WARNING: To prevent electrical shock, use
extreme caution when diagnosing oven with
outer covers removed and power on. The
high voltage circuit of the magnetron power
area (HVT, capacitor, diode, magnetron) is
4400V potential with respect to ground. Wait
at least 5 minutes after disconnecting
power before servicing the magnetron
power area.
WARNING: Heat sinks on main power
board are electrically live. Take special
precautions when troubleshooting the main
power board with power on. If the main
power board has failed, the board capacitor
can hold a voltage charge on the heat sinks.
Wait at least 5 minutes after disconnecting
power before servicing the main power
board.
