How to Fix / Troubleshooting

Safety first: Unplug the dryer. Ground faults can cause electric shock and must be treated seriously.

Visual inspection:
- Remove the rear panel to access the heater assembly.
- Look for signs of arcing, burn marks, or melted insulation around the heater.
Check for moisture: Ensure the heater housing is dry and free of condensation or water leaks.
Test heater to ground (if equipped):
- With a multimeter on resistance, measure between each heater terminal and the metal chassis.
- Any low resistance reading indicates a ground fault; the heater must be replaced.
Inspect wiring: Replace any wires with damaged insulation or burnt connectors.
After replacement: Reassemble, restore power, and test a short warm cycle to confirm the fault is cleared.

Warning: Do not continue using the dryer if F15 persists; contact a qualified technician.

Dryer displays F15 and may not heat or may stop shortly after starting.
