How to clean filters on KitchenAid vent hood?
For the KitchenAid KXW9748YSS0 vent hood, we clean the grease filters by turning the hood off, removing the filters, washing them with warm water and mild detergent (or using a dishwasher if the filter is dishwasher-safe), then reinstalling them once fully dry. See the KXW9748YSS0 owner’s manual for your exact filter removal steps.
Step-by-step: cleaning the grease filters
- Turn the vent hood off and let the lights and surfaces cool.
- Remove the grease filter(s) from the underside of the hood.
- Wash in a sink with warm water and a grease-cutting dish detergent.
- Rinse thoroughly and let the filter dry completely.
- Reinstall the filter(s) and confirm they seat securely.
Dishwasher vs hand-washing (what to expect)
Some metal mesh or baffle-style filters can go in the dishwasher, but they may discolor over time. Hand-washing is gentler and helps preserve the finish.
| Method | Best for | Watch-outs |
|---|---|---|
| Hand-wash | Regular maintenance, heavy grease | Takes a little longer |
| Dishwasher | Convenience | Possible discoloration, trapped debris if not rinsed |
When cleaning is not enough
If the filter is bent, won’t sit flat, or stays sticky after cleaning, replacement is the better fix. For this model, a common replacement is the range hood grease filter W10351890.
Why it matters
Clean filters keep airflow strong, reduce smoke and odor buildup, and help protect the blower and control housing from grease contamination.

Why is my range hood fan not working but light is?
If your KitchenAid range hood model KXW9748YSS0 light works but the fan will not run, the hood is getting power but the fan circuit is failing. The most common causes are a bad fan switch, a failed blower motor, or a wiring connection issue between the control and the blower.
Quick checks we recommend first
- Turn off power at the breaker before opening any panels.
- Confirm the fan is not set to a delay or special mode (if equipped); check the KXW9748YSS0 owner’s manual.
- Remove and clean the grease filters; heavy grease buildup can restrict airflow and make the blower seem weak.
- Spin the blower wheel by hand (power off); it should rotate freely without scraping.
- Inspect the damper for sticking or binding that can load the blower; see range hood vent damper W11156393.
Likely causes (in order)
| Symptom | Most likely cause | What to do next |
|---|---|---|
| Fan does nothing on any speed | Failed switch or control housing issue | Check the fan switch and wiring in the control area; consider rocker switch W10351934. |
| Fan hums but will not start | Blower motor failing or wheel jammed | Check for obstructions; if wheel is clear, replace the blower assembly. |
| Fan runs intermittently | Loose connection or failing switch | Reseat connectors, look for heat damage, then replace the switch if needed. |
| Fan runs but airflow is poor | Grease filter clogged or damper stuck | Clean/replace filter; free up or replace damper. |
Parts that commonly fix this on KXW9748YSS0
- Rocker switch W10351934 (fan speeds not responding)
- Range hood blower assembly W11499036 (motor not running, humming, or noisy)
- Range hood grease filter W10351890 (airflow restriction, heavy grease buildup)
- Range hood vent damper W11156393 (damper stuck closed or rattling)
Why it matters
A non-working fan leaves heat, smoke, and grease in the kitchen. It also allows grease to build up inside the hood, which can shorten the life of the blower motor and switches.

What are the parts of a range hood called?
Most range hoods, including the KitchenAid KXW9748YSS0 professional hood, are made up of a hood body (canopy), a venting path (duct and damper), a blower (fan), lighting, filters, and a control area. The exact names and layout for your hood are shown in the KXW9748YSS0 owner's manual.
Common range hood part names (and what they do)
- Canopy (hood body): captures smoke, steam, and grease above the cooktop
- Blower (fan) assembly: moves air through the hood and into the ducting
- Vent damper: helps prevent outside air from backdrafting into the kitchen
- Grease filter: traps grease before it reaches the blower and ductwork
- Control housing / control panel: holds switches and wiring for fan and lights
- Light assembly: bulbs, sockets, and trim pieces that illuminate the cooktop
KXW9748YSS0 parts you will commonly see listed
These are typical names you will see when shopping for KitchenAid range hood parts:
| What you see in parts lists | What it’s for | Example from this model |
|---|---|---|
| Grease filter | Captures grease and helps protect the blower | Range hood grease filter W10351890 |
| Blower assembly | Fan motor and wheel that move air | Range hood blower assembly W11499036 |
| Vent damper | Reduces backdraft and rattling | Range hood vent damper W11156393 |
| Control housing | Encloses switches and wiring | Control housing W11387938 |
| Light bulb / socket / bezel | Lighting components | Range hood light bulb WPW10294005 |
Why it matters
Using the correct part name helps you match the right replacement to the symptom. For example, weak airflow usually points to the grease filter, blower assembly, or vent damper, while dead lights often involve the light bulb, socket, or a control switch.
Quick tips when identifying a part
- Start with the symptom: airflow, noise, lights, or controls
- Check whether the issue is mechanical (rattle, vibration) or electrical (no power, intermittent)
- Compare the part’s location on the hood to the diagrams in the manual
- For electrical checks, use safe testing practices and shut off power at the breaker
- Match by model number KXW9748YSS0 to avoid fit issues
