Component Testing
Illustration Component Test Procedure Results
Power supply Disconnect power from cooktop and
verify circuit breakers/fuses are not
tripped. Check fuse rating. Check
terminals at terminal block for
tightness. Verify cooktop service wires
are properly connected, and are in
good condition. Check for proper
voltage with a voltmeter .........................
Refer to schematic diagram for correct
voltage measurements
Internal wiring Disconnect power from cooktop, place
one ohmmeter lead at the terminal
block, the other lead at the line terminal
of the malfunctioning part. Use the
appropriate wiring diagram to repeat this
procedure from the output of the control
to the component, until each section is
checked. A visual check of the wiring
will often determine the fault location .....
