So I go to a service call this morning and I am getting 120v between range and sink. So I shut off the breaker and pull out the range to remove wiring cover, I assumed the bonding jumper was not in cause it is a 3 wire range. To my surprise it is in and everthing seems to grounded OK. I turn the breaker back on and the short will not return, I tried everthing to get it to come back with no luck. I checked the ground on the dishwasher and the garbage disposal and everthing seems OK.
I thought maybe the sink was becoming energized somehow (its hooked up with plastic water lines) but it too seems to be grounded. I get 120V from a near by plug to the sink. From the ground on the near by plug to the sink I get approx. 2000 ohms.
So everthing seems to be grounded OK. I think it was the range that was becoming energized as it went away when I turned off the breaker. If this is true why would it not open the OCPD.
The range did appear th have some damaged wiring inside and the clock and two burners are bad. The damaged wires that I saw however did not appear to be touching the case of range but I did not take the range totally apart cause I am not a range mechanic.
So my question is if everthing is grounded why did yhe OCPD not trip, Why would the short disappear, and how can I be certain its a range problem?
