What should I do if the toilet exhaust fan is broken?

First, what should I do if the toilet exhaust fan is broken?

1, first check whether the socket is electrified, listen to whether the motor hums after electrification, and carefully turn the fan with a screwdriver. If the fan blade can rotate, it is a capacitor fault and cannot be started by the motor.

2. Remove the motor housing and carefully check whether the threaded end falls off or is welded incorrectly. Find the end of the dropped wire and wrap it with electrical tape.

3. If the exhaust fan is not cleaned for a long time, it is easy to accumulate dust, so check and clean it.

If there is something wrong with the motor, you can only find a professional master to repair it.

Second, how to choose a good ventilator?

1. When installing the ventilator, there should be a ceiling, and an air outlet above the ceiling should be directly discharged to the outside.

2. The ventilator has a roof when it is installed. The roof must reserve an air duct to be directly evacuated to the outside, and some air duct ventilator should be selected. At the same time, high wind pressure will directly exhaust the air to the outside.

3. When installing the ventilator, there is a ceiling, and the ceiling must reserve an air duct to evacuate directly to the outside. Some air duct ventilator fans must be exhausted to the outside through the air duct installed on the ceiling, or some large buildings can use the all-air duct ventilator that hides the exhaust after the gas flow in the pipeline accelerates.

4, directly installed in the wall hole, can exhaust indoor dirty air to the outside, can breathe in fresh air, we can choose the louver ventilator, and the louver ventilator also belongs to the partition ventilator in the installation mode.

5. When installed on the glass doors and windows of rooms, shopping malls, hotels and bedrooms, ventilators must be used.
