Capacitor And Diode; Magnetron Tco; Hood Tco - GE SCA1000 Technical Service Manual

Capacitor and Diode

WARNING: Always be certain the capacitor is
discharged before servicing. Mechanically
discharge by placing an insulated handle
screwdriver between the diode connection of the
capacitor and the oven chassis ground.
Note: The high voltage capacitor has an internal
discharge resistor that automatically discharges
the capacitor when the oven turns OFF. Under
normal operation, the capacitor should fully
discharge within 30 seconds.
• The case may be removed to provide greater
access to the capacitor and diode.
1. Remove the grille and vent cover (see
procedures).
2. Remove the sub PCB (see procedure).
3. Disconnect the wire leads from the capacitor.
