K. REMOVING THE TURNTABLE MOTOR

(1) Remove the turntable.
(2) Remove the turntable shaft VERY CAREFULLY

with a slotted screwdriver. (Figure 20)

(3) Remove the base plate by removing 7 screws

securing it to the oven cavity. (Figure 21)

(4) Disconnect the leadwire from the turntable motor

terminals.

(5) Remove the 2 screws securing the turntable motor

to the oven cavity ASS'Y. (Figure 22)

NOTES:
