Resetting a radiator fan is the process of restoring it to its default settings. This may be necessary if the fan is malfunctioning or if you want to change its settings. The steps for resetting a radiator fan will vary depending on the make and model of the fan, but the general process is as follows:
1. Unplug the fan from the power source.
2. Locate the reset button on the fan. This button is usually small and recessed, and it may be located on the side or bottom of the fan.
3. Press and hold the reset button for 5-10 seconds. The fan will then reset to its default settings.
4. Plug the fan back into the power source and turn it on.
