900402671 Genuine Microwave Lamp 25W T70 Right Angle Spade 6912W3B002D for LG, Smeg Microwaves MS2346S MH6589DRW MS-2342W MS2548GR

Microwave light gone out? Part 900402671 is a genuine 25W microwave lamp with right angle spade terminals, and it is the same lamp as LG part number 6912W3B002D. It is listed for a wide range of LG microwaves, among them the MS2346S, MS-2342W, MS2548GR and MH6589DRW, along with Smeg microwaves that take the 6912W3B002D globe. With more than 100 models on file, the number on your old lamp is the quickest way to confirm the match.

Microwave light not working? Time for a new lamp

The lamp lights up the cavity while the microwave runs and when the door is opened, so you can keep an eye on food without stopping the cycle. Like any filament globe, it eventually burns out, and the giveaway is a microwave that heats normally but stays dark inside. A lamp that flickers or only comes on when the door is tapped may have a loose spade connection rather than a broken filament. If a new globe still won't light, the fault is more likely in the door switch circuit or the control board, so test before buying more parts.

Replacing a microwave lamp safely

In most microwaves the lamp sits behind the outer cabinet, close to the high voltage capacitor, which can hold a dangerous charge even after the plug is pulled. For that reason the lamp is best replaced by a qualified technician. Always unplug the oven first, match the right angle spade terminals on the new globe to the old one and test the light before the cabinet goes back on.
