Thanks for the replies.
1) Using your volt meter check for the following voltages:
A) Inside the electrical panel, measure for approximately 240 volts on the 2 screws at the double pole circuit breaker. Also at the breaker, measure for 120 volts on 1 breaker screw hot wire to the neutral bus bar and measure for 120 volts on the 2nd breaker hot screw terminal to the neutral bus bar. If the breaker is working correctly, you will measure voltage at the breaker with these 3 different measurements.
B) At the wall receptacle, measure for 240 volts on the 2 middle vertical slots. Measure for 120 volts from 1 vertical slot to the bottom neutral slot. Move the meter probe over to the 2nd middle vertical slot and measure for 120 volts to the bottom neutral slot. If all 3 good measurements, then the circuit is wired correctly.
C) At the double pole breaker, there should be a red and a black. At the neutral bus bar, there should be a white and a green or a bare copper. Your W to G (Neutral to Ground) measurement suggests a loose neutral or wired incorrectly. N to G voltage should always = 0 volts or close to 0 volts.
D) The receptacle may be wired incorrectly. I am unable to determine from the back of the receptacle.
Red and black terminate to the 2 middle slots (X & Y). White terminates to the "W" bottom slot opposite the round ground hole. The bare copper ground terminates to the round ground hole (G).
Refer to the wiring diagram I originally sent you.
NEMA 14-50R Receptacle Wiring
W = white neutral
X= Red or black
Y = Red or black
G = bare copper ground
If your AC voltmeter has a built-in audible continuity feature, you can use it to check for a possible cut cable.
Let me know if the range now works correctly after making the corrections...........Thanks...........Kevin:)
