Re-install
1. Insert tube into filament lead (longer one) of power
transformer.
2. Install the terminal insulator to receptacle of filament
lead (longer one) of power transformer.
3. Rest transformer on the bottom plate right with its primary
terminals toward the oven face plate.
1. Open covers of the terminal insulator by using small flat
type screw driver.
2. Remove the receptacle from the terminal insulator.
3. Now, the terminal insulator is free.
