In No Frost systems ice shouldn't build up. Ice layers mean automatic defrost isn't working or humid air is getting in.
Possible causes
- Failed defrost heater
- Faulty defrost sensor or timer
- Damaged door seal
- Frequent or prolonged door opening
Safe first checks you can do
Safety: unplug the appliance and close the water tap before any check, and never open the outer casing or electronic boards yourself.
- Check door closure and seal
- Don't put hot food inside

When do you need a technician?
Manual defrosting is temporary; if ice returns within days, the defrost system needs repair.

Should I chip ice off with a tool?
