40% ~ 20%
10% ~ dried clothes
egree of dryness does not match with dry level.
Turn the dryerÕs power off, then measure resistance.
Short with metal to the 6 pin connectorÕs pin
(Blue Wire) and
Pin (Orange Wire) to controller.
When measuring resistance in electrode load,
is resistance below 1½?
When contacting cloth to electrode:
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 6 pin connectorÕs
Pin (BLUE wire) and Pin (ORANGE wire)?
