Product review (5 stars): My washing machine works now!
My Neptune stopped spinning about a month ago.  When this happened, we noticed a faint burndy smell.  If you google the symptoms (Maytag Neptune doesn't spin, burnt smell), you may find that your problem was a "wax motor".  This was the case for my machine: the wax motor was bad and there were 2 parts on the circuit board that needed replacing.  According to the web, is a very common problem with these Maytags.

I called a repair man who wanted to replace the whole circuit board in addition to the wax motor, but my husband thought this kit was worth a try.  It did the job.  The instructions were excellent.

 My washer had been running great for 15 years and now it is back in operating condition.
