Fix Steps:
1
Check if demo mode is activated - look for "DEMO" or "d" on display
2
To exit demo mode: Press and hold STOP/CLEAR for 3-5 seconds
3
Try heating a cup of water for 1 minute to test if heating works at all
4
Check if power level is set to LOW or 10% - reset to HIGH or 100%
5
Verify door closes completely with a solid click - test with paper between door
6
Clean door seal and frame with damp cloth - food particles prevent proper seal
7
Try unplugging microwave for 2 minutes then plug back in to reset
8
Check if child lock is preventing proper operation - usually STOP + START for 3 seconds
9
Test with different food - some foods heat slower than others
10
Ensure plate or container is microwave-safe - metal reflects waves and prevents heating
