120 volts. If either one is wrong double check the connection of the white wire to the oven at the neutral bar. It should be tight. Check the wiring at the oven connection again. If it is still wrong, you have a wiring problem between your service panel and the oven. Call in a licensed electrician to repair the wiring. If the voltages are correct but your oven still fails to operate properly, your oven is the problem. Pull off the rear panel and make sure the main, neutral, and ground connections inside the oven are clean and tight. If this still doesn't correct the problem, call in an appliance repair technician to service your oven.
