How to replace bathroom fan

Because the connections and wiring are already in place, installing a new bathroom fan won't take long. First, gently remove the old fan and disconnect the vent pipe and connections.
The new fan will then be installed. Reattach the wires and vent pipe, and your fan is ready to go. Just make sure you're familiar with electrical wiring before you start!

2. Take Out the Old Fan​

To begin, I turned off the electricity to the bathroom so that I could safely detach the wire without fear of electrocution! I then removed the old fan in order to select a replacement that would fit without requiring a larger hole in the drywall. After removing the fan, I temporarily taped a plastic bag over the opening.
Because the fan is also linked to the light and there is no window in the bathroom, I installed a work light outside the door.
I taped plastic to the walls and the floor of the bathroom to collect any insulation/mess that could fall down when I was working in the attic later.

3. Examine What You Have So That You Can Make Appropriate Purchases​

I examined the old ducting in the attic and determined that the original four ′′ pipe linked to the vent was badly built and had many holes. I also discovered that the builder made an incorrectly sized hole in the roof, which explained the gaps. The image depicts the appearance of the old duct (and fan).
I discovered a specialty fan store that caters to the construction sector but is also open to the general public. I brought the old fan with me to get the same dimensions to suit the ceiling hole, but I updated it to a whisper-quiet fan (just one song). Any fan that is less than 1.5 sones is considered quiet, so keep that in mind when shopping.

4.The Hard Work Begins​

To protect myself from the scratchy insulation, I dressed in a white Tyvek coverall like the one shown. I also wore a heavy-duty mask: if you've ever had mice in your attic, you know that breathing in small particles from the mess they leave behind can make you sick. Wearing a mask is necessary to avoid breathing in any contaminants.

5.Gather Materials​

I positioned a ladder beneath our attic access and removed the panel (ours is located in the bedroom closet). I packed all of my gear in a box to keep it all together and make the journey only once. A drill, screws, screwdriver, tin snips, duct fittings, fan, electrical bushing, silver tuck tape, and other tools were included. I also brought a strong light with me on an extension cord to see (the light was connected to another electrical power supply that was still operational).

6.Installation is the sixth step​

I removed the plastic bag, centered the new fan body over the ceiling hole, and screwed it into the joists. A metal strip was connected to the back to assist in securing it farther to the joist (it can lessen side-to-side vibration). Depending on where your hole is between the joists, you may need to attach one to four of these strips to fix it.

7.Insulate and test the electrical connection​

Before finishing the insulation, I reconnected the electricity to ensure that everything was working properly. Then, as a precaution, I shut off the electricity again and went back into the attic to wrap the pipe in insulation and tie it down with a cord (I reused the original insulation).

When Should a Bathroom Fan Be Replaced?​

According to Mark Wahlberg - an author of Ceiling Fans Living, when a fan stops clearing a bathroom of steam during a bath or shower, starts making noises, or breaks completely, replacing the device is typically the most appropriate and cost-effective remedy. Newer versions are often quieter and more efficient than their predecessors, so even an extremely noisy unit may require replacement.
Bathroom fans aren't difficult to install. A small electric motor drives a fan, the blades of which force air through a duct to the exterior of a room or house, removing steam and odors. Most current fan systems are housed in a modular unit—a box containing all of the electronics and mechanical components. This simplifies the replacement process significantly.
Taking apart the ceiling unit to repair a noisy or underperforming fan is all too frequently a futile exercise. Most current fans have sealed bearings that cannot be oiled (if they can be accessible at all).
