Blowing fuse, relay knocking rapidly every second!Shorted high voltage transformer. To test the interface board of this microwave model, you must leave the connector that comes from the door switch connected to the power relay and release the black wire that goes to the transformer, as a sample of the mains voltage goes through the lower contact of the relay!or if you choose to insert any other load, such as a lamp, instead of turning on the transformer.Replace the high voltage transformer (if possible) or adapt the complete set of another microwave to it, for example: magnetron, capacitor, transformer and fuse!Lucas
