Alignment And Adjustments; High Voltage Transformer - Samsung CE1279KSE Service Manual

5. Alignment and Adjustments

1. High voltage is present at the high voltage terminals during any cook cycle.
2. Do not attempt to measurement the high voltage.
3. Before touching any oven components or wiring, always unplug the oven and discharge the high voltage capacitor.

5-1 High Voltage Transformer

1. Remove connectors from the transformer terminals
and check continuity.
2. Normal resistance readings are as follows:
MODEL
Secondary
Filament
Primary
(Room temperature = 20ûC)
5-2 Low Voltage Transformer
1. The low voltage transformer is located on the
base plate.
2. Remove the low voltage transformer from the
base plate and check continuity.
3. Normal resistor readings a shown in the table.
5-3 Magnetron
1. Continuity checks indicate only an open filament
or a shorted magnetron. To diagnose an open
filament or shorted magnetron, do the following:
2. Isolate the magnetron from the circuit by
disconnecting its leads.
3. A continuity check across the magnetron filament
terminals should indicate one ohm or less.
4. A continuity check between each filament terminal
and the magnetron case should read open.
