Frequently asked questions
Everything you need to know about LNNIW food warming mats, shipping and returns.
What is LNNIW?
LNNIW is a brand of electric food warming mats and warming trays designed to keep meals hot for family dinners, parties and buffets. lnniw.com is our official online store.
What is a food warming mat and how does it work?
A food warming mat is a flat, flexible electric heating surface. You place your serving dishes on it, choose a temperature and a timer, and the gentle heat keeps the food warm at the table. It has no open flame and rolls up for storage.
What temperature settings do LNNIW mats have?
Six adjustable levels: 122°F, 140°F, 158°F, 176°F, 194°F and 212°F (50–100°C), plus six preset timers from 1 to 6 hours with automatic shut-off.
What temperature keeps food at a safe serving temperature?
Food safety guidance from the USDA recommends holding cooked, hot food at 140°F (60°C) or above. Choose 140°F or higher for perishable dishes and check the food with a thermometer. Read our hot-holding guide.
Which dishes can I use on the mat?
Heat-safe glass, ceramic, stainless steel and enamelware dishes, as well as frying pans. Flat-bottomed dishes give the best contact and even heating.
Does the mat have a child lock?
Yes. After setting your temperature and timer, you can activate the child lock so settings can't be changed accidentally. On the grey and blue mats, long-press the power button.
Is a heat-resistant pad included?
The Dark Grey 36×15 in and Dark Blue 26×15 in warming mats include a detachable heat-resistant insulation pad to help protect the surface underneath.
How do I clean and store the mat?
Unplug and cool the mat, then wipe it with a soft damp cloth and a little mild dish soap. Dry it fully and roll it up gently for storage. Always check the user manual for model-specific instructions. See our cleaning guide.
Which size should I choose?
Choose 26×15 in for 2–3 dishes and everyday use, or 36×15 in for larger spreads of 4–6 dishes. Our size guide can help.
