Why Is My Bathroom Exhaust Fan Not Turning On? Common Causes Explained

If the bathroom exhaust fan is frequently used, it may exhibit issues such as not turning on, which affects its ventilation efficiency. So, what are the reasons that a bathroom heater's exhaust fan might stop working? Let's take a look.

Reasons Why the Bathroom Heater Exhaust Fan Might Not Be Turning On

1. Faulty Capacitor: If the capacitor inside the exhaust fan is damaged, the fan will not rotate, and you will need to have a professional repair it promptly.

2. Damaged Motor: Many electrical devices operate based on motors, and if the motor is damaged, the device will not function, including the exhaust fan.

3. Circuit Issues: If the electrical circuit is not connected properly or has faults, the exhaust fan may also fail to turn on.

How to Clean the Exhaust Fan

1. You can apply a glue coating on the surface of the exhaust fan, which can attract grease and stains. First, clean the fan blades thoroughly, then apply a layer of glue. Once the glue dries, it will form a protective film that can be removed later, leaving the exhaust fan surface very clean.

2. The exhaust fan often accumulates a lot of grease, so when cleaning, be sure to use warm water and a cleaning agent. Spray the cleaning agent on the blades of the exhaust fan and wait a while before wiping it down with warm water; you'll find that the grease comes off easily.

3. An effective cleaning method is to use steam. It's quite simple and provides good results. First, boil water in a pot. Once the steam is rising, turn on the exhaust fan, and the steam will be drawn into the fan blades, cleaning the grease.

4. The exhaust fan has a water reservoir that needs to have its water changed regularly, ensuring that the water level is safe. Moreover, the reservoir can easily be clogged with debris, which will hinder exhaust efficiency, so it is advisable to clean the reservoir regularly, ideally once a week, to prevent buildup. Additionally, when using the exhaust fan, be mindful of maintaining humidity, and consider using a dehumidifier alongside it.

In summary：the above discusses the reasons why a bathroom heater's exhaust fan might not turn on. I believe everyone understands now! There are many reasons for the fan not working, and when faced with such issues, it's crucial to identify the cause to handle it better.
