About Find My Manual — We Send Product Manuals to Your Email

Quick overview

Your air conditioner’s Model Number identifies the design and features, while the Serial Number is unique to your specific unit. Both are needed for repairs, replacement parts, and warranty registration.

Common places to check

Side or Back Panel

Look for a Sticker or Plate on the side or back of window, split, or portable AC units near the power cord or vents.

Inside the Air Filter Access

Some wall-mounted or split AC units have Labels behind the Filter or Front panel.

Unit Base or Bottom

Check the bottom of portable or window units for Stickers or Labels.

Owner’s Manual or Receipt

Documents may list both model and serial numbers.

Examples & formats

Typical examples:

Troubleshooting if you can't find it

Inspect side, back, and bottom panels carefully.
Remove or open filter panels if accessible.
If still missing, check your purchase receipt or warranty card.

What to do with the numbers

Register your AC online for warranty and service support.
Provide both numbers when requesting parts or service.
Keep a photo of the label for quick reference.
Use the model number to download the correct user manual.

🧠 Tip: Air conditioner serial numbers are usually 8–12 characters long with letters and numbers (e.g., LW12345678). Models often include brand and series (e.g., LG LW8017ERSM, Frigidaire FFRE0833S1.)

🔒 Privacy & Safety Note

Do not post your serial number online — it’s unique to your unit and may be required for warranty or support verification.
