H.V. Inverter warning
WARNING FOR INVERTER POWER SUPPLY (U) GROUNDING
Check the high voltage inverter power supply circuit grounding.
The high voltage inverter power supply circuit board must have a
proper chassis ground, the inverter grounding bracket must be
connected to the chassis. If the inverter board is not grounded it
will expose the user to very high voltages and cause extreme
DANGER! Be sure that the inverter circuit is properly grounded via
the inverter earth bracket.
Grounding of the inverter circuit board
WARNING! DISCHARGE THE HIGH VOLATGE CAPACITORS
For about 30 seconds after the oven is turned off, an electric charge
remains in the high voltage capacitors in the inverter power supply
circuit board.
When replacing or checking parts, remove the power plug from the
outlet and short the inverter output terminal of the magnetron
filament terminals to the chassis ground with an insulated handle
screwdriver to discharge. Please be sure to touch the chassis
ground side first and then short to the output terminals.
