Disconnect the low voltage transformer
connector from the oven control board.
3.
Set the ohmmeter to the R x 1 scale.
4.
Touch the ohmmeter leads to the indi-
cated slots of the low voltage transformer
connector. The meter should indicate as
follows:
1st Secondary—Pins 1 & 2 = Less than 1
Ω
.
2nd Secondary—Pins 3 & 4 = Less than 1
Ω
.
3rd Secondary—Pins 5 & 6 = Less than 1
Ω
.
Primary—Pins 8 & 10 = Approximately 5
Ω

& LIGHT POWER SUPPLY
LOW VOLTAGE TRANSFORMER
Refer to page 2-5 for the procedure for servic-
ing the light power supply.
1.
Disconnect the electrical power to the
microwave oven.
2.
Disconnect one of the wires from each of
the light power supply LOAD and LINE
terminals.
3.
Set the ohmmeter to the R x 1 scale.
4.
Touch the ohmmeter leads to the LOAD
terminals. The meter should indicate less
than 1
Ω
.
5.
Touch the ohmmeter leads to the LINE
terminals. The meter should indicate ap-
proximately 46
Ω
.
