Product review (5 stars): Dont call the repair man
Don't call a repair man, don't buy a new machine. Just about every thing I'd replaceable.  Make you find your machine model number, Google the part manual for your model and then Google the part number your need. It's that easy and most sites will give troubleshooting examples and even videos.

I ordered this part from amazon,  it was delivered the same day and ten minutes later... just like a new machine. Problem solved!
