Power Transformer Removal
Removal
1. Disconnect the oven power supply cord and remove
outer case.
2. Open the oven door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect wire leads (primary and high voltage)
from power transformer and the filament leads from
the magnetron and capacitor terminals.
5. Remove four (4) screws holding transformer to
bottom
plate.
6. Remove transformer from bottom plate.
Re-Install
1. Rest transformer on the bottom plate with its primary
terminals toward the oven face plate.
2. Secure transformer with four screws to bottom plate.
3. Re-connect wire leads (primary and high voltage) to
power transformer and filament leads of transformer
to magnetron and high voltage capacitor. Refer to
Wiring Diagram.
4. Re-install outer case and check that oven is
operating
properly.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
When replacing outer case, the two (2) special Torx
