Check cube tray heater — should heat to melt ice from tray during harvest cycle. Test resistance: 10-40Ω
✓ Expected: 10-40Ω
Check freezer temperature — must be 0°F or below for ice making. If warmer, fridge has a cooling issue
✓ Expected: 0°F or below
For Samsung: check water filter cap O-ring — cracked O-ring on filter cap stops water flow to ice maker
