E3 Overheating — restricted exhaust vent (dryer)
What this code means
The dryer has detected dangerously high temperatures, almost always from an airflow restriction, and this is treated as a high-urgency safety code. Note: the exact on-screen code varies by GE dryer platform — some models show "E3", others show "AF" (Check Vent) or a numeric fault code instead. If your display shows something different but you smell burning or the vent feels hot, treat it the same way.
Most likely causes
- Severely clogged lint screen or exhaust duct
- Crushed or kinked vent hose
- Blocked exterior vent cap
What to try first
Do not keep running the dryer with this code. Clean the lint screen and inspect the full exhaust run, including the exterior flap, before using it again.
Safety first: stop using the appliance and shut off its gas or power until it has been inspected — this fault category is associated with fire or gas risk.
