Shut down the unit

When determining the cause of overheating bearings in a ventilating fan, the initial step is to shut down the unit. This action is essential for safety reasons; overheating can lead to catastrophic failure or further damage to the equipment, and operating it in this state can pose a risk to personnel. By shutting down the unit, you create a safe environment for inspection and troubleshooting.

Once the unit is powered off, you can proceed safely to investigate other potential causes like the lubrication system, the fan's motor, or the surrounding airflow conditions. Each of those aspects plays a critical role in the operation of the fan and could contribute to the overheating issue. Thus, shutting down the unit is a crucial first step that allows for a thorough and safe examination of the problem.
