Microwave oven

70 volt to microwave plate

Hello friends. My microwave gave me an electric shock. With the pole search, the light turns on, warning me that there is a leak of electricity. I measured with the amperometric clamp and between the microwave and neutral plate it measures me that there are 70 volts. could someone tell me why this occurs and if it is dangerous? Now I'm going to take it apart to see if there is anything to mass. But it really catches my attention that it's only 70 volts and I don't skip the therma Thank you very much in advance

Hello, it can be the high voltage transformer that is partially leaking, since it has a winding that joins the carcass of the same traffic.

Take out the entire frame of the chassis and I still have the same problem. But this fault is presented to me with the microwave plugged in, it gives me 140 volts of discharge and plugged in, but without 70 volts of discharge being in progress. Any other suggestions??
Thank you very much for your help!!

it may be that the transformer is derived from amaza you have to measure it first disconnect the microwave from the power grid then remove the wires from the primary of the transformer then measure each connector with the microwave plate

First thank you very much for the help.
Disconnect the entire tranfo and remove it from the housing. I plug in the microwave and continue to turn on the search for poles and measuring voltage I still have 70 volts. I'm going to see how to disconnect from a piece and see what happens. The microwave has a grill

Simply what you said to go disconnecting is the most logical and successful thing you could do, I think that without taking anything out simply by removing all the terminal connectors that feed the components and then go testing from connector to connector with respect to mass because what you say it is simply that a voltage is being derived to ground but it is not so strong because it does not directly if not through some resistance on the road so to measure this continuity you must put the test on a considerable scale or do it with a light bulb test and the connector that gives you continuity with the microwave or ground chassis will be the one that is causing the problem carefully and if it is not a simple cable with broken insulation.
