  Outlet Thermistor (NTC1)

The outlet thermistor is located on the back of the 

blower housing.

The thermistor measures drum outgoing air 

temperature and responds to temperature 

changes.

The control board makes heating decisions based 

on this information.

Outlet Thermistor Removal

1.  Remove the front panel (see 

Front Panel

 

in the 

Dryer Components

 section of this 

service guide).  Disconnect the wire harness 

connector.

2.  Remove the two Phillips-head screws 

securing the thermistor to the blower housing.

The thermistor has a negative temperature 

coefficient (as temperature increases, resistance 

decreases).

Resistance can be measured at the thermistor 

wire harness.  Make sure to disconnect the wire 

harness to isolate the thermistor before taking 

readings.

Operation of the thermistor can be checked by 

using the service mode test t07 (see 

Service 

Mode Test

 in the 

Diagnostics

 section of this 

service guide).

Specific faults associated with the outlet 

thermistor can initiate Fault Code E4 (see 

Fault Codes

 in the 

Diagnostics and Service 

Information

  section of this service guide).
