Enter the code shown on your dryer display

Is it safe to keep using it?

Depends on code severity. Low/Medium codes often allow continued use, High severity requires immediate stop.

Can error codes be reset?

Some codes clear after power cycle. Persistent codes indicate underlying issues needing repair.

When should I stop using it?

Stop immediately for water leak codes, burning smell, or any High severity error.

Low Medium High
Code Meaning Severity Common Symptom
AF Restricted Airflow / Vent Blockage High The control board halts or significantly lengthens the drying cycle and flashes AF on the display — or shows "Check Vent" on models with text displays — to alert the user that exhaust airflow has dropped below the minimum threshold for safe operation. View F01 Main Electronic Control Board Failure Medium The control board locks out all cycle starts when F01 is active. Selecting a cycle and pressing Start does nothing, or the dryer briefly tumbles then stops and redisplays F01 within seconds. View F06 Drive Motor Tachometer Error High The motor attempts to start when the cycle begins, but because the control board receives no valid tachometer feedback within the first few seconds of operation, it shuts the motor off and displays F06. View F22 Exhaust Thermistor (Outlet Temperature Sensor) Fault High The control board halts heating — and sometimes the entire cycle — when F22 is active because it cannot verify exhaust temperature is within safe limits. The drum may continue to tumble with no heat, or the dryer may abort the cycle entirely. View F26 Door Switch Fault Medium The control board sees an open door switch circuit and refuses to start the motor or heater. Pressing Start results in F26 displaying without any drum movement. View F28 Moisture Sensor Strip Fault Medium If the moisture sensor circuit reads as a short (very low resistance), the board interprets it as the load being bone-dry before the cycle has run long enough, stopping the dryer prematurely and leaving clothes damp. View F30 Restricted Airflow Detected — Blocked Lint Screen or Duct High The control board detects inadequate exhaust airflow through thermistor temperature differential monitoring and displays F30. On some Kenmore models the code appears at the end of a cycle; on others it halts the cycle mid-run. View F70 No Communication Between Main and User Interface Boards Medium With no communication link to the UI board, the main board cannot receive cycle selections or Start commands — the dryer is completely locked out from operation and no cycle can be started. View L2 Low or No L2 Voltage on Heater Circuit (Electric Dryers) High Because the motor and control board run on L1 alone, the dryer starts, the drum tumbles, and the timer advances — but without L2, the 240 V heating element never reaches operating temperature and the exhaust air stays at room temperature. View PF Power Failure — Cycle Interrupted Low The dryer displays PF immediately upon power restoration and does not resume the interrupted cycle automatically — it waits for user input before restarting.
