Modern dryers display error codes to help diagnose problems quickly. Understanding these codes can help you fix common issues yourself and avoid expensive service calls. This guide covers error codes for all major dryer brands.

⚠️ Important Safety Note: Some dryer errors indicate fire hazards (especially airflow restrictions). Always address dryer errors promptly and clean your dryer vent system regularly.

LG d80 Restricted Airflow Error Moderate Fix d80 →
Samsung dC Door Open Error Easy-Moderate Fix dC →
Whirlpool F01 Primary Control Failure Moderate-Hard Fix F01 →

Most Critical Dryer Errors (Fire Safety)

🔥 Address These Immediately:

  • LG d80/d90/d95 – Airflow restriction (lint buildup = fire hazard)
  • Samsung dC – Door not closing (can cause overheating if bypassed)
  • High temperature errors – Overheating indicates vent blockage

Why these matter: Dryer fires cause ~15,000 home fires annually in the US. Most are caused by lint buildup restricting airflow. Never ignore airflow errors.

Common Dryer Problems Across All Brands

Door/Lint Issues:

  • Door won’t close or latch (dC, F5 errors)
  • Lint buildup around door seal
  • Door switch failure

Airflow/Vent Issues:

  • Restricted exhaust (d80, d90 errors)
  • Clogged vent duct
  • Blocked exterior vent hood
  • Too many elbows in vent run

Electrical Issues:

  • Control board failure (F01 errors)
  • Power supply problems
  • Thermal fuse blown

Quick Dryer Troubleshooting

Start Here:

  1. Clean lint filter: After EVERY load (prevents 90% of dryer fires)
  2. Check vent system: Clean annually minimum, more if heavy use
  3. Verify door closes: Nothing blocking seal or latch
  4. Reset dryer: Unplug for 60 seconds, plug back in
  5. Test empty cycle: Rules out overload issues

Dryer Vent Safety (CRITICAL)

Fire Prevention Best Practices:

  • Clean lint filter after every load – Non-negotiable
  • Inspect vent duct annually – Look for lint buildup, damage
  • Clean entire vent system yearly – From dryer to exterior
  • Use rigid metal duct – Never use plastic or foil accordion
  • Minimize vent length – Under 25 feet ideal, 35 feet maximum
  • Limit elbows – Each 90° turn reduces airflow significantly
  • Check exterior vent – Remove lint, ensure flap opens freely
  • Never vent indoors – Always vent to exterior of building

Warning signs your vent needs cleaning:

  • Clothes take 2+ cycles to dry
  • Dryer exterior is very hot to touch
  • Burning smell when running
  • Laundry room feels humid and hot
  • Lint visible around dryer door
  • d80/d90 error appears (LG dryers)

Consider repair if:

  • Dryer is less than 7 years old
  • Single component failure
  • Repair cost under $200
  • Otherwise functioning well
