Introduction
Go to step 1 ↓The fan is an essential component to keep your projector cool and functional. Before replacement, first check if there is dirt or dust clogging the fan's blades. Use an ESD-safe brush and/or compressed air to remove any dirt or dust buildup, then test the projector. If cleaning didn't solve the problem, and/or damage is visible, replacing the fan is the next best step. Before replacing the fan, make sure the projector is turned off, and allow it to cool completely before beginning.
