How to Replace Bathroom Exhaust Fan

Assemble all the required tools

You need to put everything in order before you begin the actual work. Even as you assemble the tools, ensure that you have the correct type of fan. It is important to replace an old fan with a new one of the same model. Another important thing to look for is the licensing. In some regions, it is illegal to carry out the replacement with the proper license. When you have all the above in place, you are all set for the work.

Remove the old fan

Begin by taking off the cover. Covers are either held by screws or even snaps. Identify the type which holds the cover and use the appropriate method to take it off. Remember to remove the cover gently to avoid damaging it. It is quite delicate.

Disconnect the wiring of the old fan

Remember that the old fan had the wiring already in place. You should exercise some care so as not to damage the wiring as you do the disconnection. These wires do carry electric power. To be safe, you better switch the power off totally. The wires are always concentrated inside its housing unit.

When the power is off, you can then remove the wires from the housing. If the housing has connectors, you will also need to remove it. It is when all the wires have been disconnected that you can connect the new fan.

Detach the vent pipe and remove its housing

This is a long connection between the roof and the fan itself. Unscrew the screws to set it free, and if it is held on to the position by a tape, just peel it off. Then pull out the vent pipe slowly but carefully until it comes out of the housing of the fan. Then remove the vent fan from its place. This is in preparation for installing a new one in place of the old one.

You have successfully removed what needs to be removed and it is now time to put back a new one.

Readjust the ceiling hole.

This may not be a necessary thing to do, not unless the size of the fan changes significantly. Make the correct measurement so that you do not cut your ceiling unnecessarily. If the new fan is larger than the old one, you will have to cut out some pieces. Should the new fan be smaller, then you will have to patch the ceiling to reduce the size of the hole.

Put back the vent pipe

Remember that you had removed the vent pipe initially when you were removing the housing unit. It is not necessary to change the vent pipe, as the same old one will do well. Slide it in carefully till it is fully in place and fasten it securely using a tape.

Reattach the electricals

Double-check again to ensure that power is not running in the wires. Carefully, connect it back to the correct terminals. If you connect wrongly, you may end up burning the fan when the power comes on. The good thing is that the wires are colored by the terminals. The colors are white, black and yellow. The corresponding terminals are assigned the same colors too. Once done, push the connections back to the housing, and cover it with the junction cover.
