What F15 Means
F15 means the dryer's overheating protection has tripped — internal temperature climbed beyond the safe operating range and the machine shut the heating circuit down as a precaution.
Common Causes of F15
- Severely restricted exhaust airflow
- Failed thermal cutoff or NTC sensor
- Heating element short circuit
🔧 One Safe Check You Can Try
Stop the cycle, let the dryer cool for at least 30 minutes, and check the exhaust vent and lint screen for blockage before running it again — do not repeatedly restart a dryer that has overheated.
⚠ Why You Shouldn't Go Further Than That
- A genuine overheating event should have its root cause confirmed before the dryer runs again, since repeated overheating is a fire-risk pattern, not a one-off glitch to ignore.
- Distinguishing restricted airflow from a failed thermal cutoff or a heating element short requires testing components electrically, not just clearing the vent.
- A heating element short circuit involves live high-current wiring, which is technician work to diagnose safely.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
