Recently replaced thermistor (2 mos. ago) after getting check filter and long drying times, with clothes remaining damp after several sensor dry cycles. Worked like new for 2 mos. now, same symptoms. This time I replaced thermistor. No change. Unit now self-diagnoses as open thermistor (LE01). I checked resistance on both thermistors. Each is 10 ohm. The sensor circuit tests 14kohm at 60-68 F, so that's in spec. Service manual says check controller connection. I believe it's good, so not wiring (assuming). Manual says replace controller. Does this seem correct? Need advice before replacing controller.
ANSWER Hello George,
Yes this would be correct. As long and wiring and the thermistors are checking out ok then it would be the controller that is at fault. You can do a continuity check on the wiring from the sensor to the control board which will tell you whether there is a wiring issue. If you have an open line this would cause the error.
