If your kitchen or bathroom feels stuffy, the extractor fan is probably clogged. A blocked fan not only smells bad, it can overheat and break. The good news? Most blockages are easy to clear with a few tools you already have at home.
Why Your Fan Gets Blocked
Grease, dust, and hair are the usual suspects. In the kitchen, cooking splatters coat the fan blades and the vent pipe. In a bathroom, hair and soap scum build up on the fan and the duct. Over time the buildup reduces airflow, makes the motor work harder, and eventually stops the fan from spinning.
Another common cause is a loose or broken filter. Many fans have removable metal or charcoal filters that catch debris. If the filter is full, air can’t pass through, and the fan sounds like it’s trying but can’t turn.
Step‑by‑Step Unblocking Guide
1. Turn off power. Safety first – switch off the circuit breaker or unplug the fan. You don’t want a surprised shock while you’re pulling things apart.
2. Remove the grille. Most extractor fans have a snap‑on or screw‑down cover. Use a screwdriver if needed, then set the grille aside.
3. Check the filter. Take out the filter and give it a good shake. If it’s metal, rinse it under warm water and scrub with a soft brush. For charcoal filters, replace them – they can’t be fully cleaned.
4. Clean the blades. Use a damp cloth or a soft brush to wipe away grease and dust from the fan blades. For stubborn grease, mix a little dish soap with warm water, dip the cloth, and wipe carefully.
5. Inspect the duct. Look down the vent pipe from the fan side. If you see a lot of buildup, detach the duct (usually a clamp or slip‑fit) and pull it away from the wall. Run a long brush or a vacuum hose through the pipe to dislodge debris. A flexible dryer‑sheet tube works well for tight spots.
6. Reassemble and test. Put the duct back, screw the grille on, and restore power. Turn the fan on – you should hear a smoother spin and feel better airflow.
If the fan still struggles, the motor might be worn out. In that case, it’s smarter to call a professional rather than keep forcing it. A motor replacement costs less than a full kitchen remodel, and a qualified technician can do it safely.
Regular maintenance keeps the fan happy. Wipe the grille and filter every month, and give the blades a quick clean every few weeks if you cook a lot. This habit prevents big blockages and extends the life of the fan.
Got a stubborn smell after a big cooking session? Run the fan for a few minutes, then give it a quick brush‑off. It’ll clear the lingering fumes faster than waiting for the next cleaning.
Remember, a clear extractor fan means fresh air, lower energy bills, and a safer kitchen or bathroom. Follow these steps, stay safe, and enjoy the breeze again.
