My GE Profile Spacemaker 2.0 started to hum a bit louder and now makes no heat. I followed the GE troubleshooting flow-chart and it points to the magnetron, but the resistance checks (continuity pin-to-pin, open pins-to-case & no sign of any arcing or cracks in magnets). The HVT (hi volt Xfmr), Cap (capacitor) Xfmr, and diode all seem to be okay although my cheaper DVOM shows diode open both ways .. so I used 12v battery with 1.8k resistor in series & get 3.1v one way and 4.3v in other. The new diode that came with a new magnetron had same readings but this magetron was returned .. was wrong # and mounting pattern. So .. my unit draws about 5amps when mag is connected and about 8amps when mag is disconnected. Why more amperage when magnetron isn't connected ? Does this mean anything to anyone ? What should I do next ? I appreciate any help, thanks.

My GE Profile Spacemaker 2.0 started to hum a bit louder and now makes no heat. Followed GE troubleshooting flow-chart .. points to magnetron, but resistance checks & visually looks good. Xfmr, cap, also check good except cheaper DVOM shows diode open both ways .. used 12v battery with 1.8k in series, I get 3.1v one way and 4.3v in other, but new diode read the same (was supplied & returned with wrong magetron). Unit draws @ 5amps with mag connected, @8amps when mag is disconnected. I welcome any input.
