GE Dryer E2 Error — Exhaust Sensor Out of Range

What Does This Error Mean?

E2 means the exhaust thermistor is reading a temperature outside the normal range — usually because the vent is blocked and exhaust temperatures have spiked, or the sensor itself has failed.

Affected Models

GE Electric Dryer
GE Gas Dryer
GE GTD Series
GE Profile Dryer

Common Causes

Clogged exhaust vent (most common cause)
Failed exhaust thermistor reading too high or too low
Lint buildup around the sensor body
Kinked or crushed exhaust duct restricting airflow

How to Fix It

Clean the exhaust vent thoroughly.

Disconnect the duct from the back of the dryer and the wall outlet. Use a dryer vent brush to remove all lint along the full duct run. Check the outside vent cap is not blocked.
Remove lint from inside the cabinet.

Unplug the dryer and remove the back panel. Vacuum any lint accumulation around the blower housing and thermistor body.
Test the exhaust thermistor.

With the dryer unplugged, test thermistor resistance with a multimeter. If it reads open or zero, replace it. If the vent was the problem and the sensor tests within spec, cleaning alone should fix E2.

When to Call a Professional

If cleaning the vent clears E2 but it returns within a few cycles, the thermistor has been damaged by repeated overheating and should be replaced.
