I have a MCC4060E microwave / oven, when using as a grill or oven it trips the main house RCD but only when opening the oven door, the microwave works perfectly with no problem. It does not happen every time. Any Ideas?
still sounds like the element. prob got a problem on the neutral side of the element. when you open the door you may find the element gets fed 2 lives which stops it working but blows your trip
megger the elements but disconnect first. if they are ok get them hot and try it then
