Before measuring resistance, be sure to turn power off, and do voltage discharge.
(When discharging, contact the metal plug of power cord with ground line.)
Degree of dryness does not match with dry Level.
Turn the dryer’s power off, then measure resistance.
Take NA6 Connector from
the Controller.
Metal or Wire
Damping cloth
Short with metal to the 6 pin connector’s
Pin (Orange Wire) and Pin (Blue Wire) to controller.
When measuring resistance in electric load,
is resistance below 1
Ω
?
• Check electro Load
and harness
connector
• Check harness-
linking connector.
• Replace control
and check.
When contacting cloth to electro load:
1.Is the measurement within the range of Table 2
during Diagnostic Test?
2.Is the measurement within the range of Table 2
when measuring the voltage in the NA6 connector’s
Pin
(Orange wire) and Pin (Blue wire)?
