How to replace a fan

Here is a step-by-step guide to replace an old exhaust fan and install a new one.

Tools and materials

  • screwdriver
  • hammer
  • screws
  • wire nuts
  • new exhaust fan

Step 1: Turn off the power

Step 2: Disconnect the vent pipe and wires

  • Disconnect the vent pipe from the old exhaust fan in the attic.

After removing the old fan, run the electrical cable into the new housing, making sure to match up each wire. Twist the wires together and secure with wire nuts.

Step 4: Mount the housing
