Question about GE XL1800 1100 Watts Microwave Oven
We just realized the polarity of the outlet that feeds our microwave was reversed. Can anyone hypothesize on whether this could be leading to HV problems? The MW produces a loud humming/buzzing, no heat. The dome on top of the magnetron shows some charring. Have replaced magnetron once already.
The polarity won't matter to the normal functioning, but to ensure safety in case of a short, it should DEFINITELY be corrected.
You probably have a bad magnetron (again) and possibly a bad high voltage rectifier diode too.
GE had a campaign (but not a recall, mind you!) covering several models.
Details are in their bulletin at http://126.96.36.199/mwd/ge_mw_mag_kit_bulletin.pdf
The parts kit (that GE used to pay for) is part # WB27X10489 and is shown in the photo below.
