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.
