Tips for Hard-to-Read Labels

The label is faded or dirty. What now?

Try using a bright flashlight from a side angle to create shadows in the embossed text. You can also carefully rub a graphite pencil over embossed lettering to make it stand out. For dirty labels, use a damp cloth but avoid harsh cleaners that might dissolve the ink.

Can I find the serial number in the software?

expand_more
Yes, for modern "smart" appliances and electronics. Check the settings menu under "About," "System Information," or "Network Status." On many smart fridges, it's also located in the 'Info' section of the external touchscreen display.

Why do I need the serial number vs just the model?

Manufacturers often change internal parts midway through a production year. The serial number identifies the specific "run" or date your unit was made, ensuring you order the exact replacement part that fits your specific build version.
