4778W4A011E Genuine Supporter for LG Microwave Ovens, LG Microwave Internal Support Part Replacement

4778W4A011E is a genuine LG part that LG simply calls a supporter, a support piece used in LG microwave ovens. LG's own description doesn't say exactly where it sits, so the safest way to confirm fit is by number. Check 4778W4A011E against the part number on your old piece, or find it in the parts list for your microwave's model.

Replacing a broken microwave support part

Support parts hold other components in position, keeping a cover, tray mechanism or internal assembly steady and in line. When one cracks or goes missing, the part it carries can rattle, sit out of line or rub against moving parts. In a microwave that can mean noises while it runs, a turntable or cover that sits unevenly, or a panel that doesn't fit as it should. Because the description doesn't spell out the exact location, compare your old part's shape and mounting points carefully before ordering, and go by the number printed on it where you can.

Safety before you start

Unplug the microwave before doing anything. If the support sits inside the outer casing, leave the job to a qualified technician, because the high voltage capacitor can hold a dangerous charge even when the microwave is unplugged. Parts that sit inside the cooking cavity can usually be swapped without opening the case.
