Test 2
Thermistor Test --- Measure with Power Off
Before measuring resistance, be sure to turn the power off and discharge voltage.
(When discharging, contact the metal plug of power cord with the ground.)
During diagnostic test, tE1 and tE2, an error occurs.
During operation, the heater does not turn off.
Difference between actual and sensed temperature is significant.
After turning power off, measure the resistance.
Measure the resistance between the
NA8-③(BL) and NA8-②(YL) Does the
resistance measured match the temperature
of the thermistor in the chart? (Use room
termistor is warm from running the dryer.)
• Check if control
and the 8 Pin
connector are
properly
connected.
• Replace
controller
• Replace
thermistor.
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.
