sometimes there is a fuse on the main board

another thing you can check. there is a mains supply to the inverter board. its a 2 pin connector. disconnect and see if you get 240v when you activate the microwave

there are only 3 connections to the inverter. mains in, 5000v dc plus heater voltage out and a small data cable

was the inverter new ?

It is definitely worth checking the fuse on the board. If the inverter has failed, that has most likely blown the fuse.

Success!

Fuse in Module had blown – Fitted a 10 Amp fuse to test, and all well.

Markings on original ESKA fuse M 8/250 G and I wonder if 8 refers to 8 Amps?

Thanks again to all feedback, and help.

very good so was it just that all along ?:o

Well, without refitting the faulty inverter/power module, I can only surmise that it blew said fuse when it failed….

will tell you now the inverter is dud

if the mag only fails it does not blow the fuse
