Why Your Dryer Displays an Error Code
When your dryer displays an error code on the control panel, it’s not just a glitch. These warnings are built-in safety alerts that tell you the vent system is clogged, the exhaust system is blocked, or the machine is overheating. In many cases, lint buildup or improper venting is the root cause.
In Middlesex and Essex County, with older homes and long ductwork, airflow restrictions are common. If the error persists after cleaning the lint trap, the machine may already be under strain. Dryer Vent Wizard of Middlesex-Essex provides professional vent cleaning to restore safe airflow and ensure your dryer is working properly.
Common Dryer Error Codes
Each brand uses different alerts, but most dryer error codes point to airflow problems or dryer’s internal components struggling with restricted airflow.
LG Dryer Codes
- d75 – 75% airflow restricted
- d80 – 80% blocked
- d90 – 90% blocked
- d95 – 95% blocked
- FO – Lint trap missing
- HS – Humidity sensor detected a malfunction
- CL – Child lock active
If your lg dryer flashes d80 through d95, it may require service quickly. Don’t wait until the error continues, contact Dryer Vent Wizard of Middlesex-Essex to fix the blockage.
Samsung Dryer Codes
Blockage & Overheating
- Clg / Cg – Vent clogged
- C80 – 80% blockage
- C90 – 90% blockage
- HC / hE / HC4 – Heat detected from blocked vent
Sensor Issues
- tS / tC – Control sensor errors
- dE – Dryer door not closed
- CL – Child lock engaged
When a Samsung dryer shows these alerts, don’t keep running the machine. If the error code persists, it signals your vent system needs further assistance.
Whirlpool, Maytag, and Kenmore
- AF – Restricted airflow
- F4 E3 – Equivalent to AF
- F30 (Kenmore) – Blockage from fabric softener residue and lint buildup
If the error continues after you unplug and reset the machine, it’s time to request service.
Amana
- AF / “Check Vent” – Restricted vent system
GE, Electrolux, and Frigidaire
- Clean filter – Reminder that airflow may be blocked
- EF1 – Ventilation blockage
- E22 / E64 – Heater faults detected
Bosch
- E01 / E02 / E03 – Blocked fluff filter or duct
Speed Queen
- AF / EAF2 – Airflow restricted by clogged lint trap
Across all brands, these codes share the same message: airflow is blocked, and the dryer may require service if the problem continues.
Why Airflow Issues Need Immediate Attention
When airflow is reduced, the dryer displays alerts because the machine cannot vent heat and moisture effectively. This leads to:
- Longer drying cycles and wasted energy
- Overheating can damage the dryer’s internal components
- Fire risk from trapped lint buildup
Dryer Vent Wizard of Middlesex-Essex can verify airflow, check the power cord and connection, and provide vent cleaning before the error code escalates into costly repair.
Fabric Softener Residue and Lint Buildup
In addition to lint, fabric softener residue coats the lint trap and clogs airflow. Over time, this causes dryer error codes to appear.
Signs of buildup:
- Sticky lint filter
- Clothes are damp after a drying cycle
- Burnt smell from the machine
Prevention:
- Wash the lint trap monthly
- Use less fabric softener
- Book annual vent cleaning for your electric dryer
A Few Troubleshooting Steps Before Calling
Homeowners can attempt a few troubleshooting steps before they request service:
- Unplug the power cord for 5–10 minutes to reset the system
- Clean the lint trap and housing
- Inspect the drain hose and water supply if your combo unit shows other errors
- Ensure the outlet has the correct voltage
- Restart the machine
If the error persists, that means the ductwork or vent system needs professional cleaning.
Other Errors and Warning Signs
Even without a flashing dryer error code, you may notice:
- The machine is running hot
- Multiple cycles needed for a single load
- Burning smell from excess heat
- Lint and debris around the exhaust system
These are also signs you should contact Dryer Vent Wizard of Middlesex-Essex for further assistance.
Cleaning Frequency for Middlesex-Essex Homes
Homeowners in Middlesex and Essex County should plan vent cleaning as follows:
- Annually – Standard homes
- Every 3–4 months – Families with pets, long ducts, or heavy laundry loads
- Every 3–5 years – Light-use households
The maximum vent length is 25 feet, minus 5 feet for each 90° bend. Longer systems increase the risk of error alerts.
Local Hazards for Middlesex-Essex Dryers
Environmental factors that trigger dryer error codes include:
- Leaves in the fall clog exterior vents
- Snow is blocking the exhaust vent in winter
- Spring pollen is combining with lint buildup
- Rodents nesting in the ducts
These hazards often lead to improper venting, which can trigger an error code even if the dryer seems to be working properly.
