What this code means
The dryer detected a heating temperature outside its expected range. A restricted lint screen or exhaust duct is a leading cause and presents a fire risk.
Most likely causes
- A clogged lint screen, transition duct or house vent
- A crushed or excessively long exhaust duct
- A thermistor giving incorrect feedback
- A heater relay, gas-valve or control fault causing abnormal heat
Safe checks for the owner
- Stop the dryer and allow it to cool.
- Clean the lint screen and inspect the full exhaust path to the exterior.
- Do not use the dryer again if the cabinet is extremely hot, there is a burning smell or the vent has weak airflow.
Estimated U.S. repair cost
$190–$390, depending on model, access, parts availability and local labor.
