How to find Broan range hood model number?
On a Broan range hood like model B5630SS, the model number is typically printed on a rating label inside the hood canopy. We recommend checking the inside side wall (left or right) after you remove the grease filters; confirm the exact label location in the B5630SS owner's manual.
Where to look (fast checklist)
- Turn power off to the range hood at the breaker before reaching inside.
- Look on the left or right interior side wall of the hood canopy.
- Check near the blower housing area and wiring cover.
- Remove the grease filters to improve visibility (filters release using the metal latch tab).
- Write down the full model number exactly as shown (letters and numbers).
What to record from the label
Record these items so we can match the correct Broan parts (switch, blower motor, grease filter, light socket):
| Label item | Example | Why it matters |
|---|---|---|
| Model number | B5630SS | Identifies the exact range hood design |
| Part identification (if listed) | Varies | Helps match the correct replacement part |
| Electrical rating | Varies | Confirms safe, compatible electrical parts |
Why it matters
Broan range hood parts can look similar across models, but wiring, switches, and blower assemblies can differ. Using the exact model number helps ensure you get the right items such as the range hood switch assembly S99526976 or the correct grease filters.
If the label is missing or unreadable
- Check for a second label on the top of the hood base or near mounting points.
- Look for the model number on your purchase paperwork or installation notes.
- If you are troubleshooting while you search, use our DIY symptom guide: range hood doesn't work at all.

How to fix a noisy range hood fan?
On the Broan B5630SS range hood, a noisy fan is usually caused by grease buildup, a loose vent or damper, or a worn blower wheel or motor. Start with cleaning the grease filters and checking for anything rubbing or vibrating; then move to motor and damper checks.
Quick checks that fix most noise
- Turn power off at the breaker before touching wiring or the blower.
- Remove and clean the grease filters (the manual recommends monthly cleaning); reinstall them fully seated.
- Check the vent path for rattles: loose duct, loose mounting screws, or a damper flap tapping.
- Run the fan on low, medium, and high; note if noise changes with speed (helps pinpoint motor vs. vibration).
- Confirm the hood is vented correctly for your setup (ducted to outdoors for ducted installs).
Most common causes and what to do
| Noise type | Most likely cause | What we do first |
|---|---|---|
| Rattle or tapping | Vent damper flapping or loose duct | Inspect/secure ducting; check damper movement |
| Buzzing or humming | Motor bearings wearing, debris in blower | Inspect blower area; consider motor replacement |
| Vibration | Hood not tight to wall, filters not seated | Tighten mounting points; reseat filters |
| Grinding/scraping | Blower wheel rubbing housing | Inspect for bent wheel or shifted motor mount |
Parts that commonly solve a noisy fan
If cleaning and tightening do not stop the noise, replacement parts are the next step:
- Range hood blower motor assembly S99526974 (for loud humming, squeal, or rough running)
- Range hood vent damper S99526983 (for tapping or fluttering in the duct)
- Broan range hood grease filter, 2-pack S97018029 (if filters are warped or won’t seat)
Why it matters
A noisy range hood fan is often a warning sign of restricted airflow or a failing motor. Fixing it restores proper ventilation, reduces vibration wear on the hood and ductwork, and helps prevent grease buildup on the fan and filters.
For model-specific removal steps and maintenance details, use the B5630SS owner's manual.

What are the parts of a range hood called?
A range hood is typically made up of the hood body (canopy), venting pieces, controls, lights, and filters. On the Broan B5630SS, you will commonly see the hood, decorative flue, damper or duct connector, grease filters, light covers and bulbs, and the front-panel push-button controls (fan speeds and light on/off). See the B5630SS owner's manual for the exact component names used for your hood.
Common range hood part names (and what they do)
- Hood canopy (hood body): captures smoke, steam, and grease above the cooktop
- Decorative flue (duct cover): covers the duct path above the hood
- Damper or vent damper: helps prevent backdraft when the fan is off
- Blower (fan) and motor: moves air through the ducting
- Grease filters: trap grease before it reaches the blower and duct
- Lights (bulbs, lens/cover, socket): illuminate the cooking surface
- Control panel or switch assembly: turns the fan and lights on and off and selects speed
B5630SS parts you will hear us reference most
These names match what you will see in typical parts lists and service discussions:
| Part name | What it affects | Common symptom when it fails |
|---|---|---|
| Grease filter | Airflow and grease capture | Grease buildup, reduced airflow |
| Vent damper | Draft control | Cold air backdraft, rattling |
| Blower motor assembly | Fan operation | Fan does not run, noisy fan |
| Switch assembly | Fan speeds and light control | Fan or lights not responding |
If you are shopping by name, two common B5630SS replacements are the Broan range hood switch assembly S99526976 and the range hood vent damper S99526983.
Why it matters
Using the correct part name helps you match the right diagram and order the right replacement. It also speeds up troubleshooting, for example separating an airflow issue (filters, damper, ducting) from an electrical issue (switches, transformer, motor).

Is Broan a good brand for range hoods?
Yes. Broan is a solid, reliable brand for residential range hoods, and the Broan B5630SS is built around straightforward, serviceable components (filters, lights, fan speeds) that make it a good value for everyday cooking ventilation. For model-specific operation and care details, use the B5630SS owner's manual.
What “good” means for a range hood
A good range hood brand consistently delivers dependable airflow, easy maintenance, and readily available replacement parts. With Broan, we typically see strengths in practical design and long-term serviceability.
Common reasons customers choose Broan:
- Simple push-button controls for light and fan speeds
- Easy-to-remove grease filters that are meant to be cleaned monthly
- Standard halogen lighting on this model (Type JC, 12V, 20W max, G-4 base)
- Widely available service parts for repairs instead of full replacement
What to check before you buy or keep using one
Even a “good” hood can disappoint if it is installed or maintained poorly. Focus on these items:
- Vent path: short, smooth duct runs move air better than long, restrictive runs
- Damper operation: a sticking damper can reduce airflow and increase noise
- Filter condition: clogged grease filters reduce performance fast
- Fan behavior: surging, intermittent operation, or weak suction points to a control or motor issue
| Area | What you want | What causes complaints |
|---|---|---|
| Airflow | Steady capture of smoke/odors | Dirty filters, blocked duct, stuck damper |
| Noise | Acceptable sound at low/med | High speed noise, vibration, loose mounting |
| Maintenance | Quick filter and bulb access | Neglected cleaning, wrong bulb type |
Parts that most often affect performance
If performance drops, these are the most common service items we see on the B5630SS:
- Range hood blower motor assembly S99526974 (weak airflow, grinding noise, won’t run)
- Broan range hood grease filter, 2-pack S97018029 (poor capture, greasy residue)
- Broan range hood switch assembly S99526976 (fan speeds or lights not responding)
Why it matters
A dependable hood protects cabinets and walls from grease buildup and helps remove heat, smoke, and odors. Keeping filters clean monthly and using the correct bulbs helps the Broan B5630SS perform the way it was designed.
