ARNING
!
Before measuring resistance, be sure to turn power off, and do voltage discharge. (When discharging,
contact the metal plug of power cord with the ground.)
Failure to follow these instructions can result in death or electric shock.

uring operation, Heater would not turn off or remains on.
ifference between actual and sensed temperature is significant.
After turning power off, measure the resistance.

Check if resistance is in the range of Table 1
when measuring resistance between
terminals after separating harness
from thermistor assembly connector.
Check harness-linking connector.
