How do I know what model range hood I have?
Your Frigidaire range hood’s model number is printed on the rating plate (serial plate) inside the hood. On model FHWC3640MSB, you find it by removing the grease filter and the left side panel; the plate is on the left side.
Follow the location steps shown in the FHWC3640MSB owner’s manual. In most kitchens, you can access the plate from underneath the hood.
- Turn the hood off.
- Remove the range hood grease filter.
- Remove the left side panel.
- Look on the left interior side for the rating plate.
- Write down both the model number and the serial number.
The rating plate typically lists the key identifiers you need for parts and service.
| Item on label | What it’s used for | Example you’ll see |
|---|---|---|
| Model number | Matching parts diagrams and parts | FHWC3640MSB |
| Serial number | Identifying production run details | Varies |
| Electrical ratings | Verifying power requirements | Varies |
We use the exact model number to match the correct Frigidaire parts (like the correct grease filter, lamp, or vent damper) and to avoid ordering a look-alike part that will not fit.
- Copy the model number exactly as printed (letters and numbers).
- Copy the serial number too; it helps with version changes.
- If the label is greasy, wipe it gently so characters are readable.
- Keep the information with your paperwork for future repairs.

Can I look up Frigidaire parts by model number?
Yes. For your Frigidaire range hood model FHWC3640MSB, looking up parts by the full model number is the most reliable way to match compatible replacement parts (filters, lights, motor components) and avoid ordering the wrong item.
The model and serial information is on the serial plate inside the hood. On this model, you typically remove the grease filter and the left side panel to view the serial plate; the exact steps are shown in the FHWC3640MSB owner's manual.
Quick checklist
- Turn off power to the range hood at the breaker before removing panels.
- Remove the grease filter.
- Remove the left side panel.
- Read the serial plate and copy the model number exactly: FHWC3640MSB.
- Use that model number when searching for parts.
Model-number lookup narrows results to parts that fit your exact hood configuration (ducted vs. recirculating, lighting style, control layout).
| What you need | Common part type | Example for FHWC3640MSB |
|---|---|---|
| Hood light not working | Lamp or light socket | Lamp 5304466038, range hood light socket 5304487848 |
| Poor smoke/odor removal | Grease filter or charcoal filter | Range hood grease filter 5304491588, range hood charcoal filter 5304486303 |
| Weak or noisy airflow | Motor assembly or venting components | Motor assembly 5304491589, range hood vent damper, 3-1/4 x 10-in 5304490028 |
Range hood parts are highly model-specific. Using FHWC3640MSB (not a partial number) helps ensure the part mounts correctly, connects properly, and performs as designed.

What are the parts of a range hood called?
A range hood is made up of the hood body (canopy), a blower (fan and motor), filters, lights, and the control panel; on the Frigidaire FHWC3640MSB, you will also see grease filtration and optional charcoal filtration depending on whether it is ducted or recirculating (details in the FHWC3640MSB owner's manual).
- Canopy/hood body: captures smoke, steam, and grease above the cooktop.
- Blower system: moves air; includes the fan and motor.
- Grease filter: traps grease before it reaches the blower and ductwork.
- Charcoal filter (recirculating setups): reduces odors when air is not vented outdoors.
- Lights and lamp housings: illuminate the cooking surface.
- Controls/control panel: light on/off and fan on/off with speed selection.
These names are common on parts lists and match how replacement parts are sold.
| Parts list name | What it usually refers to | Example for this model |
|---|---|---|
| Lamp | The light bulb used in the hood | Lamp 5304466038 |
| Range hood grease filter | Metal filter under the hood | Range hood grease filter 5304491588 |
| Range hood charcoal filter | Odor filter for recirculating mode | Range hood charcoal filter 5304486303 |
| Motor assembly | Blower motor and related mounting components | Motor assembly 5304491589 |
| Range hood vent damper | Backdraft damper at the duct outlet | Range hood vent damper, 3-1/4 x 10-in 5304490028 |
Knowing the correct part names helps you order the right replacement the first time and troubleshoot faster. For example, weak airflow often points to a dirty grease filter or a blocked damper, while “no lights” can be a lamp or light socket issue.
- Check whether your hood is ducted (vents outside) or recirculating (uses charcoal filtration).
- Look for the model/serial rating plate inside the hood; it confirms you are shopping for FHWC3640MSB parts.
- Match the part name to the symptom: airflow issues (filters, damper, motor) vs. lighting issues (lamp, socket).
- Use the control layout (light on/off, fan on/off, speed buttons) to confirm you are diagnosing the right circuit.
