Thanks senior electronics repairer, Ulbrich. Though not paticularly efficient electro-mechanical switches called relays still find their way in modern electronic circuits. A relay that fails while in a state of relaying voltage may cause so much damage to an equipment. I learned this from car electrical and electronic operation systems, where mostly blame is shifted to a bad relay when a cars "computer" gets "roasted" .In your oven repair case, you had no choise but to replace a fake faulty relay with another one. But you are not very sure of a long time service of the oven. One day I lacked electricity due to a failed relay in my supply meter, but couldnt replace it due to restrictions by electricity supplier that, only them should open the sealed meter. You look younger than 80 years in that photograph making me to doubt if you are indeed older than one of the regular article contributers on this website. I hope you are passing your immense knowledge of electronics repair to your loving grandchildren

In reply to Tito Kanshulu.

Thanks Tito. I did really appreciate your flattering comments. With this rare problem I had the opportunity to spend more time and replace only the relay, and not the entire board. Nature will be thankful and this made me happy.

That is even better Henrique because the enameled thin wires prevents short circuiting on small surfaces also when they cross each other. And the fact that the wire is so thin may also protect against way too high currents to protect circuits from getting more damage!
