Replace the switch.

These are great for bathroom exhaust fans.

First thought would be a defective switch.

Better yet are humidity sensor switches with a manual On/automatic Off for odors.

Timers are great for bathroom heaters.

Here's my switch bank. From the left:

Dimmer for the lights Humidity sensor for the fan* Timer for the heater.**

• The fan can be turned on manually, but will turn off automatically after

30 minutes, assuming the humidity level is low enough. "Forgetting" is not an issue. ** The heater can only be turned on via one of the timer switches, but can be turned off manually if desired. Again, "forgetting" is not an issue.
