Replacing a bathroom exhaust fan with light might seem like a daunting task, but with the right tools, instructions, and a bit of patience, you can accomplish it yourself. In this comprehensive guide, we will walk you through every step of the process, from identifying when your bathroom exhaust fan needs replacement to installing a new one and even troubleshooting common issues.
To replace a bathroom exhaust fan with light, first, turn off the power at the circuit breaker. Remove the old fan grille, disconnect the motor, and remove the fan housing. Choose a new fan based on your bathroom’s size and the fan’s CFM rating. Enlarge the hole in the ceiling if necessary, attach the new fan’s duct and housing, connect the wiring, install the fan, and secure it with screws. Turn the power back on, test the new fan and light, and install the cover if everything works correctly.
Signs Your Bathroom Exhaust Fan with Light Needs Replacement
Before we dive into the replacement process, it’s essential to know when your exhaust fan needs replacement. Here are some common signs:
- Loud Noise: If your exhaust fan is making more noise than usual, it could be a sign of a dying motor.
- Moisture Problems: If the air in your bathroom feels thick and stuffy, it’s a sign that your exhaust fan isn’t effectively removing moisture.
- Persistent Odors: If odors linger in your bathroom even with the exhaust fan running, it might be time for a replacement.
- Slow or Non-spinning Fan: If the fan is slow to start or doesn’t spin at the speed it once did, it’s time for a replacement.
- Burning Smell: A burning smell from the fan could indicate an electrical problem. Replace it immediately to avoid potential fire hazards.
- High Humidity Levels: Excessive humidity leading to issues like mold growth, peeling paint, or a stuffy atmosphere indicates a non-working exhaust fan.

Selecting the Right Type and Size of a New Bathroom Exhaust Fan with Light
When choosing a new bathroom exhaust fan with light, consider the size of your bathroom, the fan’s noise level, its energy efficiency, and its CFM (Cubic Feet per Minute) rating, which indicates how much air the fan can move. The Home Ventilating Institute recommends 1 CFM per square foot of bathroom area, with a minimum of 50 CFM for any size bathroom.
Installing the New Bathroom Exhaust Fan with Light
Once you’ve removed the old exhaust fan and selected a new one, it’s time to install it. Follow these steps:

- Connect the Wiring: Connect the wiring as per the manufacturer’s instructions.
- Install the Fan: Install the fan into the housing, making sure the fan’s outlet is aligned with the duct.
- Secure the Fan and Test: Secure the fan with screws, turn the power back on, and test the new fan and light.
- Install the Cover: If everything works correctly, install the cover.
Troubleshooting Common Issues
If the new bathroom exhaust fan with light doesn’t work as expected, here are some troubleshooting tips:
