|    Microwave oven woes...    |
|    07 Apr 17 17:53:06    |
      From: noone@nospam.com              A client left a faulty microwave oven at my friend's shop, I opened it       up and first thing I checked was, of course the HV fuse. It was open so       a new one. Nothing. Checked with my HV probe, at the transformator       secondary 3.5 kV(AC). At the magnetron nothing, no DC at all. Thought it       was the HV capacitor or the HV diode.Took them home, measured the       capacitor with my capacitance meter, 1 μF ok. Checked with my insulation       tester that can put up to 1000 volts, the diode, forward bias 0 Ω,       reverse bias >10 ΜΩ ok.Of course I didn't do anything as when you repair       household appliances you must be absolutely sure you'll repair it,       there's no room for experiments.Anyone with a brainwave? Again, the       trafo AC ok, DC nothing-something wrong with the magnetron?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
