If your oven won't get up to temperature, it is likely that either the thermostat needs to be adjusted or one of the elements has gone bad. Both fixes take little more than a screwdriver and a few minutes of your time

Place an oven thermometer inside the oven and shut the door.
Turn on the oven, set it for 350°F (180°C) and let it heat for 30 minutes.
Check the thermometer. Most thermostats are accurate to within 25°F (14°C). If yours is off by more than 50°F (28°C), the thermostat is bad and you will need to have a professional replace it. If your thermostat is off by less than 50°F (28°C), adjust the thermostat.

Locate the adjustment screw. On some thermostats, the adjustment screw is on the back of the thermostat knob; on others it's inside the thermostat shaft.

    The process still continue with the below procedure.

    o make a temperature adjustment on the back of a knob, remove the knob
    and loosen the retaining screws on the back, using a Phillips
    screwdriver. Turn the center disk toward "Hotter" or "Raise" to increase
    the temperature, or toward "Cooler" or "Lower" to decrease the
    temperature. Tighten the screws, reinstall the knob and test the oven.
    Readjust the knob if necessary.

    To make a temperature adjustment inside the shaft, remove the knob and
    slip a thin flathead screwdriver into the knob until it engages the
    adjustment screw in the bottom. Turn the screwdriver clockwise to raise
    the temperature, counterclockwise to lower it. Each quarter-turn will
    move the temperature about 25°F (14°C). When you're
    done, reinstall the knob and test the oven. Readjust the temperature if

    Identify the bad element. Set the oven to broil and check the upper
    element. Then turn it to bake and check the lower one. Both elements
    should turn bright orange if they're operating correctly. If one is
    cold, it needs to be replaced. If they both seem to heat up, look for
    signs that one is damaged. It may appear to be melted in one spot, or
    one spot may not turn as bright a color as other parts.

    If you cannot carry the above troubleshooting on your, i strongly advice you get someone who can or perhaps, since you said the oven is new, you can return it with the complain and order for replacement.

    Take care.

    I strongly advice you return the oven with your complain that the oven never get hot or warm, with this, the unit will be replaced because many atimes, there are some ovens with factory problem, so it is advice you return it and order for replacement of the unit from ebay.

    Take care.

I doubt there is a fuse on the pigtail, it sounds like your black wire is grounded somewhere. Check black to red, if you get 120 or close to it, your black is shorted to ground.

I think I can help you but i am a bit confused with the panel box and the junction box. If you want to reply explain the circuit in a bit more detail from the switchboard where the fuse is to the back of the oven. It would also be a good idea to have a voltmeter or test lamps handy. Does the double pole breaker do the Active and Neutral or is it 2 phases going through the breaker. Did the wiring used to be for a full range and now there is only the new oven in its place.

Connecting wiring into oven

The house wiring was not up to code so the white wire was not supposed to connect to the white terminal on the stove. Instead the white wire connected to the red, the black to the black and bare ground wire connected to the white terminal thus providing ground and two termianls with 110 each.

black= 120 volts to ground
red =the other phase of 120 volts to ground
green/bare = ground
you seem to have a 120 volt wiring. you will need to change this wire to the panel from the existing, to # 6/3+ground you will need a 40 amp double pole breaker. THIS VOLTAGE/AMERAGE WILL KILL! If you are not an electician I would recomend hiring one, as, if done wrong the wiring can cause a fire or worse.

Admiral Clean-O-Matic oven: Power cord black red white ground?

Your terminal block has been by-passed .
Hook your black cord wire to the black screw on the terminal block.
Hook your white wire to the white screw on the terminal block. Hook the bare ground to the exterior ground screw.
The 2 wires that are wire-nutted together will have to hook to the red wire on the cord.(they originally went to the third connection on the terminal).
You will probably have to cut and strip the red cord wire and attach it with the 2 wire-nutted connections.

What coloured wires go where on the main oven thermostat

If you are speaking of the 240v connection to hook up the oven to the electrical source, then white is the neutral(white to white), black is one of the 240v hot wires(black to black), and red is the other 240v hot wire(red to red).
Finally there is a bare or green color ground wire that goes to the bare or green wire form your source.
normally, the two outside wires on a terminal strip are the hot wires and the middle onif the neutral(white). It does not matter which wire(red or black) goes to what hot terminal at the appliance.
If you are talking about the internal wiring, I can get you a schematic of that.
