GE Dryer Error Code tE4

The tE4 code means the dryer's control board has detected a fault in the outlet thermistor circuit. Specifically, the thermistor's voltage signal has gone above 4.8V or below 0.2V for more than 5 seconds, indicating an open circuit, a short, or a wiring problem. The outlet thermistor monitors exhaust air temperature, and the dryer cannot operate safely without a valid reading from it.

Start by locating the outlet thermistor connector and checking that it is fully seated and free of corrosion. Then inspect the wiring harness between the thermistor and the control board for any breaks or damage. If the connector and wiring look good, test the thermistor itself for correct resistance. If the sensor has failed, it will need to be replaced.

If the fix is simply reseating a loose connector, there may be no parts cost at all, though a service call from a technician would typically run between $75 and $150. If the thermistor itself needs to be replaced, parts generally cost in the range of $15 to $50, with total repair costs including labor falling between $100 and $250 depending on your location and service provider. Wiring harness repairs can vary more widely depending on the extent of the damage.

A power reset may temporarily clear the display, but if the underlying wiring or sensor problem is still present, the tE4 code will return once the dryer attempts to operate again. A reset is useful for confirming whether the fault is intermittent, such as a loose connector, but it is not a fix. The thermistor circuit needs to be inspected and repaired for the code to stay cleared.

It is not recommended to continue running the dryer while tE4 is active. The outlet thermistor is part of the dryer's temperature monitoring system, and without a valid reading, the dryer cannot properly regulate exhaust heat. Running the dryer in this condition could create an overheating risk. The fault should be diagnosed and repaired before resuming normal use.
