TROUBLESHOOTING Before Calling for Service The dryer is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the dryer does not function properly or does not function at all, check the following before you call for service. Error Messages Problem tE1 through tE7 Possible Cause & Solution Temperature sensor failure. • Turn off the appliance and call for service. Power cord is connected incorrectly.
TROUBLESHOOTING 51 Problem Possible Cause & Solution House fuse is blown, circuit breaker has tripped, or power outage has occurred. The appliance does not heat. House fuse is blown, circuit breaker has tripped, or power outage has occurred. • Reset circuit breaker or replace fuse. Do not increase fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician. • Reset circuit breaker or replace fuse. Do not increase fuse capacity.
TROUBLESHOOTING Problem Drying time is not consistent. Possible Cause & Solution Heat settings, load size, or dampness of clothing is not consistent. • The drying time for a load will vary depending on the size of the load, the type of fabrics, the wetness of the clothes and the condition of the lint filter. Even an unbalanced load in the washer can cause poor spinning, resulting in wetter clothes which will take longer to dry. Performance Problem Clothes are wrinkled.
TROUBLESHOOTING 53 Problem Excess static in clothes after drying. Possible Cause & Solution Fabric softener is not used or is used incorrectly. Clothes dried too long (overdried). • Overdrying a load of laundry can cause a buildup of static electricity. Adjust settings and use a shorter drying time, or use Manual Dry cycles. Select a lower dry level setting on Sensor Dry cycles, if necessary. Drying synthetics, permanent press, or synthetic blends.
TROUBLESHOOTING Problem Possible Cause & Solution Drum does not turn during Steam Cycle. This is normal. Cannot see steam vapor at the beginning of cycle. This is normal. Odors remain in clothing after Steam Steam FreshTM did not remove odor completely. FreshTM. • The drum is turned off so that the steam vapor remains in the drum.
