Halogen Light Transformer(s)

One transformer (120V-12V 40VA) is utilized per cavity. Triac
switches 120 VAC to the transformer. There are 4 terminals on the
new transformer, as shown in Figure 17.
The resistance between the primary terminals should measure ~12.8
ohms and the resistance between the secondary terminals should
measure ~0.32 ohms.

Convection Fan Motor

The convection fan motor is 120V 29W. To test the motor, check for
120V across X105 / Pin 2 (upper/single) or X205 / Pin 1 (PODC) and
chassis ground or neutral.
The motor is accessible from the rear, after removing the rear outer
sheet metal panel.
1. Disconnect the 2 wires from the motor terminals.
2. Remove 3 T20 screws from the arms of the motor assembly.
3. Use a tap and a hammer to dislodge the assembly from the
clips that secure it to the rear of the unit. (Position tap on the
arm secured by the rightmost clip.)
