TURNTABLE MOTOR
Refer to page 4-25 for the procedure for ac-
cessing the turntable motor.
1. Unplug microwave oven or disconnect
power.
2. Disconnect one of the wires from the
turntable motor terminals.
3. Set the ohmmeter to the R x 10K scale.
4. Touch the ohmmeter test leads to the
motor terminals. The meter should indi-
cate between 2700 and 3800
Ω.
HIGH-VOLTAGE TRANSFORMER
Refer to page 4-24 for the procedure for ac-
cessing the high-voltage (H.V.) transformer.
1. Unplug microwave oven or disconnect
power.
2. Disconnect the wires from the H.V. trans-
former terminals.
3. Disconnect the H.V. transformer wires from
the magnetron and the H.V. capacitor.
4. Set the ohmmeter to the R x 1 scale.
5. Touch the ohmmeter test leads to the fol-
lowing H.V. transformer locations:
Filament wire (org/red) to ground =
•
Infinite.
Primary terminals (red & white) wires =
•
less than 1 Ω.
Secondary (red & white) wires = 60 Ω
•
(approximately).

Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
