Broan N722 AND 722 designer series fan & light with night light & wall control Parts

For a Broan exhaust fan like model N722, the model number is typically printed on a rating label or stamped into the metal housing. We recommend checking the fan housing (inside the grille area) first; that is the most common location.

Where to look on the fan

Turn off power at the breaker, then remove the grille so you can see the housing. Check these common spots:

• Inside the fan housing near the motor plate or wiring compartment
• On the side wall of the metal housing (label or stamped text)
• Near the damper or duct connection area
• On the back side of the grille (less common)
• On the wall control plate area if your unit uses a wall control (sometimes lists series info)

Quick steps to find it (safe and fast)

1. Switch the fan off, then shut off the circuit breaker.
2. Pull down the grille and unplug the light (if equipped).
3. Use a flashlight to scan the housing for a white/silver label.
4. Write down the full model number exactly as shown (letters, numbers, and any dashes).
5. If the label is dirty, wipe it gently; do not remove it.

What the label usually includes

Label item	What it helps with
Model number	Matching the correct parts list for your fan
Series/type	Confirms the fan family and feature set
Electrical rating (volts/amps)	Verifying safe replacement parts

Why it matters

Broan fans often have similar-looking grilles and housings across multiple series. Using the exact model number prevents ordering the wrong motor plate, damper, or mounting hardware.

Parts you may match after you find the model

If you are already on the N722 parts list, these are examples of model-matched parts you can compare against what you see in the housing:

• Damper 97003932
• Housing 97008918
• Motor plt S97017066

For the Broan N722 designer series fan and light, the main parts include the fan motor assembly, blower wheel, housing, damper (backdraft flap), grille and mounting hardware, plus the wall control components. These parts work together to move air, reduce noise, and prevent outside air from flowing back in.

Common fan parts and what they do

• Motor and motor plate: spins the blower wheel to create airflow (see motor plt S97017066).
• Blower wheel: the “fan blade” inside the unit that actually moves air (see room air conditioner blower wheel 99020002).
• Housing: holds the motor and wheel, and connects to the duct path (see housing 97008918).
• Damper: helps stop backdrafts when the fan is off (see damper 97003932).
• Mounting bracket and frame: supports the unit in the ceiling or wall opening (see mounting bracket 98003036).
• Wall plate: covers the wall control opening for a finished look (see wall plt 99090676).

Quick parts map (what you’ll see vs. what it affects)

Part you notice	What it typically affects	Common symptom when it fails
Damper	Backdraft control, airflow restriction	Rattling, weak airflow, cold air coming back
Blower wheel	Air movement	Humming but little airflow, vibration
Motor plate	Motor support and alignment	Excess noise, rubbing, intermittent operation
Mounting bracket	Stability and vibration control	Shaking, buzzing, loose grille

How to identify which part you need

• Turn power off at the breaker before inspecting.
• Listen: rattling often points to the damper or loose mounting.
• Feel airflow at the grille: weak airflow often points to the blower wheel buildup or a worn motor.
• Check for vibration: look for a loose bracket, frame, or hardware.
• If you’re doing electrical checks, use a meter and safe testing practices (see how to use a multimeter to test electrical parts video).

Why it matters

Knowing the major parts helps you troubleshoot faster and order the right Broan N722 replacement part the first time, especially for common complaints like noise, weak ventilation, or backdraft.

A Broan N722 designer series fan and light typically lasts 10 to 15 years with normal bathroom ventilation use and routine cleaning. Lifespan is driven most by dust buildup, moisture exposure, and how freely the blower spins.

What affects lifespan the most

• Dust and lint buildup on the blower wheel and grille (raises load and heat)
• Moisture and corrosion from frequent showers and poor ducting
• Backdrafts from a stuck or missing damper
• Vibration from loose mounting or a worn retaining ring
• Electrical stress from loose connections or a failing wall control

Quick maintenance that adds years

• Turn power off at the breaker; remove and wash the grille.
• Vacuum the housing and motor area; keep insulation out of the fan.
• Confirm the duct is clear and the damper opens and closes freely.
• If the fan gets noisy or airflow drops, inspect the blower wheel for wobble and buildup.

Common “end of life” symptoms and what they usually mean

Symptom	Most common cause	Typical fix
Loud humming, slow start	Motor wear or drag from buildup	Clean; if unchanged, replace worn components
Rattling or vibration	Loose hardware or worn ring	Tighten; replace ring if needed
Poor airflow	Clogged duct, stuck damper, dirty wheel	Clear duct; clean or replace parts

Parts that often restore performance

If the fan is otherwise in good shape, replacing a few wear items can extend service life:

• Damper 97003932 (helps prevent backdraft and improves airflow)
• Room air conditioner blower wheel 99020002 (restores airflow and reduces vibration)
• Retaining ring 99390076 (helps keep rotating parts secure)

Why it matters

A fan that is near the end of its lifespan usually runs hotter, gets louder, and moves less air. That leads to more moisture staying in the room, which increases odors and humidity problems.
