My lg washer smells of smoke, but I get no alarm. My husband looked for fire hazards, but found none.

The bearing on the main spindle probably seized and the motor continued running and burned up the belt. The belt will need to be replaced, and whatever caused the issue in the first place will need to be remedied weather it was a bearing or something else.

You are probably using too much soap. You also need to make sure you're using HE detergent. To test this run the washer empty (no soap) and if you see bubbles inside that's left over soap that's still in the unit. If so, keep running it empty until the bubbles are gone then start using only about 1 tablespoon of soap per load. The washer uses about 1/10 of the water so you need to use 1/10 of the soap. Use the same amount of softner.

Momma, Maytag put out a service bullitin on this problem. TB26-72. This is a common problem on your model. Why don't you google the service bullitin and it will give you the instructions they have for this problem. If you can't find it, post back and I will post them for back.

The motor could be leaking oil. Pull the machine out and look for stains or puddles on the floor.

Whirlpool and Tide make a cleaner that you put into the washer and run it through a cycle. Front loaders get a build-up that cannot be cleaned by hand. Make sure you are using a detergent that is marked "HE". Do not overfill the detergent or softener cups. I've heard that other used a lot of bleach in a wash cycle to clear out the smell. Bleach is bad to use if you're on a septic system, though.
