We have a whirlpool duet washing machine that is about 7 years old. During trhe spin cycle it makes a loud noise. Not the typical "airplane noise." There is also an odor. A burning engine odor. If you lower the speed on the spin cycle the noise and odor go away. Any ideas?

The rubber belt is worn and slipping under load. (like a fan belt)
There could also be something caught in the belt or pulleys; clear it out and it should work.
If worn, replace belt soon...


Hope this helps!

Sounds like the drum belt is worn. That would make a squealing noise and as it slips it could be heating up and causing the smell. Replace the belt. The following site tells how to do it:
