NEGATIVE TEMPERATURE
COEFFICIENT (NTC) SENSOR
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.
WARNING
Refer to page 4-6 for the procedure for ac-
cessing the negative temperature coefficient
(NTC) sensor.
NOTE: Each of the inductors uses a negative
temperature coefficient (NTC) sensor for moni-
toring the operating temperature. The sensors
are interchangeable. Use conductive grease
when replacing a sensor to aid in thermal con-
duction.
1. Unplug cooktop or disconnect power.
2. Disconnect the NTC wires from the elec
-
tronic board.
3. Set the ohmmeter to the R x 1 scale.
4. Touch one of the ohmmeter test leads to
the pins of the NTC connector. The meter
should indicate as shown in the charts.
