Dryer Error Codes by Brand: What They Mean
Dryer error codes point to airflow restriction, heating faults, or sensor problems. Airflow codes are the most common — D80/D90/D95 on LG, AF on Whirlpool, Clg on Samsung — and nearly always mean a clogged vent rather than a broken part. Find your brand to decode yours.
What to Check First
- 1
Note the exact code from the display.
- 2
Airflow codes (LG D80/D90, Whirlpool AF, Samsung Clg) mean clean the vent run — start there.
- 3
Heating codes usually involve the thermal fuse, element, or thermistor.
- 4
Look up your specific brand's code for the exact cause and fix.
- 5
A blown thermal fuse won't reset — replace it and fix the vent restriction that blew it.

Miele Dryer Frequently Asked Questions
What is the most common dryer error code? +
Airflow/vent-restriction codes are by far the most common: LG's D80/D90/D95, Whirlpool's AF, and Samsung's Clg. They measure duct blockage and almost always mean the vent needs cleaning, not a part replaced.
