How To Replace Broan Bathroom Fan

How to Replace a Broan Bathroom Fan

A bathroom fan plays a crucial role in maintaining a healthy and comfortable bathroom environment. It effectively removes moisture, odors, and pollutants, preventing the growth of mold and mildew. However, bathroom fans can malfunction or wear out over time, requiring replacement. If you have a Broan bathroom fan that needs replacing, this guide will provide comprehensive step-by-step instructions on how to do it yourself.

Assessing the Situation and Gathering Supplies

Before embarking on the replacement process, it is essential to assess the situation and gather the necessary supplies. First, disconnect the power to the bathroom fan circuit breaker at the electrical panel. This ensures safety during the entire process. Next, visually inspect the old fan to determine the exact model and size. This information will help you choose a compatible replacement unit.

Gather the following supplies for a successful replacement:

A new Broan bathroom fan matching the old unit's size and features
A screwdriver set (Phillips and flathead)
A wire stripper
Electrical tape
A voltage detector (optional but recommended)
A level
Safety glasses
Work gloves

Removing the Old Bathroom Fan

Once you have gathered the necessary supplies, follow these steps to remove the old bathroom fan:

Remove the cover plate: Using a screwdriver, remove the screws securing the cover plate to the fan housing. Carefully detach the cover plate and set it aside.
Disconnect the wiring: Locate the wires connected to the fan motor. Note the color coding of each wire. Use a voltage detector to confirm that the power is off. Carefully disconnect the wires from the fan motor terminals.
Release the fan housing: Locate the screws or clips securing the fan housing to the ceiling. Remove these fasteners and carefully detach the housing from the ceiling opening. The fan housing is attached to the vent pipe, so gently pull it away from the ceiling and vent.
Remove the vent pipe: If the vent pipe is connected to the fan housing, detach it from the fan housing. The vent pipe can be held in place by screws, clips, or a slip fit. Use a screwdriver and gently pull the pipe away from the fan housing.

Installing the New Bathroom Fan

After successfully removing the old fan, you are ready to install the new Broan bathroom fan. Follow these steps:

Attach the vent pipe (if necessary): If the new fan requires a different vent pipe, attach the new pipe to the fan housing using the appropriate fasteners. Make sure the pipe is securely connected and properly aligned.
Attach the fan housing to the ceiling: Align the new fan housing with the ceiling opening. If the fan has built-in mounting brackets, secure them to the ceiling using screws or clips provided. If the fan does not have brackets, use the existing mounting holes from the old fan for attaching the new fan housing securely.
Connect the wiring: Match the color-coded wires of the new fan to the corresponding wires in the ceiling. Use wire strippers to expose approximately ½ inch of wire on each end. Connect the wires carefully, ensuring they are securely connected to the terminals. Use electrical tape to secure each wire connection.
Attach the cover plate: Place the cover plate over the fan housing and secure it using the screws provided. Ensure the cover plate is properly aligned and sits flush against the ceiling.
Test the fan: Turn the power back on at the circuit breaker. Test the new fan by turning on the light switch that controls it. Ensure the fan operates smoothly and at the desired speed.

Additional Considerations

While following the above steps provides a clear guideline for replacing a Broan bathroom fan, consider these additional points for a successful installation:

Check for compatibility: Before purchasing a new fan, verify its compatibility with your existing vent pipe and electrical wiring. Ensure it has a similar CFM (cubic feet per minute) rating to the old fan, as this affects its ventilation efficiency and effectiveness.
Use a level: When attaching the fan housing to the ceiling, use a level to ensure it is properly aligned and mounted straight. This creates a balanced and aesthetically pleasing installation.
Hire a professional: If you are unsure about any aspect of the installation process, consult with a licensed electrician for assistance. Attempting to replace a bathroom fan without proper expertise can lead to safety hazards or improper installations.
