The function of this in the bathroom is to prevent electrical shock in the bathroom. Locate the master GFCI outlet and hit the set button. Power will be restored.

The wall switch

Bathroom exhaust fan problems can be due to housing outlet

Some technology has housing outlets. Check the outlet if there is no problem with the wall switch. When you remove the bath van cover, you will locate the outlet. Unplug the motor plug and test if there is a power supply to the housing outlet.

A burnt motor

If the entire test recommended above has proved negative in the drive to discover the cause of the bathroom exhaust fan problems; check the motor of the device. If the motor is burnt, issues will come up. When you plug the motor into an extension cord that is in turn connected to a good outlet; the motor should turn on.

If the cover is dirty, simply have it cleaned up and you are good to go. A clogged and dirty cover will block about 90% of the air that is supposed to go into circulation.

When fan blades fail to spin properly

Just as is the case with the fan cover, a dirty fan blade will produce issues that will give you cause for worry. Remove the cover of the fan blade and push the fan with your finger. If it does not spin freely, then you need to oil the fan. Where the fan still refused to rotate freely; then you need to change the fan.

The vent

Turn on the fan and check the outside of the vent cover. The common phenomenon here includes bird’s nest in the vent. When the flapper of the vent cover is closed, there will be issues. You can shine a flashlight into the vent hose to know if the problem is from there.
