Nutone Bath Fan Lighting & Light Bulb Parts

NuTone Bath Fan Light Bulb & Lighting Parts

Bath fan lights fail for one simple reason: the bulb burns out. But when you're replacing it, grab the right OEM bulb type for your NuTone model — wattage, base type, and even light color matter for fit and performance. NuTone makes fixture-specific bulbs that deliver the right brightness without overstressing the socket.

Beyond the bulb itself, NuTone lighting parts include ballasts (for fluorescent versions), sockets, wiring harnesses, and trim rings. If your light flickers, dims, or won't turn on even with a new bulb, the ballast or socket is likely the culprit. We stock OEM bulbs and complete lighting assemblies to get your bath fan light working again.

• Standard incandescent bulbs: Most common NuTone bath fans; verify wattage (60W, 75W, 100W typical) and base type (A19, medium screw)
• Fluorescent bulb kits: Some NuTone models use compact fluorescent; includes ballast compatibility check
• LED retrofit bulbs: Modern, cooler-running alternative; verify base and wattage compatibility before substituting
• Ballast assemblies: For fluorescent NuTone units; ballast failure causes flickering or complete light failure
• Light socket assemblies: Cracked or corroded socket prevents bulb contact; OEM replacement restores connection

Find your NuTone bath fan model number on the unit's data plate (usually on the motor housing or duct collar) to confirm exact bulb type and wattage. Not sure which part you need? Use the model lookup to narrow down lighting-specific parts for your exact fan.

NuTone Bath Fan Lighting Repair FAQs

What type of bulb does my NuTone bath fan use?

Most NuTone bath fans use a standard A19 incandescent bulb rated 60W, 75W, or 100W, depending on the model. Some newer or factory-certified models use compact fluorescent (CFL) bulbs, which require a specific ballast to operate. Check your model number or look at the existing bulb — the base type and wattage are printed right on it. Never exceed the wattage rating printed on the fixture; oversized bulbs generate excess heat and can damage the socket or ballast.

My NuTone bath fan light flickers or won't stay on. Is it the bulb?

If a new bulb doesn't fix flickering, the ballast (on fluorescent models) or the light socket is the problem. A failing ballast causes intermittent light or a buzzing sound. A corroded or loose socket prevents proper electrical contact, even with a good bulb. Test with a fresh bulb first — if flickering continues, replace the ballast or socket assembly. Both are OEM parts that restore full brightness.

Can I use an LED bulb in my NuTone bath fan?

Some NuTone models accept LED retrofit bulbs, but not all — especially if you have a ballast-driven fluorescent fixture. LED bulbs require the correct base type (usually A19 medium screw) and cannot run through a CFL ballast. Always verify your model number and existing bulb type before switching to LED. For ballast-dependent fixtures, a full LED conversion kit is the right approach, not a simple bulb swap.

Where do I find my NuTone bath fan model number?

The model number is stamped on a data plate attached to the motor housing or the metal duct collar inside the cabinet or attic. It usually starts with "655" or "665" (common NuTone series). Take a photo or write down the full model number, then enter it into the Repair Clinic model lookup to see all lighting parts available for your exact fan — bulbs, sockets, ballasts, and complete light kits.

NuTone Bath Fan Model Number: Where to Look

On most NuTone bath fans, the model number is printed on a data plate attached to the motor housing or metal duct collar. You may need to remove the grille and look inside the fan cabinet or check the housing from the attic side. Write down the complete number, including any letters, then enter it in the model number search to pull up the parts matched to your unit. The model number identifies the entire bath fan, so it narrows the full catalog to compatible lighting, motor, grille, housing, and other replacement parts. That means fewer wrong orders and a faster repair.
