Kenmore Dryer Error Code d80

The d80 code means the dryer's exhaust system is approximately 80% to 95% blocked, which the dryer detects through reduced airflow performance. The restriction can be anywhere in the exhaust path, from the duct work inside the wall to the exterior vent cap. The dryer displays this alert to prevent overheating and potential fire hazards. Clearing the blockage in the exhaust system is required to resolve the code.

No, you should not continue running the dryer while the d80 code is active. A duct that is 80% to 95% blocked traps heat inside the dryer, which creates a serious risk of overheating and can ignite accumulated lint, potentially causing a fire. Stop using the dryer until the exhaust restriction has been found and cleared.

If the fix is a simple duct cleaning you can do yourself, the cost is minimal, typically just the price of a dryer vent cleaning brush kit, which usually runs in the range of $15 to $40. If a professional duct cleaning service is needed, expect to pay roughly $80 to $175 depending on the length and complexity of the duct run. If the flexible transition hose needs replacement, those parts generally cost between $10 and $30. More complex duct reconfiguration work by a contractor can run higher depending on the scope of the job.

Start by going outside and checking the dryer vent cap while the dryer is running to see if air is flowing out. If airflow is weak or absent, disconnect the transition hose at the back of the dryer and clean the entire duct run from the outside cap inward using a dryer vent brush kit. Also inspect the transition hose itself for kinks, crushing, or internal lint buildup and replace it if damaged. Once the exhaust path is fully clear, the error condition should resolve on its own.

Resetting the dryer will not permanently clear the d80 code if the underlying exhaust restriction is still present. The code will return once the dryer runs again and detects the same restricted airflow. The only way to clear the code for good is to locate and remove the blockage from the exhaust system so that proper airflow is restored.
