If you're looking to replace the bulb in your Broan bathroom fan with light, you've come to the right place. In this guide, we'll walk you through the process step by step, ensuring you get the right bulb and install it safely. Let's dive in.
Understanding Your Broan Bathroom Fan with Light
Before we start, it's crucial to understand the basics of your Broan bathroom fan with light. These units typically use an integrated light fixture, usually an incandescent or compact fluorescent (CFL) bulb. Some newer models may use LED bulbs. The fan itself is usually controlled by a wall switch, while the light may have its own switch or be controlled by a pull chain.
Choosing the Right Replacement Bulb
Bulb Type
First, you need to determine the type of bulb your Broan fan uses. The most common types are incandescent, CFL, and LED. Incandescent bulbs are the oldest type and are being phased out due to their inefficiency. CFLs are more energy-efficient but contain mercury, making them more difficult to dispose of. LED bulbs are the most energy-efficient and have a long lifespan.

Once you know the bulb type, check the packaging or the existing bulb for the base type. The most common bases are Edison screw (E26 or E27) and bayonet (B22 or B27). Most Broan fans use Edison screw bases.
Wattage and Lumens
Next, you'll need to match the wattage of the new bulb to the old one. This is important for safety and to ensure the fan's motor isn't overloaded. However, it's also important to consider lumens, which measure the amount of light emitted. A higher lumen count means a brighter light.
As a general rule, a 40W incandescent bulb is equivalent to a 9W LED bulb with around 450 lumens. So, if your current bulb is a 60W incandescent, you'll want to replace it with a 13.5W LED bulb with around 800 lumens for the same level of brightness.

Safety First: Preparing to Replace the Bulb
Before you start, ensure the power to the fan is turned off at the circuit breaker. This is crucial for your safety. Also, make sure the fan is cool to the touch before you begin.
Step-by-Step: Replacing the Bulb
- Remove the light fixture cover. This is usually done by unscrewing it or pressing and turning it.
- Remove the old bulb by twisting it counterclockwise until it's loose, then pull it straight out.
- Insert the new bulb by lining up the base with the socket and twisting it clockwise until it's tight. Be careful not to overtighten.
- Replace the light fixture cover.
- Turn the power back on at the circuit breaker and test the new bulb.
Troubleshooting Common Issues
If your new bulb isn't working, here are a few things you can check:
| Issue | Solution |
|---|---|
| Bulb doesn't light up | Check that the bulb is fully screwed in. Try it in a different socket to see if it works. |
| Bulb flickers or dims | This could be a sign of a bad connection or a problem with the fan's wiring. You may need to call an electrician. |
| Fan doesn't run | Check that the fan's switch is turned on. If it's still not running, the motor may be faulty. |
If you're unsure about any part of the process, don't hesitate to call a professional. Safety should always be your top priority.
