COMPONENT TESTING
Many of the range component circuits can be tested at the EOC wiring harness with an ohm meter.
By following the wiring diagram and schematic diagram it is possible to perform continuity tests on the
bake and broil ignitor circuits, lock motor windings, oven door switch and other component circuits.
When testing for continuity the power supply must be turned off or disconnected and the wire
harness connector(s) for the circuit or component being tested must be unplugged from the
EOC. You must also ensure that the test probes of the meter are small enough to make contact with
the wire terminal inside the harness plug.
By testing from the EOC harness plug the component part as well as the wire harness are tested at
the same time. If the component circuit test fails at the EOC harness then a test of the component
part itself is needed to verify that the component is faulty.
The wiring diagram below from model GLGF386D** shows all of the component circuits controlled
by the EOC. By following the Component Test Point Matrix found on the next page most of the
component circuits can be tested from the P5 harness connector.
By following the wiring diagram and schematic to determine which wires connect to the various
components this technique can be applied to any model. The accompanying GAS RANGE
COMPONENT RESISTANCE CHART provides the approximate resistance values of various
components.
