The fan is on, but it doesn’t get rid of the smell or wetness well.

Solution: Look for clogs along the whole venting system, including the cover on the outside vent. Get rid of anything that is in the way, like bird nests, leaves, or piled-up dirt.

4. Humidity Sensor Malfunctions (if applicable)

The fan doesn’t turn on by itself when it’s hot outside.

Solution: Change the settings for the humidity level. Use a soft cloth to lightly clean the sensor to make sure it’s not clogged with dust.

FAQ

How do I know if my bathroom extractor fan needs replacing or just repairing?

If your fan isn’t too old and the problems are small, like clogs or broken parts that need to be replaced, a repair might be enough. But if the fan is old, often breaks down, or has a motor that is completely burned out, it might be cheaper to get a new one.

How often should I clean my bathroom extractor fan?

Cleaning it depends on how often it’s used, but every three to six months is a good rule of thumb. Regular cleaning keeps dust and lint from building up, which can make the fan less effective and even cause fires.

What is the average lifespan of a bathroom extractor fan?

Depending on the type and how often it is used, a fan can last anywhere from 5 to 10 years if it is well taken care of. The fan can last longer if it is cleaned regularly and fixed quickly. A fan may need to be replaced if it makes a lot of noise, doesn’t work as well, or won’t turn on at all.

Should my bathroom extractor fan be vented outside?

Yes, that’s right. It is very important to have vents that go to the outside so that water doesn’t go back into attics or walls and cause mould and structural damage. The vent should go straight outside, not just into the roof or some other room inside.
