The oven in my Wolf cookstove stopped working some time back. I called the authorized repair person who told me that the problem was electrical.
The voltage between each of the two lines and ground is 110 volts each (what it shoud be); but the voltage between each of the two lines and Neutral is only 20 volts. The repair person claimed that this was the probelm and that an electrician could fix it easily.
I had replaced the circuit breaker (50 Amps) to try and fix the problem but that did not help.
