ok here is what is happening. got a new oven and the display will not work, the burners do. called a tech out, and he says there is a voltage issue with the house, bad neatral. I check voltage at the plug, 120v phase to neutral both legs, 240 between phases. plug in the oven and I get 240v phase to phase, 240v from one phase to neutral, the other leg appears dead. took the whip off the range/oven and hooked a incadesent lamp between one phase and neutral to test neutral. the phase the light is hooked to drops out and shows 240v on the other phase, and phase to phase. is this a bad neutral or breaker?

You have a bad neutral somewhere. Everything will read fine unless their is a load. If you get 240 to neutral then I bet you get 0 to neutral on the other phase.

Are you using a solenoid tester or a digital meter?

Just had this happen last week. Connections all looked fine, turned out to be the SE the range was fed with had been laying in water under the house and the neutral strands were crumbling apart in the middle of the run. Wasnt a problem until they got a new stove with digital display
tried to hook the light up to the circuit at the plug after i had the problem with the cord. all the same stuff still happened

Is this three wire or four wire?
Do you have a ground wire to work with?

Are you sure there isn't a problem at the pole or at the service? or is this problem just about the range-- if so then you have a bad cable or some connection in the range etc.

3-wire, no ground
If you are not an electrician, don't try this.
Try reterminating the cable in the panel with the white wire as one of the hots and the black as a neutral and see if the readings are the same.
If you smell something burning, turn it off.
Make sure the receptacle is disconnected, if it's a
3 wire the ground might be connected to the yoke.

Put it back right away!

Did you try to eliminate the receptacle from the occasion? (Equation) fixed it for me

:eek:

Before I did anything of this nature I would be using a continuity tester instead.

Great Call! Had a hand hole in customers yard that constantly got flooded. Connections oxidized to three times the size till it failed.
