Test 8 Semi Conductor Caution Before measuring resistance, be sure to turn Power off, and do voltage discharge. (When discharging, contact the metal plug of Power cord with earth line.) Trouble Symptom Degree of Resistance is not in 300°æ30 Ω Measurement Condition Turn the Dryer's Power Off, then measure resistance. Take 6pin Connector from the Controller. When measuring resistance Is resistance 300 20 Ω? NO YES • Check Semiconductor and Harness Connector • Check Harness linking connector When measuring resistance in Semi-Conductor Is resistance 300 20 Ω? 1. Is the measurement within the range of 300 20 Ω between Red-White? 2. Is the measurement within the range of R BW 300 20 Ω between Black-White? NO • Replace Control and Check. YES Normal Condition 30
