Why model and serial numbers matter
Almost every warranty conversation opens with two questions: the model number and the serial number. They identify the exact unit — its production batch, features and applicable service parts.
Reconstructing them later is difficult. Once product packaging is discarded and the printed sticker on the appliance fades or gets covered during installation, the numbers can be genuinely hard to retrieve.
Refrigerator
The rating plate on a refrigerator is commonly found in one of a few places. Check the manual for the exact position of your model.
- Inside the fresh-food compartment, on a side wall.
- Near the top interior of the compartment, above the shelves.
- On the back of the unit near the compressor housing.
- Along the door frame or the base near the kickplate.
Washing machine
Washing machine rating plates are commonly located near the door or on the rear panel.
- Around the door opening or inside the door frame.
- On the back panel, near the top or bottom.
- Behind the detergent drawer in some models.
Air conditioner
Split ACs carry rating plates on both the indoor and outdoor units — both are useful to record. For window units, look on the side or rear of the chassis.
- On the side of the indoor unit, often below the front cover.
- On the rear or side of the outdoor unit.
- On the top or side panel of a window unit.
Television
Televisions almost always carry the rating plate on the rear panel.
- On the back of the panel, often near the ports.
- On the base or stand for some larger models.
- In the settings menu — many TVs display model and serial digitally under About or Support.
Microwave and water purifier
Kitchen appliance plates are commonly on the side, rear or inside the door.
- Microwave: on the rear panel or inside the door frame.
- Water purifier: on the rear, base or inside the front cover.
- Small kitchen appliances: usually on the base.
Record it once, well
The best time to record a serial number is on the day the appliance is delivered or installed. Take a clear photograph of the whole plate — not just the number — so the full context is available later.
Model/serial capture checklist
- Photographed the rating plate in good light.
- Included the surrounding text (electrical ratings, manufacturing date).
- Attached the photograph to the product record.
- Noted the model and serial number in the record as text.
- Re-photographed the plate if the original ever fades.
When in doubt, check the manual
Placement varies by brand and model. If the rating plate is not obvious, the manual or manufacturer support page shows the exact location for your specific model.
Frequently asked questions
Is the model number the same as the serial number?
No. The model number identifies the product family. The serial number identifies your specific unit.
What if the rating plate is unreadable?
Check the original box, the manual, the seller invoice or the manufacturer's support page. Many manufacturers can also help identify a unit from a photograph.
Can I find the model number in an appliance's settings?
Some smart appliances and televisions show model and serial details in an About or Support menu. Not all appliances offer this — check the manual.
Should I record the manufacturing date too?
Yes. It sits on the same rating plate and is often useful for warranty and service conversations.
Does CheckMyWarranty read the number from a photo?
No. The app stores the photograph and the text you enter. It does not extract or interpret content from images.
Are two units of the same model interchangeable?
Not for warranty purposes. Even identical models have different serial numbers, and warranty records are tied to the specific unit.
