A fan that runs may still remove moisture poorly if its intake is dirty or ventilation is inadequate. These steps separate safe observations from electrical maintenance that needs a qualified professional.

1. Switch on the bathroom fan while showering or bathing. Check the building's ventilation instructions and whether the exhaust goes outdoors. Do not alter shared apartment ventilation systems.
2. Continue running it for about 15 minutes afterward. ENERGY STAR offers this as general moisture-control advice; the actual time needed varies with the room and moisture load.
3. Look for lingering condensation on mirrors and tiles. Wipe wet surfaces and spread mats or curtains to dry. Persistent dampness calls for a check of exhaust performance, not just longer running.
4. Visually inspect the outside grille for dust. Clean only accessible exterior surfaces in the way the maker permits. Turn off power before cleaning and do not climb on unstable furniture.
5. If removing the grille is necessary, consult the product manual and proper power-isolation method first. If you cannot safely isolate electricity or reach the unit, use a qualified professional. Never spray liquid onto electrical components.
6. Reassemble only when fully dry and as directed, then listen for normal operation. Unusual noise, burning smells, persistent condensation, leakage or faulty ducting require professional inspection.
