| Good idea to call an electrician but if you have a multimeter you could do some tests while wearing shoes. Touch one probe to exposed metal on the microwave and one probe to stove. Then check each to a good ground. Wear rubber soled shoes and don't touch any bare metal. Shoes may not protect so don't touch is your real protection.
My guess would be a loose or disconnected neutral on a three wired stove. If your tests show it is the stove turn off the breaker till the problem can be fixed. |
