Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the unit. A non-running fan can cause the compressor to overheat; do not continue to operate the unit in this condition.
- Step 1 – Check fan settings: Ensure the fan speed is not set to an off or low mode that appears stopped (some models always run the fan when dehumidifying).
- Step 2 – Inspect for obstructions: Look through the grille for objects blocking the fan or blower wheel.
- Step 3 – Spin test (advanced): With the cover removed and power disconnected, try spinning the blower wheel by hand. If it is stiff or seized, the motor bearings may have failed.
- Step 4 – Electrical test: Use a multimeter to check for power at the fan motor leads when the unit is calling for fan operation. If power is present but the motor does not run, replace the fan motor.
- Step 5 – Replace fan motor: Install a Danby-compatible fan motor, transferring the blower wheel and ensuring proper alignment.
When to call a technician: Fan motor replacement involves electrical work and partial disassembly; professional service is recommended if you are not experienced.
